Abstract

Childhood ingestion of Pb contaminated soil can result in cognitive deficits. The problem posed by Pb in soil is that it is relatively abundant in older urban yard soils, and is an exposure threat to under-served communities. To affect risk reduction, the preferred intervention technique is “excavation and removal”. However, this option is hardly a “costeffect” methodology that can be used widely. Here, we examine the use of low cost soil amendments that alter the form of the Pb in soil and render it less toxic. Our goal has been to add phosphate products to high Pb soils to convert the Pb to a less bioaccessible form (the Pb-mineral pyromorphite).
