ANNEX

Summary of the draft screening assessment of melamine

Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of 1,3,5-triazine-2,4,6-triamine (CAS RN 108-78-1), commonly known as melamine, a substance included in the Certain Organic Flame Retardants (OFR) Substance Grouping under Canada’s Chemicals Management Plan, which includes 10 organic substances that have a similar function: application to materials to slow the ignition and spread of fire. Melamine was identified as a priority for assessment as it met the categorization criteria under subsection 73(1) of CEPA. A draft screening assessment for melamine was published in October 2016. Significant new information subsequently became available regarding exposure to products available to consumers, specifically foam products containing flame retardants such as melamine. As a result, the draft assessment was updated and is presented here.

Melamine does not occur naturally in the environment. It is not manufactured in Canada; however, imports of melamine, as a pure substance or blended into products, in the range of 10 to 100 million kilograms were reported for the year 2011. In Canada, melamine has numerous industrial applications; its predominant use is in the manufacture of polyurethane foams and melamine-based resins for application in laminates, plastics, paints and coatings. Globally, melamine is used primarily in the synthesis of melamine–formaldehyde resins for similar applications, and in adhesives and moulding compounds. Due to its high nitrogen content, melamine has also been used globally as a fertilizer. In Canada, sources of environmental exposure to melamine are primarily from waste streams or effluents of manufacturing of melamine-based resins, and, to a lesser degree, from processing plants using melamine to manufacture products with flame retardant properties. Discharges to the environment can be direct or via municipal wastewater treatment systems.

Melamine is a compact and stable molecule characterized by high water solubility, negligible vapour pressure, and low to negligible organic carbon–water and octanol–water partition coefficients. Monitoring of melamine in environmental media has not been conducted in Canada. When released to the environment, melamine is expected to predominantly reside in water and, to a lesser degree, in soil, depending on the compartment of release.

Melamine does not degrade rapidly in the environment; it has a long half-life in air, and has relatively slow biodegradation rates in water and soil. Melamine has a limited potential to bioaccumulate in tissues of organisms. It has very low bioconcentration factors in fish, and residue clearance rates from numerous organisms including mammals, fish and birds are known to be fast.

Based on empirical evidence from short- and long-term studies, melamine has a low toxicity to aquatic and soil-dwelling organisms. As the toxic effects of melamine exposure were more pronounced in long-term studies and those encompassing sensitive life stages, results from these types of studies were generally more informative. In contrast, in the multiple short-term studies, the toxicity limit for melamine could not be defined since the highest concentration tested showed no effects.

It is expected that melamine may be released to the Canadian environment as a result of industrial processing activities. Although melamine can be found in products available for consumer or commercial use, it is expected that release to the environment via this route is minimal. Industrial scenarios, where melamine is released to water, were developed to provide estimates of exposure. Risk quotient analyses, integrating conservative estimates of exposure with toxicity information, were performed for the aquatic compartment. These analyses showed that melamine risk to the environment in Canada is unlikely.

Considering all available lines of evidence presented in this updated draft screening assessment, there is a low risk to the environment from melamine. It is proposed to conclude that melamine does not meet the criteria under paragraph 64(a) or (b) of CEPA as it 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 main sources of exposure to melamine for the general population in Canada are expected to be from the use of products available to consumers, food and environmental media (water, soil). Biomonitoring data were also available from relevant populations (United States).

Based principally on the weight-of-evidence assessments of international agencies and available information, critical effects associated with exposure to melamine are carcinogenicity and effects on the urinary system. Available information indicates that melamine is not genotoxic. For infants, toddlers and young individuals (up to 18 years old), comparisons between levels associated with critical effects in animal studies and estimates of exposure from lying on foam-containing mattresses or furniture containing melamine are considered to be potentially inadequate to address uncertainties in the health effects and exposure databases. For all other types of exposures (from environmental media and food or from use of products available to consumers of all age groups), comparisons between levels associated with critical effects in animal studies and estimates of exposure were considered adequate to address uncertainties in the health effects and exposure databases.

On the basis of the potential inadequacy of the margins between estimates of exposure and critical effect levels in experimental animals in this updated draft screening assessment, it is proposed to conclude that melamine meets the criteria under paragraph 64(c) of CEPA as it is entering or may enter 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 overall conclusion

It is therefore proposed to conclude that melamine meets one or more of the criteria set out in section 64 of CEPA. It is also proposed to conclude that melamine meets the persistence criteria, but not the bioaccumulation criteria, as set out in the Persistence and Bioaccumulation Regulations of CEPA.

