摘要: ABSTRACT The city of East St. Louis, IL, has a history abundant industrial activities including smelters ferrous and non-ferrous metals, coal-fired power plant, companies that produce organic inorganic chemicals, petroleum refineries. A protocol for soil analysis was developed to sufficient information on the extent heavy metal contamination in Louis soils. Soil cores representing every borough were analyzed metals—As, Cd, Cu, Cr, Hg, Ni, Pb, Sb, Sn, Zn. topsoil contained concentrations as high 12.5 ppm 14,400 quantities 1860 40 1130 10,360 Concentrations Cd well correlated with Zn concentrations, suggesting similar primary source. In sandy loam from vacated rail depot near bank Mississippi River, metals evenly distributed down 38-cm depth. clay soils within half-mile downwind sme...
