군 소화기 사격장 부지의 납 토양오염 분포 특성 = The Characteristics of Soil Lead Contamination in Military Rifle Shooting Ranges

다국어 초록 (Multilingual Abstract)

This study investigated the soil contamination characteristics of military rifle shooting ranges. 4 shooting ranges, includingzeroing range, were chosen for the investigation and were classified as 3 areas (berm, target, and range floor) in eachshooting range for soil sampling. The leaching concentrations of lead in the berms by SPLP (synthetic precipitationleaching procedure), 0.13 mg/L ~ 2.14 mg/L, were significantly higher than those of copper and zinc, less than 0.2 mg/L.
This indicates that lead is a major contaminant in shooting ranges. Concentrations of lead by aqua regia were higher in theberm, followed by the target area and lastly the range floor due to the influence of bullets. As target distances from a firingpoint increased, the concentrations also increased because shooting uphill is general due to the topography of the ranges.
The concentration relationship between surface and subsurface soils was identified only in the range floors, where thereare fewer bullets. Surface soil concentrations were higher than subsurface concentrations in the range floors due to theeffects of contaminants leaching and soil loss from the berms and target areas. Therefore, the reduction of contaminantmobility and soil particulate loss has to be preferentially focused on in terms of the sustainable management of militaryshooting ranges.
