CANADA - The Canadian government has started a public consultation regarding its proposed approach for cumulative risk assessment (CRA), both human health and ecological, from combined exposure to 14 phthalates. Selection of these phthalate substances for action is based on the categorization process completed in 2006.
The proposed approach documents:
- Key considerations for risk assessments
- Summary of current international initiatives for the cumulative risk assessment of phthalates
- Summary of the "approaches considered to be most relevant for the assessment of cumulative risk from combined exposures to certain phthalates under the Chemicals Management Plan (CMP)"
Since there is a potential that some phthalates may have common health effects of concern, Health Canada has addressed the possibility for cumulative risk from combined exposure to these substances by expanding the scope of the grouping from by adding an extra 14 substances. These include the following, which have been assessed under the Canadian Environmental Protection Act (CEPA):
- Dibutyl phthalate (DBP)
- Butyl benzyl phthalate (BBP)
- Diethyl hexyl phthalate (DEHP)
Deadline for submission of comments is September 30, 2015. The draft screening assessments for the substances are expected to be released in the summer of 2016, and the final screening assessments and cumulative risks in 2017.
