The general term for describing the accumulation of chemicals in the tissue of organisms. The chemicals that bioaccumulate are most often organic chemicals that are very soluble in fat and lipids and are slow to degrade. Usually used in reference to aquatic organisms, bioaccumulation occurs from exposure to contaminated water (e.g., gill uptake by fish) or by consuming food that has accumulated the chemical (e.g., food chain/web transfer). Bioaccumulation of chemicals in fish has resulted in public health consumption advisories in some areas, and has affected the health of certain fish-eating wildlife including eagles, cormorants, terns, and mink.
