Each of the 25 substances on the second Priority Substances List (PSL2) is being assessed to determine the risks it poses to the environment and human health.

Experts from various fields are invited by Environment Canada to participate actively in the assessment process. They form an Environmental Resource Group, which can include scientific and technical experts from all levels of government, industry, academia, environmental groups, and other interested parties.

An Environmental Risk Assessment for each PSL2 substance is being conducted by Environment Canada. Human health risk assessments for each substance are being carried out by Health Canada. Results from both assessments are used to determine if the substance should be declared "toxic" under the Canadian Environmental Protection Act, 1999 (CEPA 1999).

Once a draft report has been prepared, it will be made available for a 60-day public comment period. Following consideration of comments received, the Assessment Report will be revised as appropriate and published with final conclusions as to whether or not the substance is considered to be "toxic" as defined in CEPA 1999.
