Miljøkartlegging av åtte skytebaner - vurdering av potensialet for mobilisering av tungmetaller

Abstract

It has been carried out an environmental assessment study of eight shooting ranges for small arms. The main purpose of the study was to evaluate the potential for mobilization of soluble heavy metal species from contaminated areas into local recipients. Conclusions Measurements performed in this study indicate that two of the shooting ranges have high levels of lead, copper and antimony in runoff water. The heavy metal concentrations for lead and antimony are above the Norwegian quality criteria in drinking water. Both ranges are situated in areas with peat soils and much of the natural vegetation is damaged by bullets over several years. This cause surface runoff and heavy metal contamination of recipients in contact with the ranges. At ranges without peat soils, there are less problems with high heavy metal concentrations in runoff water.
