Sister Chromatid Exchange in a Marine Polychaete Exposed to a Contaminated Harbor Sediment

摘要

The report evaluates the use of SCE to measure DNA-damaging activity associated with contaminated dredged material. The primary objectives were to test the applicability of the SCE technique and to field verify any responses observed in the laboratory. The SCE technique was applied to Nephtys incisa, an infaunal polychaete dominant in the benthic community of Long Island Sound. The SCE response was measured in N. incisa exposed in the laboratory to suspended and bedded phases of sediments dredged in Black Rock Harbor (BRH), Connecticut, and in N. incisa sampled along a transect of stations at the Central Long Island Sound (CLIS) site where BRH material was disposed.
