Chemical Cocktail in Fraser River Threatens Salmon, Whales
Description
Researchers in British Columbia discovered over 200 contaminants in the Lower Fraser River estuary, including cocaine, antidepressants, caffeine, and flame retardants. Sixteen of these were flagged as priority contaminants, potentially harming aquatic life, particularly chinook salmon, a major food source for endangered southern resident killer whales. Scientists plan to study the impact of these contaminants on salmon health, as they were tested individually, not as a complex mixture. The Fraser Rivers fast flow could concentrate contaminants in slower-moving creeks, threatening both species survival.
