Forty to fifty years after lead was removed from gasoline and paint in the USA, we review the environmental history and human exposure of legacy lead in soil. We describe two studies of legacy lead in Greensboro and Durham soils that will be the first maps of soil lead in cities in NC.
Dr. Daniel Richter's research and teaching links soils with ecosystems and the wider environment, most recently Earth scientists' Critical Zone. He focuses on how humanity is transforming Earth's soils from natural to human-natural systems, specifically how land-uses alter soil processes and properties on time scales of decades, centuries, and millennia.
Dr. Emmanuel Obeng-Gyasi completed his doctorate in Environmental Health and Epidemiology at Indiana University, Bloomington. He uses biostatistics, epidemiology, molecular biology, and analytical chemistry techniques to investigate the effects of environmental toxicants on the environment and populations.
