    We evaluated the effect of a shooting range on Pb contamination of adjacent agricultural soils and the associated environmental risks. Pb was concentrated in arable layer of the contamined site (573 to 694 mg kg−1), representing 12-fold Pb content as compared with subsoil and control site. Isotopic analyses (206Pb/207Pb) proved that Pb originated predominantly from the currently used pellets. The 0.05 M EDTA extraction showed that up to 62% of total Pb from the contaminated site is potentially mobilizable. Increased Pb concentrations (in comparison to control site) were found in both studied plant species: cultivated spring barley and the moss Hypnum cupressiforme. This study showed that shooting ranges can present an important source of Pb contamination of agricultural soils located in their close vicinity.
