Modeling the air-soil exchange, secondary emissions and residues in soil of polychlorinated biphenyls in China

Abstract The present study investigated the environmental distribution and fate of low molecular weight (LMW) polychlorinated biphenyls (PCBs) in China using the ChnGIPERM (Chinese Gridded Industrial Pollutants Emission and Residue Model), in which the air-soil exchange, spatial-temporal variations...