The draft screening assessment and the risk management scope document for this substance are available on the Canada.ca (Chemical Substances) website.

Summary of the draft screening assessment of p-toluenesulfonic acid

Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of benzenesulfonic acid, 4-methyl-, hereinafter referred to as p-toluenesulfonic acid (PTSA). The Chemical Abstracts Service Registry Number (CAS RN) for PTSA is 104-15-4. This substance was identified as a priority for assessment as it met categorization criteria under subsection 73(1) of CEPA.

PTSA does not naturally occur in the environment. According to information submitted in response to a CEPA section 71 survey, 141 600 kg of PTSA were imported into Canada in 2011 and no manufacturing was reported.

The ecological risk of PTSA was characterized using the ecological risk classification of organic substances (ERC), which is a risk-based approach that employs multiple metrics for both hazard and exposure, with weighted consideration of multiple lines of evidence for determining risk classification. Hazard profiles are based principally on metrics regarding mode of toxic action, chemical reactivity, food web–derived internal toxicity thresholds, bioavailability, and chemical and biological activity. Metrics considered in the exposure profiles include potential emission rate, overall persistence, and long-range transport potential. A risk matrix is used to assign a low, moderate or high level of potential concern for substances on the basis of their hazard and exposure profiles. Based on the outcome of the ERC analysis, the substance is considered unlikely to cause ecological harm.

Considering all available lines of evidence presented in this draft screening assessment, there is a low risk of harm to the environment from PTSA. It is proposed to conclude that PTSA does not meet the criteria under paragraph 64(a) or (b) of CEPA as it 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.

In Canada, PTSA is primarily used in the manufacture of paints and coatings, and of plastic and rubber materials. Exposure of the general population to PTSA is primarily from use of cosmetics (face lotion, permanent hair dye, and hair conditioner), an adhesive for crack repair, and conversion varnish sprays (catalyst-activated coating for interior wood furnishings).

Although PTSA has not been reviewed internationally, hydrotropes, including salts of PTSA, have been reviewed through the Cooperative Chemicals Assessment Programme of the Organisation for Economic Co-operation and Development (OECD). These OECD assessments were used to inform the health effects characterization of PTSA in this screening assessment. On the basis of available health effects information for PTSA and analogues in laboratory studies, the substance was not found to have genotoxic, carcinogenic, reproductive or developmental effects, and no systemic adverse effects were observed in repeated-dose studies with PTSA or its analogues up to the limit dose of 1 000 mg/kg bw/day. Given the low hazard potential of PTSA, estimates of exposure to the general population were not derived as the risk to human health is considered to be low.

On the basis of the information presented in this draft screening assessment, it is proposed to conclude that PTSA does not meet criteria under paragraph 64(c) of CEPA as it is not entering the environment in a quantity or concentration under conditions that constitute or may constitute a danger in Canada to human life or health.

Proposed overall conclusion

It is proposed to conclude that p-toluenesulfonic acid does not meet any of the criteria set out in section 64 of CEPA.

The draft screening assessment for this substance is available on the Canada.ca (Chemical Substances) website.

ANNEX

Summary of the screening assessment of the Triarylmethanes Group

Pursuant to section 68 or 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of six substances referred to collectively under the Chemicals Management Plan as the Triarylmethanes Group. These six substances were identified as priorities for assessment as they met categorization criteria under subsection 73(1) of CEPA or were considered a priority on the basis of other concerns. A seventh substance was initially included in the group; however, it was determined to be of low concern through other approaches, and the conclusion for this substance is provided in a separate report.footnote 2 Accordingly, this screening assessment addresses the six substances listed in the table below. The six substances addressed in this screening assessment will hereinafter be referred to as the Triarylmethanes Group.

Triarylmethanes are primarily used as colouring agents and do not occur naturally in the environment. They are used as dyes and/or pigments in inks, toners, and colourants, in paper products and manufactured items, and potentially in food packaging materials, for commercial and consumer use. Substances in this group are also used in other products available to consumers, including cosmetics (e.g. body cream, hair products, hair dyes, makeup, perfume), cleaning products, and water treatment products for aquarium fish, as well as in additional industrial and laboratory products. Brilliant Blue FCF is also used in food, natural health products, pest control products, prescription and non-prescription drugs, and a range of additional products available to consumers. According to information submitted for the reporting years of either 2008 or 2011, all six substances were imported into Canada, each in quantities ranging from 1 000 to 100 000 kg, and Brilliant Blue FCF was manufactured in Canada in a quantity ranging from 100 to 1 000 kg.

