摘要

Previous investigations at American and Canadian shooting ranges have shown elevated levels of explosive residues in soil, water and ground water. The distribution of explosive residues has been shown to be particularly heterogeneous, thus making the sample collection procedure vitally important. In the present study, soil samples covering three training activities; anti-tank area, hand grenade range and a crater area at Alvdalen shooting range were collected following a systematic random design. A laboratory processing method was developed for multi-increment composite samples, 0.5-1.5 kg in size, before the samples were analyzed by liquid and gas chromatography. Trace metal analysis was only performed in the anti-tank area. In general, low levels of explosive residues were found at all the investigated sites.
