Abstract

Shooting ranges represent about 10% of polluted sites in Switzerland. This pollution, mainly consisting of lead (Pb) and antimony (Sb), can spread into the local groundwater, wildlife, and plants. In this study, shooting range stop butt soils (elevated soil mount behind the target) of 3 sites (Versoix, Cartigny and Nyon, Western Switzerland) were investigated for metal contamination and culturable lead-resistant bacteria in contaminated soils. The ICP-MS analysis of surface stop butt soils (0-5 cm) indicated high metal concentrations especially for Pb and Sb; e.g. the Pb concentration ranging from [61,135 to 395,651], [23,821 to 201,268] and [120 to 27,517] mg kg-1 in the soil from the sites of Versoix, Cartigny and Nyon, respectively. Molecular analysis of 16S rRNA gene demonstrates the presence of bacteria from diverse classes: Flavobacteriia, α-Proteobacteria, γ-Proteobacteria, Actinobacteria and Bacilli that exhibited high Pb MIC value from 1,036 to 2,694 mg kg-1. The isolated strains could be the subject of further studies to evaluate their role in bioremediation of lead contaminated soil.