Substances in the Triarylmethanes Group may be released to the Canadian environment from their use in Canada in paper dyeing and de-inking, as well as from the formulation, manufacture and consumer use of products containing these substances. Releases are expected to the aquatic environment from both diffuse and point sources. Releases of some of these substances to terrestrial environments are also possible. If released to the aquatic environment, Pigment Blue 61 is likely to behave like a particle and settle to bed sediment. The other triarylmethane substances will be charged at environmentally relevant pH and will tend to sorb to dissolved and suspended solids. Therefore, these substances may potentially be transported in the water column or settle to bed sediment. Substances in the Triarylmethanes Group tend to persist in water, sediment and soil. They have a low potential to bioaccumulate in the lipids of aquatic organisms; however, the non-sulfonated dyes (i.e. Basic Violet 3, Malachite Green, Basic Violet 4 and Basic Blue 7) instead may bind to proteins and accumulate in other types of fish tissue.

Experimental acute toxicity data for the non-sulfonated dyes show they have the potential to cause adverse effects to aquatic organisms at low concentrations. Adverse effects in aquatic organisms were observed for Brilliant Blue FCF at relatively higher concentrations, whereas no effects were observed at the solubility limit for Pigment Blue 61. Ecological exposure scenarios were developed for down-the-drain releases from uses of products containing these substances and for releases from industrial sites. Risk quotient analyses were conducted to compare estimated aquatic concentrations to adverse effect concentrations in aquatic organisms for different exposure scenarios. Scenarios for paper dyeing and paper de-inking indicated that the non-sulfonated triarylmethane dyes pose a risk to aquatic organisms, whereas the scenarios for general formulation/product handling and consumer uses did not. Exposure scenarios for Brilliant Blue FCF did not show a risk to aquatic organisms and Pigment Blue 61 is not expected to pose a risk to aquatic organisms as it is expected to behave more like a particle and is not likely to be bioavailable.

Considering all available lines of evidence presented in this screening assessment, there is a risk of harm to the environment from Basic Violet 3, Malachite Green, Basic Violet 4, and Basic Blue 7. It is concluded that Basic Violet 3, Malachite Green, Basic Violet 4, and Basic Blue 7 meet the criteria under paragraph 64(a) of CEPA as they are 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. However, it is concluded that Basic Violet 3, Malachite Green, Basic Violet 4, and Basic Blue 7 do not meet the criteria under paragraph 64(b) of CEPA as they are not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger to the environment on which life depends. It is also concluded that Pigment Blue 61 and Brilliant Blue FCF do not meet the criteria under paragraph 64(a) or (b) of CEPA as they are 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.

For the general population of Canada, the predominant sources of exposure to dye substances in the Triarylmethanes Group are the use of products available to consumers that contain these substances and from environmental media (e.g. drinking water). Potential oral exposures to Basic Violet 3, Malachite Green, Basic Violet 4, Basic Blue 7 and Brilliant Blue FCF were estimated based on potential levels in drinking water. Potential dermal and oral exposures to Brilliant Blue FCF were derived from the use of natural health products and cosmetics, as well as oral exposures from its use as a food additive. Potential exposures to Malachite Green, Basic Violet 4 and Basic Blue 7 were derived from the use of cosmetics (hair dyes). Potential inhalation exposure to Brilliant Blue FCF from the use of perfume was also characterized. Inhalation exposure to the remaining substances in the Triarylmethanes Group was not considered to be of concern due to their negligible volatility, as well as their potential uses. Given its physical and chemical properties and identified uses, exposure to Pigment Blue 61 for the general population of Canada is not expected.

In laboratory studies, Basic Violet 3 is not observed to cause developmental or reproductive toxicity, but is genotoxic and carcinogenic. On the basis of health effects information for a structurally related substance, the critical health effect for Malachite Green is developmental toxicity. Pigment Blue 61 was not identified as posing a high hazard to human health on the basis of classifications by other national or international agencies for carcinogenicity, genotoxicity, developmental toxicity or reproductive toxicity. Basic Violet 4 and the structurally related substance Basic Blue 7 are not genotoxic. On the basis of health effects information on structurally related substances, Basic Violet 4 and Basic Blue 7 are not considered to be developmental or reproductive toxicants, but may be carcinogenic. Brilliant Blue FCF is poorly absorbed orally and dermally, is not a developmental or reproductive toxicant, is not genotoxic, and is not carcinogenic.

