The paper evaluates the presence and content of traces of heavy metals Hg, Pb, Ni, Cd (total forms) from coal and solid combustion products, the degree of transfer and accessibility in the area of influence of a lignite power plant. The content of toxic heavy metals in residues are characterized by RE Meiji [ 1 (Pb and Hg) and REMeij �1 (Ni and Cd) for the filter ash. Pb and Ni content in the soil exceeds normal values, and Pb exceeds and alert value for sensitive soils around the residue deposit (70.20 mg.Kg-1). The degree of accessibility of the metals in plants (TF), reported at the Khan reference value (0.5), indicates a significant bioaccumulation level for the metals: Cd (1.9) and Hg (0.6) inside the deposit; Cd (0.39) at the base of the deposit, Hg (0.8) in the area of the thermal power plant. The trace levels of heavy metals analyzed by GFAAS and CVAAS (Hg), indicates a moderate risk potential for food safety and quality of life in the studied area.

A simplified method for the determination of dissolved organic carbon is based upon the ampoule–persulfate wet digestion procedure. The modification proposed involves use of a continuous stream of sparging gas (technical grade oxygen) during the ampoule sealing process to minimize entry of combustion products from the sealing flame. The method provides reliable results with a minimum of training and equipment compared with other methods of sealing ampoules. Further, the proposed method is inexpensive, relatively simple, and compares favorably with costly, automated analysis of dissolved organic carbon.
