The bioaccumulation of endocrine disruptors, persistent organic chemicals and other compounds of high environmental impact has become of increasing interest in most recent environmental research, risk analysis and toxicology. This volume gives an up-to-date overview and introduces the reader to the new concept of internal effect concentration linking bioaccumulation and biomagnification in the food chain to ecotoxicology and risk assessment.With contributions by numerous expertsH.J.