For Basic Violet 3, Basic Violet 4, Basic Blue 7, and Brilliant Blue FCF, comparisons of levels of exposure to the general population and levels at which critical health effects were observed result in margins of exposure considered adequate to address uncertainties in the health effects and exposure databases for both non-cancer and cancer effects. In contrast, similar comparisons of exposure from the use of Malachite Green in hair dye resulted in margins of exposure that are considered potentially inadequate to address uncertainties in the health effects and exposure databases, particularly since the critical health effects were observed at the lowest tested dose.

On the basis of the information presented in this screening assessment, it is concluded that Malachite Green meets the criteria under paragraph 64(c) of CEPA as it is entering or may enter the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health. It is also concluded that Basic Violet 3, Pigment Blue 61, Basic Violet 4, Basic Blue 7, and Brilliant Blue FCF do not meet the criteria under paragraph 64(c) of CEPA as they are 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.

Overall conclusion

Therefore, it is concluded that Basic Violet 3, Malachite Green, Basic Violet 4, and Basic Blue 7 meet one or more of the criteria set out in section 64 of CEPA. It is concluded that Pigment Blue 61 and Brilliant Blue FCF do not meet any of the criteria set out in section 64 of CEPA. It is also concluded that Basic Violet 3, Malachite Green, Basic Violet 4, and Basic Blue 7 meet the persistence criteria but not the bioaccumulation criteria as set out in the Persistence and Bioaccumulation Regulations of CEPA.

The screening assessment and the risk management approach document for these substances are available on the Canada.ca (Chemical Substances) website.

Pursuant to section 68 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of 2-propanol, 1-chloro-, phosphate (3:1), hereinafter referred to as TCPP, Chemical Abstracts Service Registry Number (CAS RN) 13674-84-5, and of 2-propanol, 1,3-dichloro-, phosphate (3:1), hereinafter referred to as TDCPP, CAS RN 13674-87-8. TCPP and TDCPP are part of the Certain Organic Flame Retardants (OFR) Substance Grouping, which includes 10 organic substances having the following similar function: application to materials to slow the ignition and spread of fire. These two substances were identified as a priority for assessment based on other human health concerns. A draft screening assessment of TCPP and TDCPP was published in October 2016. Significant new information subsequently became available regarding exposure to products available to consumers, specifically foam products containing flame retardants such as TCPP and TDCPP. As a result, the draft assessment was updated and is presented here.

TCPP and TDCPP are discrete organic chemicals that do not occur naturally in the environment. According to information identified from a survey issued under section 71 of CEPA, there is no manufacturing of either TCPP or TDCPP in Canada. Both substances were predominantly imported into Canada as pure substances or in manufactured items. The total import volumes in 2011 ranged from 1 000 000 to 10 000 000 kg of TCPP, and 100 000 to 1 000 000 kg of TDCPP.

TCPP is used as an additive flame retardant for manufacturing of building or construction materials in Canada (e.g. polyurethane spray foam insulation), and is contained in imported products of polyurethane spray foam insulation with the same functional use. TCPP is also imported into Canada in manufactured items containing flexible polyurethane foam (e.g. in upholstered furniture and mattresses) and as a textile waterproofing spray intended for consumer use. Available information indicates the potential for migration of flame retardants from foam objects.

TDCPP is used as an additive flame retardant in the manufacturing of flexible polyurethane foam in Canada (used in manufactured items such as upholstered furniture and mattresses). The substance is imported as a pure substance and in commercial products and products available to consumers with the same functional use.

TCPP is highly soluble in water and has a low octanol–water partition coefficient, while TDCPP possesses moderate water solubility and octanol–water partition coefficient. Both substances have a low vapour pressure and do not dissociate in water. Empirical studies indicate that neither substance is rapidly biodegradable. Both substances are considered to be very stable in water, sediment and soil, but not in air (gas phase). Based on findings from environmental sampling studies, TCPP and TDCPP have been found to be associated with particulates in air where they are considered to be very persistent. Both substances have been detected in air samples over the Arctic areas in Canada and Europe and are considered to have potential for long-range transport when adsorbed to aerosols.

