Abstract : This note provides information regarding the potential extent of biomagnification (the tendency for contaminant concentrations in animal tissues to increase through successively higher trophic levels) of contaminants in aquatic food chains resulting from the open-water disposal of contaminated dredged material. The note also provides a technically sound perspective and offers general technical guidance on assessing the environmental importance of biomagnification in aquatic food chains as a result of open-water disposal of contaminated dredged material. It does not consider biomagnification in nonaquatic organisms. pg1. JMD
