Abstract
The relationship between the ecological conditions in water bodies experiencing varying degrees of anthropogenic impact and the composition of total lipids and fatty acids (FAs) of individual organs and tissues (liver and foot) and the whole body of the freshwater snail Limnaea stagnalis has been studied. The lake located within the city limits is subject to various types of pollution, and the lake located within a specially protected natural area is clean. The composition and content of total lipids and fatty acids in mollusks changes depending on the ecological conditions in the lakes. Their maximum content was detected in the digestive gland. The dominant lipids in the organs and tissues of the mollusks in the studied lakes are phosphatidylcholine and phosphatidylethanolamine, and polyunsaturated acids predominate in the FA composition. The changes in the content of lipids and FAs of L. stagnalis are probably due to the high concentrations of organic compounds and heavy metals.
