Accumulation of Heavy Metals by Pond Snail Lymnaea stagnalis as Index of Pollution of Small Water Bodies

D. V. Lukashov
Kyiv National University Kyiv, Ukraine

ABSTRACT

Content of heavy metals in mollusks' body was suggested to be used as a marker of their biological availability and as a parameter of chemical pollution of the aquatic ecosystems. Upper background content of metals in organism was used as a quantitative criterion of pollution degree. This parameter reflects excess enter of metal into the snail organism. The pond snail Lymnaea stagnalis L., common species of freshwater gastropods, was used for investigation of the small water bodies' pollution. In the water bodies of western and eastern regions of Ukraine background concentrations of Cd, Cu and Cr in the soft tissues of the snail were exceeded.
