Изучение поступления тяжелых металлов в компоненты окружающей природной среды, на примере Хинганского месторождения оловянных руд Еврейской АО

Abstract

The author studies the heavy metal outflow from the territory of Khingansk tin deposit developed in the recent past. The results obtained indicate the significant pollution of soils and waters of the river Levy Khingan and its feeders with the heavy metal salts. A set of pollutants in concentration decrease in the media analyzed is introduced in the following way: in water Ni>Fe>Mn>Cu; in water extracts of soils and cleaning rejects Fe>Mn>Zn>Pb>Ni>Cu>Co>Sn>Cd; in the extracts with ammonium-acetate buffer solution Zn>Mn>Fe>Pb>Cu>Cd>Co>Ni. It was determined that the highest increase of heavy metal salt concentration in water is typical for nickel. It is to 8,6 MPC; for iron it is 5,5 and for manganese it is to 4,7; in the soil for zinc it is over 40, for lead it is over 15 and for manganese it is over 10 MPC.

Исследуется вынос тяжелых металлов с территории разрабатываемого в недавнем прошлом Хинганского месторождения олова. Полученные результаты указывают на выраженное загрязнение почв и вод р. Левый Хинган и его притоков солями тяжелыми металлами. Ряд загрязнителей по уменьшению концентрации в анализируемых средах, представлен следующим образом: в воде Ni>Fe>Mn>Cu; в водных вытяжках почв и отходов обогащения Fe>Mn>Zn>Pb>Ni>Cu>Co>Sn>Cd; в вытяжках аммонийно-ацетатным буферным раствором Zn>Mn>Fe>Pb>Cu>Cd>Co>Ni. Установлено, что наибольшие превышения концентраций солей тяжелых металлов в воде характерны для никеля до 8,6 ПДК, железа 5,5, марганца до 4,7; в почве для цинка свыше 40, свинца свыше 15, марганца свыше 10 ПДК.
