Contaminants such as polychlorinated biphenyls and organochlorine pesticides are among the most environmentally persistent pollutants. Although the more problematic of these chemicals are not produced in the United States, the compounds can be transported to Alaskan watersheds from remote locations via winds, currents, and through carcasses of returning salmon. Concentrations of total polychlorinated biphenyls and 23 pesticides eluted from passive samplers deployed for 30 days in the Kenai River were near or below 10 ppb, despite 30-day deployments of the strips. Concentrations of these compounds in both eggs and muscle tissue from returning Chinook salmon were also below 10 ppb and did not differ with respect to...
