Contaminants in the environment have posed challenges for decades, but in the past several years, emerging contaminants like pharmaceuticals, fire retardants and others have prompted concern about their impact on fish and wildlife. Some impacts include feminization of male fish, irregular courtship and nest-guarding behavior, decrease in predator-escape response, and declines in prey species and sport fish populations.
