The methods arc described for determinations of Al, Fe, Ca, Mg, Ba, Cr, Mn, Ni, Cu, Zn, Pb, Cd, V and Sr in botanical, coal fly ash and soil samples by flame atomic absorption spectrometry (FAAS), and inductively coupled plasma atomic emission spectrometry (!CP-AES). Special attention has been paid to sample preparation, an important stage at which a sample is explored to contaminants. Results of the analysis of all samples arc discussed.

The aim of the study was to estimate the content of trace elements: zinc, cadmium, lead, molybdenum and nickel in products and wastes of coal treatment from Upper-Silesian Basin. Two analytical methods were applied: atomic absorption spectrometry (FAAS, ETAAS) and anodic (ASY) and adsorptive stripping voltammetry (AdSY). ASY is used to determine zinc, cadmium and lead; AdSY molybdenum and nickel, and FAAS and ETAAS to determine all elements. In the case of Zn, Ni, Mo, Pb and Cd determined by FAAS (ETAAS) the concentrations were practically the same as those obtained by ASY or AdSY.
