An increase in the concentration of an exogenous substance in the tissues of organisms higher than surrounding ENVIRONMENT. Accumulation of such XENOBIOTICS at successively higher levels up the FOOD CHAIN is called biomagnification. Bioaccumulation of toxic chemicals (e.g., Lead and DDT) may result in CHEMICALLY-INDUCED DISORDERS.
