Summary of the Screening Assessment Report of Octamethylcyclotetrasiloxane

The Ministers of the Environment and of Health have conducted a screening assessment on Octamethylcyclotetrasiloxane (D4), CAS No. 556-67-2, a substance identified in the categorization of the Domestic Substances List as a high priority for action under the Ministerial Challenge. It was considered to pose an intermediate potential for exposure (IPE) to individuals in Canada and has been classified by another agency on the basis of reproductive toxicity. It was also found to meet all of the ecological categorization criteria, including persistence, bioaccumulation potential and inherent toxicity to aquatic organisms (PBiT), and it is known to be in commerce in Canada. This screening assessment examines various scientific information and develops conclusions based on a weight of evidence approach and using the precautionary approach as required under section 76.1 of the Canadian Environmental Protection Act, 1999.

Octamethylcyclotetrasiloxane, or D4, is an industrial chemical which was not manufactured by any company in Canada in 2006 in a quantity above the reporting threshold of 100 kg, but which is imported into the country in a total quantity between 1 000 000 and 10 000 000 kg as an essentially pure substance, in mixtures with other cyclic siloxanes, as a residual in silicone polymers, and in finished consumer products.

The principal sources of release of D4 to the environment are industrial processes and the use and disposal of personal care products. D4 may be released from industrial processes in which it is reacted to form silicone polymers and co-polymers and from blending, formulation and packaging operations. All of these operations take place in Canada.

D4 exhibits low experimental solubility in water, very high vapour pressure and high octanol-water partition coefficient values. It is expected to partition to air by volatilization and to sediments and soil by adsorption when released to surface water or terrestrial environments.

D4 is persistent in air, water and sediment, and has a high potential to accumulate in aquatic organisms. D4 is also judged to behave like a persistent organic pollutant (POP) and have the potential to travel to the Arctic. In addition, the experimental toxicity data show that the substance can cause long-term toxicity to aquatic organisms at low concentrations in water. D4 meets criteria for persistence and bioaccumulation potential as set out in the Persistence and Bioaccumulation Regulations.

Based principally on the weight of evidence-based assessments of the European Commission and the Danish Environmental Protection Agency (EPA), an important effect of D4 exposure is impaired fertility. However, the Danish EPA also identified the liver as a target organ for D4 exposures. The critical effect level for repeated-dose toxicity via inhalation is considered to be 420 mg/m³, based not only on increased liver weights, but also on effects observed in other organs (adrenals, thymus, lungs) in a three-month rat inhalation study. Comparison of the critical effect level for repeated dose effects via inhalation (420 mg/m³) and the conservative upper-bounding exposure estimate via inhalation for D4 results in an adequate margin of exposure. The critical effect level for repeated-dose toxicity via the oral route is considered to be 100 mg/kg bw/day, based on decreased serum estradiol in seven-day mouse studies and decreased body-weights and relative liver weights in fetuses in eight-day rat studies (D4 administered to pregnant females). Comparison of the critical effect level for repeated dose effects via the oral route (100 mg/kg bw/day) and the upper-bounding estimate of daily intake of D4 by the general population in Canada, results in an adequate margin of exposure.

Comparison of the critical effect level for repeated dose effects via the oral route (100 mg/kg bw/day) and a conservative upper-bounding estimate of daily intake of D4 via use of personal care products results in a margin of exposure of approximately 300. A more refined exposure assessment would result in considerably higher margins of exposure.

Based on the information available, it is proposed that this substance is entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity.

Based on the available information on its potential to cause harm to human health, it is proposed that D4 is not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

Proposed conclusion

Based on the information available, it is proposed that D4 meet one or more of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999. D4 is proposed to be persistent and bioaccumulative in accordance with the regulations, its presence in the environment results primarily from human activity, and it is not a naturally occurring radionuclide or a naturally occurring inorganic substance.

The draft Screening Assessment Report as well as the proposed risk management scope document for this substance are available on the Government of Canada’s Chemical Substances Web site (www.chemicalsubstances.gc.ca).

