Environmental Effects of Dredging: The Use of Population Modeling to Interpret Chronic Sublethal Sediment Bioassays
This technical note provides a brief introduction to population modeling and describes the application and utility of such techniques for dredged material bioassays. The use of population modeling as a source of interpretive guidance for chronic sublethal dredged material bioassays is emphasized. Current laws and regulations governing the discharge of dredged material stress the importance of assessing the chronic (long-term) sublethal effects of dredging operations. Regulations implementing section 103 of the Marine Protection, Research and Sanctuaries Act (PL 92-532) state that, 'Materials shall be deemed environmentally acceptable for ocean dumping only when . . . no significant undesirable effects will occur due either to chronic toxicity or to bioaccumulation........'. Similar language is used in regulations implementing section 404(b)(1) of the Clean Water Act (FL 92-500) which reads: 'The permitting authority shall determine in writing the potential short-term or long-term effects of a proposed discharge of dredged or fill material on the physical, chemical, and biological components of the aquatic environment.........It also stipulates that tests may be required to provide information on the effect of the discharge material on communities or populations of organisms.'.
