Section: Monitoring of natural and anthropogenically disturbed areas
In the winter-spring, in the summer and fall of 2016-2018 complex physiographic researches in east Priolkhonye with sampling of snow, soils and a surface water are conducted. Local pollution of snow and atmospheric air near settlements and camp sites of the coast of the Lake Baikal is revealed. Content of ammonium, phosphates and oil products in snow exceed maximum allowable concentration. Pollution of coastal waters of Small Sea Strait and the Sarma River in a recreational zone is established. Ecological, chemical and physical soil properties of meadow and steppe landscapes of Olkhon district in the territory of the east coast of the Lake Baikal which is most visited by tourists are studied. The explored soils have mainly low-power strong and middle stony profile, light particle size distribution, high content of a humus, mainly neutral and weak alkaline reaction. As a result of the conducted researches it is revealed that soils near tourist tracks are polluted by heavy metals. The ecological condition of soils at the present stage can be characterized as average degree of a disturbance as a result of recreational activity. Geochemical barriers are - organic and alkaline. However owing to light particle size distribution of soils there can be a pollution of waters of a coastal zone of the lake.
