Abstract
Genotoxic effects were evaluated in the somatic and gonadal cells of five bivalve and gastropod mollusc species inhabiting various sites of Klaipėda port area, differing by ecotoxic impacts. Aneuploidy, polyploidy of cells, meiotic injures, centromere dissociation and fragmented polyploid nuclei were assessed as cytogenetic disturbances. The highest level of environmental genotoxicity was observed in the cells of Lymnaea ovata snails inhabiting Malkų Bay in 1995 and 1996. Dredging and removal of contamined sediments from Malkų Bay resulted in marked decrease of cytogenetic damage in molluscs, which were studied in 1997 and 1998. In 1997 the aneugenic effects were more frequent in the tissues of Bithynia tentaculata from Smeltė River than those collected from Malkų Bay and Klaipėda passage. The level of cytogenetic damage in molluscs from Vilhelmo Channel was increasing from 1995 to 1998.
