Abstract

Abstract The paper presents the results of a study conducted in 2019 in which 29 rainfall water samples were collected and analyzed. The concentration of insoluble particles in rainwater was determined, and analysis of the material composition was performed by scanning electron microscopy. The content of Al, Mn, Ni, Cu, Zn, Cr, Co, As, Sr, Cd, Mo, Ba, Be, V, and Pb was determined by inductively coupled plasma mass spectrometry on a quadrupole spectrometer Agilent7500a at the P.P. Shirshov Institute of Oceanology of RAS. The highest concentrations of insoluble particles (6.5–12.2 mg/L) with the domination of the anthropogenic components in the rainwater were revealed in the samples of the summer-autumn period, while the lowest ones (1.1–3.9 mg/L), with a predominance of biogenic and mineral components were detected in the spring period. A group of heavy metals (Pb, Cd, Zn, Cu, and Ni) of anthropogenic origin was identified by calculating the enrichment factor (EF).
