Identification of Pollutant Clusters in Trade Effluent in Kuzbass
The entropy analysis is used to study composition of trade effluent in the Kemerovo Region. A number of clusters of pollutants are detected in organic and metal-bearing water solutions (aniline, fats, oils, oil products, phenols, synthetic surfactants, silicon, fluorine, chromium, cyanides, aluminium, vanadium, iron, magnesium, copper, nickel, lead, zinc, nitrates, nitrites, ammonia nitrogen). The evolution of population of the pollutants in surface water bodies in 2008-2013 is illustrated. It is found that water quality of most water bodies in the discussed mining region is beyond standard.
