The anthropogenic hydrogeochemical anomalies within the region of the Kola Peninsula are grounded, the development of the latter being associated with direct emissions and sinks of the mining and smelting enterprise as well as with the indirect leaching of the elements with acidic precipitation. The original data are given according to the level of Ni, Cu, Sr, Al, Zn, Co, Mn, Pb, Cd, Hg, As in the organs and tissues of fish; the consistent patterns of their accumulation are examined based on their content in the water. The author identifies the endemic fish pathology whose etiology is partially tied to the accumulation of metals and to the disorder of microelemental composition of the organism. The ecotoxicological assessment of the environmental effects of the emergence of anthropogenic provinces (copper-nickel, strontium and acidified) within the region is given.
Обосновываются техногенные гидрогеохимические аномалии в пределах Кольского региона, развитие которых связано как с прямыми выбросами и стоками горно-металлургического комплекса, так и с опосредованным выщелачиванием элементов кислотными осадками. Приводятся оригинальные данные по уровням содержания Ni, Сu, Sr, Al, Zn, Сo, Мn, Pb, Сd, Нg, As в органах и тканях рыб; рассматриваются закономерности их накопления в зависимости от содержания в воде. Выявлены эндемичные патологии рыб, этиология которых связана с накоплением металлов и нарушением микроэлементарного состава организма. Дана экотоксикологическая оценка экологических последствий образования техногенных провинций в пределах региона медно-никелевых, стронциевых и закисленных.
