RESUMO

Results of long-term investigations of Pb(II) in surface water bodies (rivers, reservoirs, and small lakes) of Ukraine, and also data on its content in surface waters of other countries of the world, have been generalized in the paper. It has been shown that in water bodies and watercourses of Ukraine the maximal concentration of this chemical element was observed in the late 1980s. With time, it decreased with decreasing the intensity of industrial production, and also with decreasing the influence of anthropogenic factor. In surface waters of other countries of the world, the content of Pb(II) essentially differs. Some water bodies are clean, whereas others are heavily polluted by the compounds of lead, which is conditioned by their dislocation near metallurgic complexes, or by their contamination by sewage. Relationship was established between the suspended and dissolved forms of Pb(II). It has been found that the suspended form of lead prevails in river waters, whereas its content depends on the mass of suspended matter. The content of the dissolved forms of Pb(II) is also discussed. It has been found that the contribution of its labile fraction (potentially bioavailable and toxic) is not more than 2.4-11.2% Pbdis. The major portion of Pbdis was found in the composition of its complex compounds with dissolved organic matter. Humic substances are of considerable importance in the process of complexation. In small water bodies, carbohydrates are also involved in the process of Pb(II) binding. The compounds with the molecular mass ≤ 2.0 kDa prevail among anionic complexes of Pb(II).
