ABSTRACT- An ecological risk assessment was conducted for a 59-acre trap shooting range in Ohio where approximately 6,000,000 targets are thrown and 207 tons of shells deposited each year. This risk assessment followed a final Phase II Environmental Due Diligence Audit (EDDA) on the effects of lead shot and clay pigeon fragments in soils of the site. Soils were dry sieved to remove lead pellets and target fragments. Chemicals of potential concern in the soil included lead and arsenic from the shot and PAHs from the targets. The range is surrounded by a fence that discourages deer. The assessment endpoints for ecological risk were the survival of birds, represented by American robin, and mammals, represented by meadow vole, on the grassy trapshooting area and exposed fish and aquatic invertebrates in the stream that drains that area. Risks from in-place stream sediments were assessed using the PAH model, which predicts toxicity of mixtures of PAHs to amphipods. Ecological risks to wildlife populations and to stream invertebrates on the parcel were indicated from exposure to the soils. Previous assessments of trap shooting facilities have addressed the lead shot, and this study may be the first to address the contaminants in the soils of a trapshooting range.
