Miroshnikova E.P., Arinzhanov A.E. HEAVY METALS IN WATER AND BOTTOM SEDIMENTS OF THE IRIKLINSKAYA RESERVOIRRecently the volume of industrial drains in reservoirs of the Orenburg region has increased. Heavy metals in water ecosystems don't decay, are constantly redistributed on separate components and collect in hydrobionts of various trophic levels, including fishes and by that constitute danger to the person eating fishes from the polluted reservoirs. Maintenance and distribution of heavy metals in water and soil of the Iriklinsky reservoir have been investigated. Water samples were taken with a sampler of Rutner into 6 sections: Dam ples, Tanalyk-Sandusky ples, Chapaevsky ples, ples Sofinsky, Thanalakshi Sandusky Gulf and the Bay. Samples of bottom sediments were taken at channel stations from the horizon 0–10 cm of the grab. The studies observed excess of maximum permissible concentration (MPC) in water of reservoir compounds Cu — in 3–10 times, Fe — in 2–10 times, Mn — in 2–22 times, Al — in 4–5 times. Sediments of channel sites Iriklinskaya reservoir were mainly represented by grey sandy silts, organic matter content of which was 15-17 %. For bottom sediments was characterized by excessive concentrations at all the study sites only for Cu (5–6 times) and Zn (5–7 times). In addition, the recorded excess of MPC for Pb in the sediments of the river and Chapaevskaya Soundexchange Bay in 1.5 times, and Dam-site more than 5 times.Key words: heavy metals, water, sediments, reservoir.
