The impact of lead-containing slag wastes on the life safety

Abstract

[EN] The article presents the analysis and results of the study of technogenic slag waste of leadzinc production. Lead-containing slag waste contains a large number of toxic compounds of heavy metals, such as lead, zinc, osmium, cadmium, which are dangerous sources of environmental pollution. Due to the open storage of slags, there is an excess of the maximum permissible concentrations (MPC) of lead: near the plant, the concentration of lead is more than 3000 mg/kg in the soil, with a MPC of 3.2 mg/kg. Lead and zinc compounds are dangerous for humans due to their significant toxicity and the ability to accumulate in the body. The article presents the analysis and results of studies of lead-containing slags on toxic compounds and their impact on human health. The results of the conducted studies have shown that poisoning with leadcontaining toxic slags leads to such consequences as damage to the brain, nervous system, cardiovascular system, digestive system, kidneys and blood in children and adults. According to the research results, lead gets into products from dishes (covered with lead glaze) and showers. In the blood ¿ basophilic granularity of red blood cells, reticulocytosis. The increase in the lead content in the urine is more than 0.04 mg /l.
