Abstract

According to the data obtained during fulfillment of the Federal target program “Protection of lake Baikal and socio-economic development of the Baikal natural territory for 2012-2020”, a map of petroleum products waste distribution in the snow cover, ice and ice water in the waters of lake Baikal and the surrounding areas was compiled. Samples from the Southern, Central and Northern parts of the lake were selected for the analysis. It is established that in the process of distancing from settlements with the big density of the population and large industrial objects the concentration of oil products waste in tests decrease. The highest concentration of petroleum products waste was observed in the samples of snow taken from the water area of the lake near the village of Bolshoye Goloustnoye and at the source of the Angara, in the area of Listvyanka, the most popular tourist and recreational settlements near lake Baikal, as well as near the cities of Nizhneselengisnky industrial hub – Nizhneangarsk and Severobaikalsk.
