Petruk A. Assessment of aquatic ecosystems on a set of environmental indicators (for example cooling pond HAES and White Lake).

Object of research: Natural and anthropogenic changes occurring in aquatic ecosystems different purpose. Objective: was to assess the condition of aquatic ecosystems of natural and artificial origin on a set of environmental indicators and to identify the effects of anthropogenic impact on the studied aquatic ecosystems. Methods: during research used theory, application methods, and the method of correlation analysis. Scientific novelty: First found operating conditions of aquatic ecosystems of different types of water located in the thirty-kilometer zone from the NPP, traced the trend in the quality of their surface water and the estimation of biological productivity of primary and secondary products of the studied reservoirs, which are a result of anthropogenic pressure due to high content of toxicants, namely heavy metals and radionuclides. The regularities of distribution of toxins in the food chain of reservoirs 2 nd and 4 th grade quality. First performed toxicological and radiological assessment of the quality of fish, which is formed during operation biomelioratyvnoyi reservoir and recreational lake load. Degree of implementation: The mathematical model of migration of heavy metals and radionuclides in aquatic ecosystems, which allow to obtain predictive calculations of these toxicants in aquatic ecosystems with respect to their values in water. Research results incorporated into the teacher's book "A comprehensive environmental assessment of natural and artificial hidroekosystem different purpose". Scope: higher education for majors "Water Bioresources" and "Ecology and Environment"
