Abstract
Purpose. Identification and analysis of the content of organochlorine pesticides (OCP) in organs and tissues of benthivorous and predatory fish species of the Kiliya delta of the Danube (Eastern mouth) and their comparison with previous years. Methodology. The analysis of the samples of aquatic organisms for the content of residual organochlorine pesticides was carried out by gas-liquid chromatography (GLH) based on a unified methodology. The chromatographic analysis was carried out on the gas chromatograph "Color 5" with electron capture detector at the Institute of Hydrobiology of the National Academy of Sciences of Ukraine. Findings. The effect of stable organochlorine pesticides on aquatic organisms is characterized by marked persistence in the environment and by high ability for migration and accumulation on different levels of food chains in aquatic ecosystems. The continuous presence of OCP in all investigated organs and tissues of selected species with the presence of a certain amount of fat and consequently, the fixation of residual organochlorine pesticides. Among benthivorous fishes, the content of OCP in organs and tissues (total) is as follows: vimba → roach → wild carp → bream → gibel carp. Among the predators: asp → perch → European catfish → pikeperch. Originality. Recently, a significant number of scientists all around the world returns to the problem of the accumulation and distribution (redistribution) of OCP in the components of aquatic ecosystems. This is associated with certain threats to the environment and human health, that could lead to negative consequences as a result of the consumption of fish as the highest trophic level in fresh waters of Ukraine. Practical value. The obtained data indicate that the major commercial fish species of the Kiliya delta of the Danube river contains residual quantities of pesticides. This indicates to the need for continuous hygienic and toxicological monitoring of fish caught and sold. There is a tendency that smaller amounts of OCP are accumulated in less active species benthivorous (bream, gibel carp) compared to active ones (vimba, roach, wild carp), and these patterns are confirmed to the current study.
