- Аннотация: Coastal cities are major centers of economic activity, which at the same time has negative consequences for theenvironment. The present study aimed to determine the concentrations and sources of PTEs in the urban soils ofTaganrog, as well as to assess the ecological and human health risks. A total of 47 urban and 5 backgroundtopsoils samples were analyzed by ICP-MS and ICP-AES. A significant excess of Cu, Zn, and Sb was noted in urbansoils compared to the upper continental crust and average world-soil (1.7–2.9 times). Statistical analysis showedthat the elements in soils were of geogenic, mixed and anthropogenic origin. According to the single pollutionindex (PI), the greatest danger of soil pollution was represented by anthropogenic elements, namely Cu, W, Pb,Zn, Cd, and Sn, the levels of which were increased in residential and industrial areas. The median contents of As,Mn, Cr, Sr, Mo, Sb, Cu, W, Pb, and Zn were 1.1–2.1 times higher, while Cd and Sn were 2.5 folds higher in theurban soils compared to the background ones. The total pollution index (ZC) showed that only 15% of the soilshad high level of pollution, which is typical for the industrial areas. Overall ecological risks were negligible orlow in 92% of soils, and were mainly due to elevated levels of Cu, Zn, As, and Pb. Non-carcinogenic risks tohumans were mainly related to exposure to La and Pb. The hazard index (HI) values for all PTEs were less thanten, indicating that overall non-carcinogenic risk for adults and children was low-to-moderate and, moderate,respectively. The total carcinogenic risk (TCR) exceeded threshold and corresponded to low risk, with Pb, As, andCo being the most important contributors. Thus, the industrial activities of Taganrog is the main source ofpriority pollutants.
