Ecological-toxicological Assessment of the Desna River and Adjacent Floodplain Lakes (within the Chernigiv Region) in Terms of Pesticides Content in Fish Liver

摘要

According to the study of accumulation of pesticides in fish liver in the Desna River, lakes Volzhyn and Cherneche (in the territory of the Chernigiv region) these reservoirs can be considered as contaminated. An actual level of pesticide contamination of these water bodies has a strong negative impact on the fish liver. Accumulation was more intensive in spring, especially in predatory fish species (pike, pikeperch ruff, sabrefish). Among the pesticides glyphosate, imidacloprid, carbendazim, metribuzin and bentazon were the most essential. Detecting pesticides in fishes is a signal for updating the monitoring in order to prevent negative effects on the ecosystems.
