Fluctuations of Annual Precipitation and Water Resources Quality in Ukraine

Abstract

The article focuses on examining the influence of fluctuations in annual precipitation amount on the quality of surface waters. Water quality was estimated with data on BOD, COD and phosphate-ion concentration within five selected regions of Ukraine. Analysis of the precipitation data (1991-2010) showed different regional trends. Using the statistics, determination of the interconnection between precipitation amount and water resources quality were done. The obtained regularities and associated uncertainties can be used for prediction of changes in water resource quality and as a guide for future adaptation to possible climate change.

Investigation of the Dispersed-Phase Distribution of Organochlorine Pesticides, Polychlorinated Biphenyls and Polycyclic Aromatic Hydrocarbons in Natural Water Systems

“…22 The specified COD and BOD values coincide with the values given for Ukrainian water systems in paper. 23 Fig. 5 shows the dependence of the total watersoluble fraction of OCPs, PCBs, and PAHs on the COD value in water.…”

Quantification of nitrate fluxes to groundwater and rivers from different land use types

“…The studied region is a relatively water scarce one and has very limited local runoff, with substantial part of water supply provided by water translocation from other Ukraine's river basins via artificial canals . Additionally, the region is considered to be influenced by climate change that results in the deterioration of water quality (Pidlisnyuk, V. et al 2016). Thus, knowledge on water contamination sources is urgently needed to secure drinking water supply, prevent the spread of water-related diseases and protect natural aquatic systems (Canter, L.W.…”
