Abstract
Abstract
In this study, an environmental site investigation was conducted of a typical lead (Pb)-related production plant. Based on a combination of manual and Geoprobe sampling, Pb concentrations in soils were measured using standard analytical methods to clarify the distribution of Pb concentrations in soils of the plant’s production workshops, open spaces within the plant, and in the adjacent farmland. The results show that the maximum depth of Pb pollution in the soil of the production workshop was 1.5 m. Pb pollution was found in the soil of the adjacent farmland within a range of 50 m from the plant and occurred at a maximum depth of 0.15 m. Probably as a result of the characteristics of Pb species, there was little horizontal movement of Pb observed in the sampled soils. Further, the solid ground surfaces in the plant (e.g., hardened concrete) effectively prevented the pollution of subsurface soil by Pb.