ANNEX

Summary of the Screening Assessment Report of Decamethylcyclopentasiloxane

Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), the Ministers of the Environment and of Health have conducted a screening assessment on Decamethylcyclopentasiloxane (D5) - Chemical Abstracts Service Registry Number 541-02-6. This substance was identified as a high priority for screening assessment and included in the Ministerial Challenge because it was found to meet the ecological categorization criteria for persistence, bioaccumulation potential and inherent toxicity (PBiT) to non-human organisms and it is known to be in commerce in Canada.

Although the categorization exercise did not determine D5 to be a priority for assessment with respect to risks to human health, a human health assessment of D5 was also conducted due to its structure and use pattern similarity to D4, also known as Octamethylcyclotetrasiloxane, a high priority for assessment for both human health and ecological risks under CEPA 1999.

D5 is an industrial chemical which was not manufactured by any company in Canada in 2006 in a quantity above the reporting threshold of 100 kg, but which is imported into the country as an essentially pure substance, in mixtures with other cyclic siloxanes, as a residual in silicone polymers, and in finished consumer products. From responses to a notice published under section 71 of CEPA 1999, it was determined that between 1 000 000 and 10 000 000 kg of D5 were imported into Canada in 2006.

D5 may be emitted to the environment from industrial processes in which it is reacted to form silicone polymers and co-polymers and from blending, formulation and packaging operations. All of these operations take place in Canada. The use of D5 as a commercial dry cleaning fluid and as an industrial degreaser may lead to atmospheric releases. The releases from industrial processes are expected to be to the atmosphere and wastewater. D5 will be released during the use of personal care products such as hair and skin care products, antiperspirants and others and these releases will be to air and wastewater.

D5 is persistent in air, water and sediment, and has a high potential to accumulate in aquatic organisms and some potential to biomagnify in terrestrial food-chains. D5 is also judged to behave like a persistent organic pollutant (POP) and has the potential for atmospheric transport over long distances from its emission sources. New experimental toxicity data suggest that the substance has a low potential for acute and chronic toxicity to pelagic organisms at concentrations up to its estimated solubility limit. Sediment toxicity data and mammalian studies also suggest that exposure to D5 may cause long-term adverse effects on sediment-dwelling organisms and organisms in the terrestrial compartment.

Based principally on the weight of the evidence-based assessment of the Danish Environmental Protection Agency (EPA), a potential effect for repeated-dose toxicity is carcinogenicity, as observed in a two-year rat study. It is noted that the uterine tumours in this study were observed at higher levels than the effects identified for the lung and liver in several other toxicity studies. The lung was identified as a target organ for inhalation exposures of D5 whereas the liver was identified as a target organ for oral and inhalation exposures. The critical effect level for repeated dose toxicity is considered to be 450 mg/m³ via the inhalation route (i.e. based on a significant increased incidence of pulmonary vascular mineralization as observed in a rat reproduction study). Comparison of the critical effect level for repeated dose effects via inhalation (450 mg/m³) and the conservative upper-bounding exposure estimate via inhalation for decamethylcyclotetrasiloxane, results in adequate margins of exposure. The critical effect level for repeated-dose toxicity is considered to be 100 mg/kg bw/day via the oral route based on increased liver weight in a 90-day rat study and using as support, the determinations of oral critical effect levels for the similar compounds, octamethylcyclotetrasiloxane and dodecamethylcyclohexasiloxane. Comparison of the critical effect level for repeated-dose effects via the oral route (100 mg/kg bw/day) and the upper-bounding estimates of daily intake of D5 by the general population in Canada results in adequate margins of exposure. Comparison of the critical effect level for repeated dose effects via the oral route (100 mg/kg bw/day) and a conservative upper-bounding estimate of daily intake of D5 via use of personal care products results in a margin of exposure of approximately 200. A more refined exposure assessment would result in considerably higher margins of exposure.

Based on the available information on its potential to cause ecological harm, it is proposed that D5 is entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity, or that constitute or may constitute a danger to the environment on which life depends. D5 meets criteria for persistence and bioaccumulation potential as set out in the Persistence and Bioaccumulation Regulations.

Based on the available information on its potential to cause harm to human health, it is proposed that D5 is not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

Proposed conclusion

Based on the information available, it is proposed that D5 meet one or more of the criteria set out in section 64 of CEPA 1999. D5 is proposed to be persistent and bioaccumulative in accordance with the regulations, its presence in the environment results primarily from human activity, and it is not a naturally occurring radionuclide or a naturally occurring inorganic substance.

