Development of a methodological approach for determination of environmental risks of water bodies pollution across industrially developed territories (as exemplified by the rivers of City of Kharkiv)

The study’s relevance consists in the need to determine prospects for achieving a good environmental condition of Ukrainian water bodies accordance with Water Framework Directive European Union on establishing framework Community's activities field policies. question ability achieve set goals is related assessment risks surface pollution by chemical substances. purpose research develop new approaches identification rivers' across industrially developed territories. study was carried out using data hydrochemical observations Lopan and Kharkiv rivers. rivers are located inside City exposed both industrial discharges municipal wastes. work based application probabilistic approach aimed at determining quantitative indicators statistical distribution such indicators. scientific novelty offering method modified indices risk specifically biogenic substances heavy metals. This allows evaluating ensuring despite from various sources. results presenting building scale qualitative their consequences. It relies upon semantical match gradations aquatic environment quality contamination that covers showed close relationship between indices. revealed dependencies made it possible harmonize semantic gradation scales scales. Practical methodology implies only calculation index metals or observation zone corresponding situation according scale. proposed recommended use when territories different countries.
