Abstract <p>This article presents the results of a study of the heavy metal content in soil and paint samples collected at scientific stations in Belarus (Mount Vechernyaya) and Russia (Bellingshausen, Mirny, Progress, and Novolazarevskaya), as well as at the Molodezhnaya and Druzhnaya-4 Russian field bases.

It was found that the content of lead in previously used paints in 76% of cases, zinc in 60% of cases, and chromium in 47% of cases exceeded 1000 mg/kg of dry matter.

Abstract

This article presents the results of a study of the heavy metal content in soil and paint samples collected at scientific stations in Belarus (Mount Vechernyaya) and Russia (Bellingshausen, Mirny, Progress, and Novolazarevskaya), as well as at the Molodezhnaya and Druzhnaya-4 Russian field bases. The studies were carried out in the summer Antarctic seasons of 2021/22 and 2022/23. Paint samples were collected from old painted surfaces of buildings and infrastructure elements and abandoned vehicles. Soil samples were collected near buildings from a depth of 0–10 or 0–15 cm. The content of heavy metals (Cd, Cr, Cu, Pb, Ni, Zn) in solid substrate samples was determined using atomic absorption spectrometry. It was found that the content of lead in previously used paints in 76% of cases, zinc in 60% of cases, and chromium in 47% of cases exceeded 1000 mg/kg of dry matter. High concentrations of cadmium (more than 10 mg/kg) were recorded in 20% of cases. A wide range of measured concentrations of most heavy metals was revealed in soil samples near painted surfaces, with the maximum recorded lead content. The condition of painted surfaces at the research stations, destruction of coatings, and paint removal by strong winds are discussed. It is shown that local high concentrations of heavy metals in Antarctic soils (“hot spots”) may be caused by their leaching from painted surfaces and dispersion of paint fragments. The need for special studies to quantitatively assess the impact of paint coatings on the content of heavy metals in the soils of Antarctic oases is substantiated.
