Chemical composition and water quality of some rivers of the sverdlovsk oblast (Ural, Russia)
The water quality of a river is very important as it is using for drinking and domestic purposes, agriculture and aquatic life including fish and fish farming. The concentration of the major ions (Cl-, SO42-, K+, Na+, Mg2+, Ca2+), nitrogen and phosphorus compounds (NH4+, NO2-, NO3-, HPO42-), ions Ba2+, Sr2+ , Heavy metals and trace elements (Ba2+, Fe, Cd, Co, Si, Mn, Cu, Ni, Pb, Sr2+, F-, Zn), concentration was determined. The results showed thatgeneral indicators, according to the chromaticity value, samples of different rivers differed very strongly. According to the value of mineralization, the water of all samples was fresh. According to the cationic composition, 7 samples had calcium type and one (Pozarishka) had a mixed type. Also, the content of organic matter in the samples was generally significant. The lowest oxidation values were recorded in the samples of the Ufa river network (Nos. 6 and 7), The highest in the water of Iset river. The concentration of most elements in the water exceeded the standard values.
