The assessment will inform the development of a proposed plan for managing chemicals, which will be published for consultation this summer.
OTTAWA — The federal government has agreed to prioritize environmental assessment for a chemical used in tire rubber that has been linked to the deaths of Pacific salmon.
The letter, dated April 30, says the review will determine whether the substance is toxic or capable of becoming toxic under Canada's environmental protection law. The request from three British Columbia-based groups in February cites a study published in Science, a top academic journal, which found the chemical produces a breakdown substance that's lethal for coho salmon in particular.
The researchers behind the 2020 study concluded that the substance, 6PPD-quinone, was responsible for previously unexplained coho deaths spanning decades in Seattle-area watersheds.