Summary of the Screening Assessment Report of Dodecamethylcyclohexasiloxane

Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), the Ministers of the Environment and of Health have conducted a screening assessment on Dodecamethylcyclohexasiloxane (D6), Chemical Abstracts Service Registry Number 540-97-6. This substance was identified as a high priority for screening assessment and included in the Ministerial Challenge because it was found to meet the ecological categorization criteria for persistence, bioaccumulation potential and inherent toxicity (PBiT) to non-human organisms and it is known to be in commerce in Canada.

Although the categorization exercise did not determine D6 to be a priority for assessment with respect to risks to human health, a human health assessment of D6 was also conducted due to its structure and use pattern similarity to D4, also known as octamethylcyclotetrasiloxane, a high priority for assessment for both human health and ecological risks under CEPA 1999.

D6 is an industrial chemical which was not manufactured by any company in Canada in 2006 in a quantity above the reporting threshold of 100 kg, but which is imported into the country in a total quantity between 100 000 and 1 000 000 kg as an essentially pure substance, in mixtures with other cyclic siloxanes, as a residual in silicone polymers, and in finished consumer products.

D6 is persistent in air, water and sediment, and has a high potential to accumulate in aquatic organisms, and to biomagnify in terrestrial food-chains. D6 is also judged to behave like a persistent organic pollutant (POP) and have the potential to travel to the Arctic. New experimental toxicity data show that the substance has a low potential for acute and chronic toxicity to aquatic organisms at concentrations up to its solubility limit. However, results from model estimates suggest that D6 may have the potential to cause chronic harm to sensitive aquatic organisms.

With respect to human health, the liver was identified as a target organ for oral exposures and potentially inhalation exposures of D6. The critical effect level for repeated dose toxicity via the oral route is considered to be 100 mg/kg bw/day, based on increased liver weight, periportal lipidosis and thyroid follicular cell hypertrophy in a 4-week rat study. Comparison of the critical effect level for repeated dose effects via the oral route and the upper-bounding estimates of daily intake of D6 by the general population in Canada results in an adequate margin of exposure. Comparison of the critical effect level for repeated dose effects via the oral route and the conservative upper-bounding estimate of daily intake of D6 via personal care products results in a margin of exposure of approximately 500. A more refined exposure assessment would result in considerably higher margins of exposure.

Based on the information available, it is proposed that D6 is entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity. D6 meets criteria for persistence and bioaccumulation potential as set out in the Persistence and Bioaccumulation Regulations.

Based on the available information on its potential to cause harm to human health, it is proposed that D6 is not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

Proposed conclusion

Based on the information available, it is proposed that D6 meet one or more of the criteria set out in section 64 of the CEPA 1999. D6 is proposed to be persistent and bioaccumulative in accordance with the regulations, its presence in the environment results primarily from human activity, and it is not a naturally occurring radionuclide or a naturally occurring inorganic substance.

Summary of the Screening Assessment Report of Phenol, 2,4,6-tris(1,1-dimethylethyl)-

Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), the Ministers of the Environment and of Health have conducted a screening assessment on Phenol, 2,4,6-tris(1,1-dimethylethyl)- (2,4,6-tri-tert-butylphenol), Chemical Abstracts Service Registry Number 732-26-3. This substance was identified as a high priority for screening assessment and included in the Ministerial Challenge because it was found to meet the ecological categorization criteria for persistence, bioaccumulation potential and inherent toxicity to non-human organisms and is known to be in commerce in Canada.

The substance 2,4,6-tri-tert-butylphenol was not considered to be a high priority for assessment of potential risks to human health, based upon application of the simple exposure and hazard tools developed by Health Canada for categorization of substances on the Domestic Substances List. Therefore, this assessment focuses on information relevant to the evaluation of ecological risks.

