Evaluation of Economic Consequences of Anthropogenic Pollution of Water Objects (On the Example of Vyalivsky Reservoir
Abstract
Purpose. Eco-toxicological assessment of surface water and bottom sediments of Vyalivsky reservoir and based on the results of experimental studies on the influence of anthropogenic pollution on the livelihoods of fodder organisms, to calculate the damage caused to water bodies by the indicator of decrease of bio-productivity on the example of Vyalivsky reservoir. Methods. Biotesting of water samples was carried out using zooplankton (Ceriodaphnia affinis Lilljeborg) and zoobenthos - insect larvae (Chironomus dorsalis Meig.) as a test facility for fodder organisms for fish. For estimation of losses caused for Vyalivsky reservoir we used methodology for calculating the amount of compensation for damage caused to the fishery as a result of violations of legislation on the protection, use and reproduction of aquatic biological resources. Results According to the results of determination of the toxicity of surface waters and bottom sediments, damages caused to Vyalivsky reservoir were calculated on the indicator of decrease in fish productivity as a result of the death of fodder organisms for fish. Conclusions The toxicological studies of surface waters and bottom sediments of Vyalivsky reservoir have revealed the presence of toxic properties of the investigated objects, which may result in the reduction of biomass of fodder organisms of aboriginal species of fish in a given reservoir.
