Abstract
Abstract Environmental status of Kam’yanske reservoir (47°55′51.6″N 33°46′08.4″E) as one of the small water bodies belonging to southeast Ukraine was investigated. The integrated environmental assessment based on the quality indices of salt content, trophic–saprobiological indicators and specific toxic water indicators of Kam’yanske reservoir are characterised as ‘satisfactory’ and ‘slightly polluted’. Defined bottom accumulation coefficient (BAC) shows continuing heavy metals enlargement in the upper layer of the bottom sediments and chronic pollution in ecosystem. The content of heavy metals in the muscles of industrial fish in the researched pond did not exceed maximal allowed concentration (MAC) for fish as food according to Ukrainian standards. Accumulation of heavy metals in fish was due to the peculiarities of their ways of nutrition and existing. The total contents of heavy metals in common carp was almost twice as large compared to other fish. The maximum accumulation rates set for fish muscles of essential elements – zinc and iron.
