Environment Canada recently released the final screening assessments for 18 substances assessed as part of Batch 4 of the federal government’s Chemicals Management Plan. Under this plan, the government has been performing scientific assessments of, and undertaking consultations with respect to, substances present in Canada that have not been previously assessed, in order to develop appropriate riskmanagement responses. Of the 18 Batch 4 substances, one substance, benzenamine, was found to pose a risk to the environment and was recommended for “virtual elimination” under the Canadian Environmental Protection Act, 1999 (CEPA). Two other substances, dimethyl sulfate and diethyl sulfate, were found to pose a risk to human health. The federal ministers of Environment and Health recommended that all three substances be added to CEPA’s list of toxic substances. However, the government is accepting comments on the risk-management approaches for the Batch 4 substances until September 29, 2009.
