The concentration profile of copper and lead in the soil and foliage of an urban forest in Cincinnati, Ohio, was examined. The relationship of the profile to tree type, location, and vegetation, soil and site attributes was also studied. Results showed an elevated metal level near the forest edge and highway. Sites located in the forest interior had a much lower metal burden. Pine needles retained more metals, suggesting that they may be a good repository for airborne particles. Significant relationships between the foliar copper loadings with site aspect, elevation and slope angle were also identified.
