PBDEs Pollution of Soil in a E-waste Disposal Site and Its Surrounding Area

Concentrations of 8 kinds of PBDE congeners (BDE-28、BDE-47、BDE-99、BDE-100、BDE-153、BDE-154、BDE-183、BDE-209) in soils of a typical e-waste disposal site and its surrounding area in Taizhou, Zhejiang were determined with the accelerated solvent extraction (ASE) – gel permeation chromatography technology (GPC) – GC – MS method, to study concentration level, composition characteristics and vertical distribution of the pollutants in the area. Results show that BDE-209 was the major pollutant, accounting for 90% of the content of the total 8 PBDEs in the soil. The total concentration of the pollutants in the soil was higher in the site per se that in its surrounding area, being 0.625 and 0.209 mg•kg^-1, respectively. PBDE concentration decreased with the distance from the center of the disposal site.
