Surface Soil Metal And Metalloid Contamination Within The Urban Environment Of Atlanta, Georgia, Lanier Henson

Geosciences Theses

Previous research from urban cities around the world have found elevated soil lead concentrations in many of the cities because of anthropogenic deposition of lead from industrial, transportation, and residential applications. Children, impoverished populations, and pregnant women all experience increased adverse health risks when exposed to land with elevated soil lead concentration. The project tested the following hypotheses concerning soil lead within the Atlanta urban environment; soil is enriched from transportation sources and deteriorating lead paint, soil lead is not sourced from the weathering of the bedrock or soil, and enrichment is heterogeneous. The hypotheses were tested through the geochemical …
