Characterization of ambient levels of metals and polycyclic aromatic hydrocarbons for surficial soil in the urban piedmont region of new jersey

摘要

This investigation implemented a statistically based sampling program to determine the ambient levels of metals and carcinogenic polycyclic aromatic hydrocarbons in municipalities that meet urban center population criteria within the Piedmont Region of New Jersey. New Jersey Department of Environmental Protection (NJDEP)'s geographic inforamtion system (GIS) and on-line aerial photography were used in the sampling sites selection process. For surveying of sampling locations, Global Positioning System (GPS) technology was used. For each location, 1 sample was collected at 0-15.2 cm and analyzed for 3 target analyte list metals, 6 carcinogenic polycyclic aromatic hydrocarbons, total organic carbon, pH, loss on ignition, and particle size. Detected concentrations would represent naturally occurring levels plus those resulting from diffuse anthropogenic pollution (DAP). Aresnic, cadmium, beryllium, and lead were detected in 13percent of soil samples at concentrations above state-proposed cleanup criteria. Carcinogenic polycyclic aromatic hydrocarbons were also detected in 18percent of the samples at concentrations above state propsoed cleanup criteria.
