Abstract

Over the past few decades, intensive industrialization and intensive agricultural activity have led to the accumulation of various pollutants in the environment, especially heavy metals. The negative effects of environmental pollution by heavy metals pose a real threat to the biosphere.

Heavy metals are among the widespread pollutants, the monitoring of which is mandatory in soils and soils. Heavy metal pollution is one of the causes of soil degradation. Annual surveys are the main source of information about pollution.

The article presents the results of a study of residual amounts of heavy metals (Fe, Cu, Zn, Co, Pb) in soil samples collected on the territory of the Kazakh Research Institute of Agriculture and Horticulture landfill in the Almaty region. In all the studied sites, the residual content of heavy metals in the soil samples was at an acceptable level. However, due to the peculiarities of the physical and geographical area, the proximity of the landfill site to the highway, etc., it was noted that metals such as zinc, lead, cobalt exceeded the MPC value by 2.1-6,2 times. Soil contamination with heavy metals causes accumulation of metals by plants and degradation of plant communities, which leads to the transfer of toxic substances through food chains to humans. In this regard, the purpose of this work is an urgent issue of our research topic on the content of heavy metals (Fe, Cu, Zn, Co, Pb) in light-dark brown soils of Southeastern Kazakhstan.
