Abstract : This technical note reports and compares initial results of six genotoxicity bioassays applied to dredged sediments and describes progress toward development of a testing protocol to aid in regulatory decisionmaking when genotoxic chemicals are an issue of concern. The Long-term Effects of Dredging Operations Program work unit Genotoxicity of contaminated Dredged Material was initiated in fiscal year 1990 to develop methods for assessing the genotoxic potential of dredged sediments. The impetus driving this new research and development effort was specific regulatory language in section 103 of the Ocean Dumping Act (Marine Protection, Research, and Sanctuaries Act (MPRsA) of 1972) prohibiting the open-water discharge of mutagenic, carcinogenic, or teratogenic substances in other than trace amounts, and language less specific but of similar intent in section 404 of the Clean Water Act (CWA). pg1.