The substance 2,4,6-tri-tert-butylphenol is an antioxidant. It is used in Canada and elsewhere as a fuel, oil, gasoline and lubricant additive. The substance is not naturally produced in the environment. Although it was not reported to be manufactured in Canada above the reporting threshold, total imports were reported to be in a quantity between 10 000 and 100 000 kg in the year 2000. Voluntary submissions received in 2007 reported a quantity between 1 000 and 10 000 kg of this substance being imported into Canada in the calendar year 2006. This substance was also reported to be used below the reporting threshold. Quantities of 2,4,6-tri-tert-butylphenol imported into Canada, along with its use as a fuel, oil and lubricant additive, indicate that this chemical may potentially be released broadly into the Canadian environment.

Based on certain assumptions and reported use patterns, most of 2,4,6-tri-tert-butylphenol may be destroyed through the combustion of fuel/oil. Small proportions are estimated to be released to water (0.8%), air (1.6%) and soil (0.1%). There is also a proportion estimated to be transferred to waste disposal sites (5.1%). Given this substance’s physical and chemical characteristics, it is expected to strongly adsorb to soil and sediment. This substance is not likely to be metabolized (given its highly branched chemical structure) and will have a tendency to partition to lipids (fat) of organisms because of its hydrophobic nature.

Based on its physical and chemical properties, 2,4,6-tri-tert-butylphenol does not degrade quickly in the environment; it is expected to be persistent in water, soil and sediments. Empirical and modelled data indicate that this substance also has the potential to accumulate in organisms and may biomagnify in trophic food chains. The substance has been determined to meet the persistence and bioaccumulation criteria as set out in the Persistence and Bioaccumulation Regulations. In addition, acute aquatic toxicity values suggest that the substance is highly hazardous to aquatic organisms.

Given that long-term risks associated with persistent and bioaccumulative substances cannot at present be reliably predicted, quantitative risk estimates have limited relevance. Furthermore, since accumulations of such substances may be widespread and difficult to reverse, a conservative response to uncertainty is justified.

Based on the information available, it is proposed that 2,4,6-tri-tert-butylphenol is entering or may enter the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity.

Proposed conclusion

Based on the information available, it is proposed that 2,4,6-tri-tert-butylphenol meet one or more of the criteria set out in section 64 of the CEPA 1999. 2,4,6-tri-tert-butylphenol is proposed to be persistent and bioaccumulative in accordance with the regulations, its presence in the environment results primarily from human activity, and it is not a naturally occurring radionuclide or a naturally occurring inorganic substance.

Summary of the Screening Assessment Report of Benzenesulfonic acid, 3,3′-[(9,10-dihydro-9,10-dioxo1,4-anthracenediyl)diimino]bis[2,4,6-trimethyl-, disodium salt

Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), the Ministers of the Environment and of Health have conducted a screening assessment on Benzenesulfonic acid, 3,3′-[(9,10-dihydro-9,10-dioxo-1,4-anthracenediyl) diimino]bis[2,4,6-trimethyl-, disodium salt (Acid Blue 80), Chemical Abstracts Service Registry Number 4474-24-2. This substance was identified as a high priority for screening assessment and included in the Ministerial Challenge because it was found to meet the ecological categorization criteria for persistence, bioaccumulation potential and inherent toxicity to non-human organisms and is believed to be in commerce in Canada.

The substance Acid Blue 80 was not considered to be a high priority for assessment of potential risks to human health, based upon application of the simple exposure and hazard tools developed by Health Canada for categorization of substances on the Domestic Substances List. Therefore, this assessment focuses on information relevant to the evaluation of ecological risks.

Acid Blue 80 is a discrete organic substance that is used in Canada and elsewhere as a dark-blue colourant dye in processing and synthesizing cleaning products in several industrial and commercial sectors. Acid Blue 80 is also used in printing inks, in paints, and in plastic colourants. The substance is not naturally produced in the environment. Between 1 000 001 and 10 000 000 kg of Acid Blue 80, contained mainly in cleaning products, were imported into Canada in 2006. Such reported quantity and uses indicate that Acid Blue 80 could be released into the Canadian environment.

Based on certain assumptions and reported use patterns, most of the substance is expected to end up in surface water, with a relatively small fraction being transferred to waste disposal sites. It is not expected to be present in significant quantities in other media.

