Sanitary and hygienic characteristics of potassium stearate as a source of anthropogenic pollution of water reservoirs

Monitoring of surface water quality indicates deterio­ration its due to anthropogenic pollution. Among them, potassium stearate (PS) occupies a prominent place. The purpose the study is substantiate regulations in reservoirs on basis sanitary and hygienic assessment stearate, stability transformation, impact organoleptic properties water, condition, self-cleaning processes condition reservoirs. Research methods – bibliographic, analytical, statistical, hygienic. It was found that average effective concentration PS by taste for threshold sensation (1 point) at level 6.43 mg/dm3. intensity 1-2 points maintained 10 days. Potassium hydrolyzing non-chlorinating substance. As result assessing self-purification from organic pollution observing dynamics oxidation, dissolved oxygen biochemical demand (BOD), ammonification, nitro- nitrification, it limiting BOD. On inactive concentrations all signs harmfulness one allows recommending maximum permissible 0.25 indicator harm sanitary. Comprehensive obtained expe­rimental calculated data rationing general open classifing as 4th class danger (practically non-toxic substances).
