LANDFILLS OF MUNICIPAL SOLID WASTES AS SOURCES OF IMPACT ON THE ENVIRONMENT (ECOLOGY-GEOCHEMICAL ASPECT)

В. Е. Закруткин

Abstract

Impact of the municipal solid wastes (MSW) landfills on the environment is caused by issue of a filtrate and biogas and also atmospheric transfer of material of waste from a surface. As a result an underground water and surface water, soils, unsaturated zone deposits, atmospheric air are exposed to intensive pollution. The most active and aggressive agent of transformation of components of the environment near landfills of solid municipal waste is the filtrate which impact, first of all, on underground waters. The filtrate composition distinguished by a high mineralization and abnormal content of chlorides, sulfates, nitrates, nitrites, heavy metals, oil products and hydrocarbons. Zone of influence on groundwater reaches 400?500 m from border of the landfill of solid municipal waste. In the soils of territories, adjacent to landfills of municipal waste, high concentrations of bismuth, tin, lead, cadmium, antimony, copper and zinc are found. Influence of the MSW landfills on atmospheric air consists in emanation and further migration of the biogas which is consisting, generally from methane and carbon dioxide with including impurities of heavy hydrocarbons, hydrogen, hydrogen sulfide, nitrogen oxides and ammonia.
