Abstract
The paper presents the results of studies of oil hydrocarbons contents in atmospheric precipitations in 2023 on monitoring stations in South Pre-Baikal (Irkutsk City, Listvuanka and Bol’shiye Koty settlements, Baikal Natural Biosphere Reserve). It was found out that maximal OH concentrations were observed in the precipitations of autumn and winter months, this is due both to low precipitations during that period and to increase of volume of oil-containing emissions during heating season. The degree of pollution of rain and snow waters with oil hydrocarbons according to sanitary and hygienic norms for fishery water bodies was estimated (MPC for fishery waters). An elevated content of oil hydrocarbons in the precipitations at the station Irkutsk was revealed, it was reaching 10 (MPC for fishery waters). In Bol’shiye Koty settl., there were no cases of precipitations pollution above the accepted norms. At the station in Baikal Natural Reserve, a single (MPC for fishery waters). MAC increase was revealed. Income of oil hydrocarbons from the atmosphere onto lake water area was estimated as 200-250 tons/year. The results obtained are comparable with data of Lake Baikal State monitoring.
