2008 m. Nr. 4 Cytogenetic damage in gill and gonad cells of bivalve molluscs
Cytogenetic effects were examined in gill and gonad cells of bivalves Anodonta cygnea, Unio tumidus and Dreissena polymorpha inhabiting the Lithuanian lakes Birva, Skaistis, Drūkšiai, Verkiai and the artificial Elektrėnai and Kauno marios water reservoirs. The highest level of aneugenic effects (cells with hypodiploid, hyperdiploid and polyploidy chromosome sets) was found in molluscs from contaminated artificial water reservoirs, and significantly fewer injures were detected in bivalves from the uncontaminated lakes Verkiai and Skaistis. Keywords: aneugenic effects, chromosomes, Unio, Anodonta, Dreissena |