Based on its physical and chemical properties, Acid Blue 80 does not have the potential to accumulate in aquatic organisms, and an empirical acute aquatic toxicity value suggests that the substance is not highly hazardous to aquatic organisms. However, Acid Blue 80 does not degrade quickly in the environment. It is expected to be persistent in water, soil and sediments based on criteria defined in the Persistence and Bioaccumulation Regulations. Moreover, the large importation volumes of Acid Blue 80 into Canada, along with information on its uses, indicate potential for releases into the Canadian environment. Once released into the environment, it is found mainly in water. Risk quotient calculations, comparing estimates of exposure with a predicted no effect concentration, indicate potential for risk to aquatic organisms over wide areas in Canada.

Based on the information available, it is proposed that Acid Blue 80 is entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity.

Proposed conclusion

Based on the information available, it is proposed that Acid Blue 80 meet one or more of the criteria set out in section 64 of CEPA 1999.

ANNEX

Summary of the Screening Assessment Report of Thiourea

The Ministers of the Environment and of Health have conducted a screening assessment of thiourea, Chemical Abstracts Service Registry Number 62-56-6, a substance identified in the categorization of the Domestic Substances List as a high priority for action under the Ministerial Challenge. Thiourea was identified as a high priority as it was considered to pose greatest potential for exposure (GPE) to individuals in Canada and had been classified by other agencies on the basis of carcinogenicity and reproductive/developmental toxicity. Thiourea does meet the ecological categorization criteria for persistence in water, soil and sediment but it does not meet the criteria for bioaccumulation potential or inherent toxicity to aquatic organisms. Therefore, the focus of this assessment of thiourea relates to human health.

According to information reported under section 71 of the Canadian Environmental Protection Act, 1999, thiourea was imported into Canada in 2006 in a quantity ranging between 10 000 kg and 100 000 kg. Thiourea is used in metal finishing solutions and in etching treatments used for printed circuit boards, and as a reducing agent in the production of thiourea dioxide, a chemical intermediate, a reactant in the copper refinery industry and a rust inhibitor. In addition, thiourea may be included in silver polish, tarnish removers, metal cleaners, black and white photographic chemicals, blueprint papers and pharmaceutical synthesis.

Exposure to thiourea via the general environment is considered to be negligible; therefore, the predominant source of general population exposure to thiourea is expected to be as a result of its presence in consumer products.

Based principally on the weight of evidence based assessments of international or national agencies, a critical effect for the characterization of risk to human health for thiourea is carcinogenicity. The substance induced tumours at multiple sites in male and female rats and in the mammary gland of mice. Although thiourea appears to be only weakly genotoxic, the mode of induction of tumours has not been fully elucidated; therefore, it cannot be precluded that the tumours observed in experimental animals resulted from direct interaction with genetic material. In addition, the margins between upper-bounding estimates of exposure through inhalation and through dermal routes during use of consumer products containing thiourea and critical effect levels for non-cancer effects in short-term and reproductive toxicity studies may not be adequate to account for the uncertainties in the databases on exposure and effects, particularly in view of the uncertainties in the mode of induction of tumours.

On the basis of the carcinogenicity of thiourea, for which there may be a probability of harm at any level of exposure, as well as the potential inadequacy of the margins of exposure for non-cancer effects, and applying a precautionary approach, it is proposed that thiourea be considered as a substance that may be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

On the basis of ecological hazard and reported releases of thiourea, it is proposed that this substance is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity, or that constitute or may constitute a danger to the environment on which life depends. Although thiourea does meet criteria for persistence, it does not meet the criterion for bioaccumulation potential as set out in the Persistence and Bioaccumulation Regulations.

Proposed conclusion

Based on the information available, it is proposed that thiourea meet one or more of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999.

Summary of the Screening Assessment Report of 1,3-Butadiene,
2-methyl-

The Ministers of the Environment and of Health have conducted a screening assessment of 1,3-Butadiene, 2-methyl- (isoprene), Chemical Abstracts Service Registry Number 78-79-5, a substance identified in the categorization of the Domestic Substances List as a high priority for action under the Ministerial Challenge as it was considered to pose greatest potential for exposure to individuals in Canada (GPE) and had been classified by other agencies on the basis of carcinogenicity and mutagenicity. Since the substance did not meet the criteria for persistence, bioaccumulation or inherent toxicity to aquatic organisms, the focus of this assessment on 1,3-Butadiene, 2-methyl- relates to human health aspects.

