Copper in Surface Waters of Ukraine: Content, Forms of Occurrence, and Regularities of Migration

Results of long-term investigations of Cu(II) in various water bodies of Ukraine (reservoirs, rivers, and lakes) are given in the paper. It has been found that the content of Cu(II) varies over a wide range − from 3.6 to 62.5 µg/L. In the Dnieper reservoirs, the concentration of Cu(II) increases downstream of the Kiev Reservoir, which is conditioned by the influence of anthropogenic load. The lowest content of Cu(II) is observed in the rivers of the Pripyat River basin. In the studied water bodies, copper migrates mainly in the dissolved state. However, in the water bodies characterized by the formation of anaerobic zones with the presence of H2S in the near-bottom layer of water the content of the suspended form of copper can be higher than that of the dissolved form. The content of the labile fraction of Cu(II), as potentially toxic, accounts for 0.4−8.5 µg/L (7.2−35.0% Cudissolved). The data on the distribution of Cu(II) among its complex compounds with dissolved organic matter are discussed in the paper. It has been shown that the anionic complexes of Cu(II) with humic substances predominate (44.8−78.2% Cudissolved). Results of the study of the molecular-mass distribution of the anionic complexes of Cu(II) are also discussed in the paper.
