This study assesses the degree of trace metal translocation from the coal matrix (lignite) into slag and ash for the following metals: Hg, Pb, Ni, and Cd. Stored in heaps in the soil and plants from the local residential environment, near the power plant. Analysis of trace metals in the multicomponent sample was carried out by AAS. Within the coal, ash, and slag samples, as well as in the vegetation and soil surrounding the power plant's sphere of impact, heavy metals were discovered. For filter ash, RE Meiji ≈1 (Ni and Cd) and RE Meiji < 1 (Pb and Hg) indicate the enhanced metal level in the residues. Both Pb and Ni levels in the soil are higher than average, and Pb levels are also beyond the warning threshold for sensitive soils near garbage disposal (70.20 mg.Kg-1). The translocation factor (TF) indicates that the presence of heavy metals in soil and plants pushes Cd and Hg over the bioaccumulation reference value (Khan) of 0.5 and individual carcinogenic risk for Pb Ni Cd estimated at levels of: 10-7; 10-6; 10-5 relative to the WHO reference limit of 10-6: it estimates a potential food safety risk.
