| description | Relevance. Rare earth elements (REE) and parameters of the basic salt composition (BSC) are the indicators of the ecological state of river waters and they can be used for water subjects monitoring system. The aim of the research is a comprehensive study of the REE and BSC to identify the factors determining the anthropogenic load on the basins of the rivers of southern Primorye. Research methods. Concentration of major ions (Cl-, SO[2- 4], Na+, K+, Ca2+, Mg2+) were analyzed by ion chromatography (Shimadzu LC-20A), and REE were studied by mass spectrometry with an inductively coupled plasma (Thermo Finnigan Element 2). pH was measured by potentiometric method, total alkalinity was analyzed by direct titration by Bruyevich method, and total mineralization ([sigma]n) is the total concentration of major ions. Results. Seasonal hydrochemical study of the BSC of southern Primorye rivers showed that river water is low-mineralized, average annual [sigma]n does not exceed 100-150 mg/l. the investigation detected the significant increase in a part of sulfate ions in rivers Knevichanka, Razdolnaya and Artemovka during the spring flood, which is associated with fuel combustion in winter season, and household sewage. Regional level of total concentration of dissolved REE in the studied surface water varies from 0,16 to 2,72 mg/l. REE interval fluctuations in the water of some rivers is from 0,20 to 0,56 mg/l. High concentration of rare earth elements and dissolved salts in surface water of Razdolnaya, Artemovka, Knevichanka and Shkotovka rivers is associated with anthropogenic load on the basins of these rivers. |
