Abstract

It is an anthropogenic factor that causes high levels of urban pollution around the world. This mainly leads to soil contamination with heavy metals. Heavy metals enter the soil in vehicles, industrial plants, thermal power plants, and military training grounds. The danger of contamination of soils with toxic substances is that the toxins that enter the soil are stored for many years and affect the processes of the soil, such as agrochemical, agrophysical, biological, microbiological properties, nutrients, and eventually enter our body through the food chain. With this in mind, when we studied the wastes of private machine-building enterprises from an ecological and hygienic point of view, the hazard classes of environmental pollution were studied. The waste was found to contain lead, tin, copper, iron oxides, polyethylene and petroleum products.
