Chemistry for Sustainable Development 15 (2007) 359-365 Modern Levels of the Accumulation of Polychlorinated Diphenyls in the Objects of the Baikal Natural Territory
Abstract Concentrations of polychlorinated diphenyls (PCD) were measured in snow cover (10-520 ng/m 2 ), in the soil (0.3-45 ng/g of dry mass) of Pribaikalia and the southern lakeside, in bottom sediments of Lake Baikal and its tributaries (0.3-3.9 ng/g of dry mass), in Baikalian omul (Coregonus aut...