Under information reported pursuant to section 71 of Canadian Environmental Protection Act, 1999, the total quantity of isoprene manufactured in Canada in 2006 exceeded 10 000 000 kg and the total quantity imported ranged from 1 000 000 to 10 000 000 kg. This substance is used mainly as a monomer in the production of polyisoprene, butyl rubber and styrene-isoprene-styrene (SIS) rubber. Polyisoprene is subsequently used in the production of vehicle tires and a wide variety of products, including paint resins, footwear, adhesives and molded goods. Butyl rubber is typically used in the manufacture of inner tubes, while SIS rubber is used in pressure sensitive adhesives. Isoprene is also used in the formulation of viscosity improvers for motor oil and in the production of agrochemicals, pharmaceuticals and other substances.

Isoprene is emitted into the environment from both natural and anthropogenic sources, and the principal route of exposure for the general population will likely be through inhalation of ambient and indoor air. Off-gassing of isoprene from consumer products manufactured from polyisoprene may also contribute to the levels of the substance in indoor air.

Based principally on the weight of evidence-based assessments of several international and national agencies, a critical effect for the characterization of risk to human health is carcinogenicity, based on observation of tumours at multiple organ sites in rats and mice. Isoprene was also genotoxic in several in vivo assays. Therefore, although the mode of action has not been fully elucidated, it cannot be precluded that tumours observed in experimental animals resulted from direct interaction with genetic material.

On the basis of carcinogenicity, for which there may be a probability of harm at any level of exposure, as well as the potential inadequacy of the margin between concentrations of isoprene in indoor air and levels associated with non-cancer effects in the thymus in a subchronic study, and applying a precautionary approach, it is proposed that isoprene be considered as a substance which may be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

On the basis of low ecological hazard and reported releases of isoprene, it is proposed that this substance is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity, or that constitute or may constitute a danger to the environment on which life depends. As set out in the Persistence and Bioaccumulation Regulations, isoprene does not meet the criteria for persistence in air, water, soil or sediment, nor does it meet the criterion for bioaccumulation potential.

Proposed conclusion

Based on the information available, it is proposed that isoprene meet one or more of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999.

Whereas it is proposed that epichlorohydrin meet one or more of the criteria set out in section 64 of the Act,

Summary of the Screening Assessment Report of Oxirane, (chloromethyl)-

The Ministers of the Environment and of Health have conducted a screening assessment of Oxirane, (chloromethyl)- (epichlorohydrin), Chemical Abstracts Service Registry Number 106-89-8, a substance identified in the categorization of the Domestic Substances List as a high priority for action under the Ministerial Challenge. Epichlorohydrin was identified as a high priority as it was considered to pose greatest potential for exposure to individuals in Canada (GPE) and had been classified by other agencies on the basis of carcinogenicity. Since the substance did not meet the criteria for persistence, bioaccumulation or inherent toxicity to aquatic organisms, the focus of this assessment on epichlorohydrin relates to human health aspects.

Under information reported pursuant to section 71 of CEPA 1999, in 2006 epichlorohydrin was not manufactured in or imported into Canada by any company above the 100 kg threshold. It is likely that epichlorohydrin is being imported in very small amounts as residual monomer in products containing epoxy resin or other resins made using epichlorohydrin. Direct use of epichlorohydrin by consumers is not expected. The principal use of epichlorohydrin is in the production of epoxy and phenoxy resins, which are primarily used in protective coatings and thermoplastic polymers. It may also be used for the production of synthetic glycerol, and in the chemical synthesis of pharmaceutical products, polyols, and surface active agents for washing products and toiletries. Polymers made with epichlorohydrin are used as additives in papermaking, as cross-linking agents for starches, and as anion-exchange resins and flocculants used in treating drinking and wastewater.

In Canada since epichlorohydrin is present only as a residual, environmental and consumer product exposures are expected to be low to negligible. No empirical data were identified regarding measured concentrations of epichlorohydrin in environmental media (i.e. air, water, soil and food) in Canada. Based on its possible uses, oral exposure to epichlorohydrin via food and/or drinking water may occur at low levels for the general population of Canada. Contributions from ambient air and soil are expected to be negligible due to the lack of manufacture in and/or import of this substance into Canada. There is also the possibility of low level exposure to epichlorohydrin via inhalation during the use of consumer products that contain residual amounts of epichlorohydrin monomer.

