Description	The content, forms of bonding and isotopic compositions of lead (Pb) were studied on selected coal samples from the Czech Republic. Lead in most samples of bituminous and brown coal is mobilized by 3 M HCl. Thus, Pb could be bonded in carbonates and oxides and also to sulphides present in the coal. Bituminous coal contains an average of 33 mg/kg Pb, while brown coal contains an average of 8.9 mg/kg Pb. The 206Pb/207Pb ratio varies in the range 1.167?1.234 for bituminous and 1.172?1.24 for brown coal. No inverse proportionality of the Pb content and the 206Pb/207Pb ratio was observed in the studied samples and, thus, the Pb content in most samples is a result of the combination of lithogenic and ore Pb. It was not possible to demonstrate any statistical dependence between the operational defined speciation of Pb, the mineralogical composition and the Pb isotopic composition.
