"Trace metal contamination studies were conducted near the Buick Resource Recycling Division. This study used sequential extraction, total digestion, X-Ray Diffraction (XRD), and Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS) to study trace metals in two soil cores. Sequential extraction analysis of the soil cores revealed that lead was associated with either iron or manganese oxides. Zinc and copper were bound to soil components, extracted mainly from organics, sulfides, and clays. Total digestion results compared favorably to the sum of the sequential extraction results for lead, thus validating the sequential extraction methodology. The highest concentration observed for lead was 4,743 parts …