Based principally on the weight of evidence-based assessments of several international and national agencies, a critical effect for the characterization of risk to human health is carcinogenicity, based on observation of tumours in rats and tumour initiation in mice. Epichlorohydrin was genotoxic in a wide range of in vitro and in vivo experimental systems, as well as in investigations of occupationally exposed humans. Therefore, although the mode of action has not been fully elucidated, it cannot be precluded that tumours observed in experimental animals resulted from direct interaction with genetic material.

On the basis of carcinogenicity, for which there may be a probability of harm at any level of exposure, it is proposed that epichlorohydrin be considered as a substance which may be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

On the basis of moderate ecological hazard and low reported releases of epichlorohydrin, it is proposed that this substance is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity, or that constitute or may constitute a danger to the environment on which life depends. Although epichlorohydrin does meet the criterion for persistence, it does not meet the criterion for bioaccumulation potential as set out in the Persistence and Bioaccumulation Regulations.

Proposed conclusion

Based on the information available, it is proposed that epichlorohydrin meet one or more of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999.

Summary of the Screening Assessment Report of
Acetic Acid Ethenyl Ester

The Ministers of the Environment and of Health have conducted a screening assessment on Acetic acid ethenyl ester, otherwise commonly referred to as vinyl acetate monomer, Chemical Abstracts Service Registry Number 108-05-4. This substance was identified in the categorization of the Domestic Substances List as a high priority for action under the Ministerial Challenge.

For the purposes of this assessment, Acetic acid ethenyl ester will be subsequently referred to as vinyl acetate. Vinyl acetate was identified as a high priority as it was considered to pose greatest potential for exposure to individuals in Canada (GPE) and has been classified by another agency on the basis of carcinogenicity. As this substance was determined not to meet the ecological categorization criteria for persistence, bioaccumulation potential, or inherent toxicity to aquatic organisms, the focus of this screening assessment relates to human health aspects.

Vinyl acetate is an industrial chemical, a monomer precursor, used as a raw material or intermediate to synthesize polymers and (co)polymers for use in formulations of various end-use products. It is the most important vinyl ester.

Vinyl acetate was not manufactured in Canada in a quantity above the reporting threshold of 100 kg in 2006, but was imported into the country in a quantity greater than 10 000 000 kg. In Canada 99.9% of all imported vinyl acetate was for use as a monomer precursor for the production of poly(vinyl acetate) and vinyl acetate (co)polymers, especially, ethylene vinyl acetate (co)polymers. These formulated polymers are subsequently manufactured into adhesives for packaging and construction, water-based paints and coatings.

Exposures to vinyl acetate in Canada can occur via the oral, dermal and inhalation routes of exposure. Indirect exposures occur from anthropogenic releases during manufacturing, processing, storage, spills, transport and waste disposal. Direct exposures occur upon exposure to residuals of unpolymerized vinyl acetate migrating from or contained in consumer end-use products (cosmetics, paints, resin adhesives, tobacco smoke) and food contact plastic materials such as poly(vinyl acetate) and ethylene vinyl acetate (co)polymers, with trace residues of vinyl acetate.

Industrial releases in Canada are primarily to ambient air and will remain in the vapour state and undergo free radical photolytic hydroxylation yielding a half-life between 10 to 15 hours. Vinyl acetate atmospheric degradation will also occur by ozonation yielding a half-life under four days. Based on physical and chemical properties as well as fugacity modeling, vinyl acetate has been found to remain in the environmental media to which it is released.

Based principally on the weight of evidence assessment of the International Agency for Research on Cancer (IARC), a critical effect for characterization of risk to human health for vinyl acetate is carcinogenicity. Tumours of the nasal cavity in male and female rats were observed following inhalation exposure to vinyl acetate. More recent studies also reported squamous cell carcinomas of the upper digestive tract in both sexes of mice and rats following oral exposure to vinyl acetate. Vinyl acetate was also found to be genotoxic in human cells in vitro and in animals in vivo. As the mode of tumour induction is not considered to be fully elucidated, it cannot be precluded that the tumours observed in experimental animals resulted from direct interaction of vinyl acetate with genetic material.

