Popis: In the residential area under the impact of emissions from non-ferrous metallurgy and woodworking industry, the quality of atmospheric air was shown to fail to meet the requirements of hygienic standards for the content of suspended solids in air [≤ 4 MPC for maximal single dose (MPCmsd), ≤ 12.5 MPC for average daily dose (MPCadd), phenol (≤ 5.6 MPCmsd, ≤ 4.83 MPCadd), formaldehyde (≤ 1.56 MPCmsd, ≤ 6.58 MPCadd), fluoride gaseous compounds (≤ 3.75 MPCmsd, ≤ 12.4 MPCadd), etc. The quality of potable water in the centralized water supply system from surface water source corresponds to hygienic standards but, and in drinking water from the underground water source hygienic standards of iron content are exceeded (up to 1.1 MPC, 3.6% of samples). Also, in the study area, exceedances of permissible concentrations in lead soils are observed up to 2.09 MAC (7.84% of samples) and fluorine up to 4.68 MPC (87.04% of samples). The individual carcinogenic risk for the children of the study area is, on average, 1.18 ∙ 10-3, for the adult population, an average of 5.25 ∙ 10-3, and exceeds the acceptable level of carcinogenic risk by about 52.5 times. The individual non-carcinogenic risk for the short-term exposure to chemicals is by up to 9 times higher than the acceptable level. The individual non-carcinogenic risk for the chronic multimodal intake of the studied chemicals exceeds the permissible value of the total hazard index by to 33.4 times with respect to respiratory disorders. Priority factors that determine the level of risk to public health are chemicals present in emissions from enterprises producing primary aluminum (Benz(a)pyrene, fluorides, sulfur dioxide, suspended substances) and cellulose (phenol, methyl mercaptan).
