Superfund Research Program
Sources and Pathways of Urban Heavy Metal Exposure Using Elemental and Isotopic Composition of Environmental Samples
Project Leader: H. James Simpson

- Project Summary
Project Summary (1995-2000)This project is focused on the identification of current and previously unrecognized urban sources of environmental lead using dated environmental samples. Samples include airborne particulates; New York Harbor, Hudson River and reservoir system sediment cores; soil, water and sewage sludge. Sources of lead are identified through the techniques of stable isotope analysis complemented by "finger printing" using trace element analysis. These data are essential for development of rational strategies of exposure prevention.