The margin of exposure based on non-neoplastic effects (lesions of respiratory and upper digestive tracts and reduced body weight gain) and the upper bounding estimates of exposure to the general population derived from environmental media are adequate. However, the margin of exposure for non-neoplastic effects (respiratory distress and hunched posture) and consumer product exposure scenarios may not be adequate to account for uncertainties in the databases on exposure and effects.

On the basis of the carcinogenicity of vinyl acetate, for which there may be a probability of harm at any level of exposure, as well as the potential inadequacy of the margins of exposure for non-cancer effects, and applying a precautionary approach, it is proposed that vinyl acetate be considered as a substance that may be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

On the basis of ecological hazard and reported releases of vinyl acetate, it is proposed that this substance is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity, or that constitute or may constitute a danger to the environment on which life depends. Vinyl acetate does not meet the criteria for persistence and bioaccumulation potential as set out in the Persistence and Bioaccumulation Regulations.

Proposed conclusion

Based on the information available, it is proposed that vinyl acetate meet one or more of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999.

ANNEX

Summary of the Screening Assessment Report of
C.I. Pigment Yellow 34

The Ministers of the Environment and of Health have conducted a screening assessment of C.I. Pigment Yellow 34, Chemical Abstracts Service Registry Number 1344-37-2, a substance identified in the categorization of the Domestic Substances List as a high priority for action under the Ministerial Challenge. The substance C.I. Pigment Yellow 34 was identified as a high priority as it was considered to pose greatest potential for exposure (GPE) to individuals in Canada and had been classified by other agencies on the basis of carcinogenicity, reproductive toxicity and developmental toxicity. The substance met the ecological categorization criteria for persistence and inherent toxicity to aquatic organisms. Therefore, the focus of this assessment of C.I. Pigment Yellow 34 relates to human health and ecological aspects.

Under information reported pursuant to section 71 of the Canadian Environmental Protection Act, 1999, in 2006 C.I. Pigment Yellow 34 was reported to be manufactured in and imported into Canada. After exports, the amount remaining for use in this country ranged between 1 000 000 and 10 000 000 kg. It is primarily used for plastic formulation for commercial applications and export; commercial, non-consumer paints and coatings; and commercial printing inks or coatings used for plastics and certain outdoor applications such as commercial identification decals.

There were no empirical data identified regarding measured concentrations of C.I. Pigment Yellow 34 in environmental media (i.e. air, water, soil and food) in Canada. Given the physical and chemical properties of this substance, exposure to C.I. Pigment Yellow 34 is expected to be negligible via drinking water, ambient air or consumer products. Exposure to the general population in Canada is expected to be predominantly from soils, although these exposures are expected to be low due to the primarily commercial use of the substance, very limited industrial releases, and the encapsulation and incorporation of the substance into a solid matrix. However, these exposures could not be quantified due to lack of measured concentrations.

Based principally on the weight of evidence based classification of C.I. Pigment Yellow 34 by the European Commission, and the assessment of hexavalent chromium and inorganic lead compounds by several national and international agencies, a critical effect for the characterization of risk to human health is carcinogenicity. The substance C.I. Pigment Yellow 34, together with lead chromate and C.I. Pigment Red 104, was carcinogenic in rats after subcutaneous and intramuscular administration and these animal studies are supported by epidemiological studies, which indicate an increased frequency of lung cancer in chromate pigment production workers. As well, C.I. Pigment Yellow 34 or its principal components were genotoxic in a limited number of in vitro and in vivo experimental systems.

On the basis of the carcinogenicity of C.I. Pigment Yellow 34, for which there may be a probability of harm at any level of exposure, and applying a precautionary approach, it is proposed that C.I. Pigment Yellow 34 be considered as a substance that may be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

On the basis of ecological hazard and reported releases of C.I. Pigment Yellow 34, it is proposed that this substance is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity, or that constitute or may constitute a danger to the environment on which life depends. The substance C.I. Pigment Yellow 34 meets the criteria for persistence as set out in the Persistence and Bioaccumulation Regulations.

Proposed conclusion

Based on the information available, it is proposed that C.I. Pigment Yellow 34 meet one or more of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999.
