Lipid Profile of the Mussels Lymnaea stagnalis (Mollusca: Gastropoda) in Lakes with Different Degrees of Anthropogenic Pollution

Dependence in water bodies between the degree of anthropogenic impact and the composition of lipids and fatty acids (FA) separately liver, foot and body of L. stagnalis has been examined. The lake located within the city limits is susceptible to various types of pollution, the lake in the national park zone is clean. The ecological condition of the different lakes probably influenced the composition and content of total lipids and fatty acids of L. stagnalis. The highest lipids have been noted in the liver of the snail. In the body, liver and leg of the species the lipids phosphatidylcholine and phosphatidylethanolamine dominate, the FA — polyunsaturated acids. The change of the lipid and FA content of the L. stagnalis in lakes is probably due to the high concentration of organic compounds, heavy metals.