Potential environmental releases of TCPP and TDCPP are from industrial activities (during their blending with a polyol) and from use of commercial products and products available to consumers. Releases from industrial activities are expected to primarily enter water via wastewater treatment systems. Based on physical and chemical properties, TCPP will partition to water, with insignificant amounts partitioning to sediments. On the other hand, TDCPP may be found in both sediment and water to some extent. Unlike TCPP, which is expected to remain predominantly dissolved in effluents, TDCPP, given its greater propensity to adsorb to solids, is likely to be found adsorbed to wastewater treatment system biosolids, which ultimately may be applied to soils. Emissions from manufactured items, commercial products, and products available to consumers are expected to enter the environment through air or dust, and ultimately settle in surface water and soil. However, it is expected that releases to the environment via this route are minimal and diffuse.

As would be expected based on the physical and chemical properties of TCPP and TDCPP, laboratory studies have reported low bioconcentration factors and rapid metabolism for these two substances, indicating that both substances have a limited potential to accumulate in aquatic biota. Significant exposure in higher trophic level organisms through the food chain is not expected for TCPP and TDCPP. Rapid excretion of biotransformation products in the mammalian studies suggests that metabolites are also unlikely to bioaccumulate.

Empirical ecotoxicity data have been identified for both substances. TCPP has demonstrated moderate toxicity to aquatic organisms and terrestrial plants, while TDCPP has shown considerably higher toxicity to aquatic organisms, including effects on the endocrine system in fish. Additional sublethal effects (i.e. neurotoxicity and genetic effects in birds) are also noted in both in vivo and in vitro studies. Data for endpoints from in vitro studies that show linkage to organism-level effects have been considered in the risk assessment for these two substances.

Considering the environmental fate and available toxicity data for these two substances, risk quotient analyses were conducted in the aquatic compartment for TCPP, and in the aquatic, sediment and soil compartments for TDCPP. Outcomes from the risk quotient analyses indicate that the risk associated with exposure of organisms to these two substances due to releases from industrial uses and products available to consumers is low at current predicted levels of release.

Considering all available lines of evidence presented in this updated draft screening assessment, there is low risk of harm to the environment from TCPP or TDCPP. It is therefore proposed to conclude that TCPP and TDCPP do not meet the criteria under paragraph 64(a) or (b) of CEPA, as they are 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.

On the basis of available information on concentrations in environmental media and results from a survey under section 71 of CEPA, the general population is expected to be exposed to TCPP and TDCPP from environmental media (air, water, dust), from food and during the use of products available to consumers containing this substance (i.e. in products such as spray foam and waterproofing products, and manufactured items such as foam-containing furniture and mattresses).

On the basis of the available information on health effects of TCPP, the critical effects for characterization of risk to human health are reproductive and developmental effects.

The margin of exposure between estimates of exposure to TCPP from environmental media (air, water, dust) and food (including breast milk) as well as use of spray insulation foam or sealant and waterproofing sprays, and the critical effect levels are considered to be adequate to address uncertainties in the health effects and exposure databases. The margins of exposure between estimates of exposure resulting from prolonged skin contact with certain manufactured items containing TCPP, such as foam-containing upholstered furniture and mattresses, and the critical effect levels are considered potentially inadequate to account for uncertainties in the exposure and health effect databases.

On the basis of available information and classifications by other international regulatory agencies, critical effects for characterization of the risk to human health from exposure to TDCPP are carcinogenicity and non-cancer effects on the kidneys and testes. Tumours were observed in multiple organ sites, including kidney and liver in both sexes, testes (in males) and adrenal gland (in females) in a two-year carcinogenicity study in rats. Results of genotoxicity tests were mixed in vitro and mostly negative in vivo.

The margins of exposure between estimates of exposure to TDCPP from environmental media (air, water, dust) and food (including breast milk), and the critical effect levels for cancer and non-cancer effects are considered to be adequate to address uncertainties in the health effects and exposure databases. The margins of exposure between estimates of exposure resulting from prolonged skin contact with manufactured items containing TDCPP, such as foam-containing upholstered furniture and mattresses, and the critical effect levels for cancer and non-cancer effects are considered potentially inadequate to account for uncertainties in the exposure and health effects databases.

On the basis of the information presented in this updated draft screening assessment, it is proposed to conclude that TCPP and TDCPP meet the criteria under paragraph 64(c) of CEPA, as they are entering or may enter 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 overall conclusion

It is therefore proposed to conclude that TCPP and TDCPP meet one or more of the criteria set out in section 64 of CEPA. It is also proposed that TCPP and TDCPP meet the persistence criteria but not the bioaccumulation criteria as set out in the Persistence and Bioaccumulation Regulations of CEPA.

The draft screening assessment and the risk management scope document for these substances are available on the Canada.ca (Chemical Substances) website.
