N1 - Toxic Elements in Natural Waters of the Novosibirsk Urban Agglomeration: Distribution, Background, Anomalies / A. V. Chernykh, D. A. Novikov, A. A. Maksimova [et al.] // Chemistry for Sustainable Development. – 2023. – Vol. 31, No. 4. – P. 452-464. – DOI 10.15372/CSD2023490. The field works were carried out with financial support from the Ministry of Science and Higher Education of the Russian Federation under Project No. FWZZ-2022-0014, analytical works aimed at the studies of the chemical composition of groundwaters, substantiation of the geochemical background and anomalies were supported within Project No. 22-17-20029 by the Russian Science Foundation and by the Government of the Novosibirsk Region.

N2 - The distribution of the 1st hazard class substances and trace elements in the natural waters of the Novosibirsk urban agglomeration is investigated. A substantial role in water pollution is played in the study area not only by a large number of vehicles but also by industrial enterprises. The composition of natural waters is determined as mainly hydrocarbonate calcium and hydrocarbonate calcium-magnesium, with total dissolved solids varying from 127 to 910 mg/dm3, and silicon concentration 0.14-11.61 mg/dm3. The geochemical setting changes from reducing (Eh -164.3 mV) to oxidizing (Eh 442.1 mV), pH 6.9-8.8 with O2(sol.) content 0.48-20.28 mg/dm3. Within the city of Novosibirsk, excesses of background values for 33 elements were revealed; the concentrations of the first hazard class substances are, mg/dm3: Be (6.4•10-6)-(1.4•10-4), As 0.0003-0.26, Hg (8.33•10-7)-(2.3•10-4), Tl (6.2•10-7)-(8.2•10-5), U (1.3•10-5)-0.21. The activity of radon, established in the natural waters of the city of Novosibirsk, varies from 1 to 1570 Bq/dm3. The waters under active anthropogenic load are mainly the river waters of the Inya, the Eltsovka the 2nd, the Plyushchikha, the Eltsovka, the Kamyshenka, and the Ob. In groundwater samples, excesses over the actual normative documents and maximum permissible levels were revealed in the well in Kirov settlement (Mn - by a factor of 14, Fe - 10, As - 5), and in the Topol Gardeners Non-Commercial Partnership (Mn - by a factor of 59, Fe - 94, and As - 27).
