IMPACT OF NATURAL FACTORS ON MERCURY IN LAKES OF THE NORTH OF WESTERN SIBERIA
The relevance of the study is caused by the fact that mercury is involved in the global planetary biogeochemical cycle and is included in the food chain with the accumulation in organisms of predatory species of animals and in the indigenous population. With respect to Western Siberia, studies are f...

The relevance of the study is caused by the fact that mercury is involved in the global planetary biogeochemical cycle and is included in the food chain with the accumulation in organisms of predatory species of animals and in the indigenous population. With respect to Western Siberia, studies are fragmentary, and generalizations are made on small samples, which makes background studies of mercury content in the bottom sediments of lakes relevant in a representative sample. The aim of the study is to analyze and generalize the background space-time observations of the gross mercury content in the bottom sediments, as well as dissolved, depending on natural factors in the middle taiga within the Khanty-Mansiysk Autonomous Okrug. The object of study is the background concentration of dissolved Hg and mercury in the bottom sediments of lakes. 95 lakes, 322 samples of bottom sediments taken at different times were studied. Methods: atomic absorption spectrometry («cold steam» method) determination of mercury in accredited laboratories in accordance with the guidelines.
