Heavy Metals in Soils Affected by Coal Enterprises and Their Impact on Human Health
Concentrations of heavy metals in Southern Kuzbass urban soils affected by coal mining industry and sity boilers were studied. The risks of toxic effects of elements found in soils as a result of geochemical sampling (200 samples) were identified. The hazard ratio during the intake of elements - toxins into the human body orally and via inhalation was calculated. Analysis of uncertainty in the estimation of the average daily doses was carried out. The obtained risk parameters fall into the category of permissible or acceptable. The primary contribution to the total hazard ratio is made by the manganese, cobalt, copper, and arsenic. These elements show special features of the soil in the affected area of coal mining, urban boilers everywhere and the activity of repair — metallurgical and foundry businesses locally. No pronounced differentiation of the city areas according to the value of the hazard ratio was discovered.
