Raincoast Conservation Foundation reports that a new Simon Fraser University study found juvenile Chinook salmon in the Lower Fraser River estuary are being exposed to a complex mix of contaminants while they feed and grow in critical habitat.

Researchers detected hundreds of organic contaminants in water and fish tissue samples, including pharmaceuticals, personal care products, pesticides, flame retardants, industrial chemicals, caffeine, and cocaine. Sixteen contaminants were identified as priorities because they may pose risks to Chinook salmon and other aquatic life.

The findings add another concern for Fraser River Chinook, many of which are already under pressure from habitat loss, climate change, rising water temperatures, pathogen exposure, and other stressors. The study reinforces the need to better protect salmon habitat and reduce human-caused pressures during critical stages of the salmon lifecycle.
