Estimation of Organochlorine Pesticides and Dioxin-Like PCBs in Surface Sediments from Baihua Lake
The concentration of eight organochlorine pesticides (OCPs) and twelve dioxin-like polychlorinated biphenyls (dl-PCBs) were estimated in nine surface sediment samples from Baihua Lake. Gas chromatography with mass spectrometry (GC-MS) was applied using selected ion monitoring (SIM) mode for the quantification of the OCPs and for the qualification of the dl-PCBs. The results showed that the concentrations of DDTs varied from 1.04 to 36.74 ng g-1 (dry weight) in these sampling locations, and that of HCHs was in the range from 0.57 to 8.90 ng g-1. In addition, PCB167 and PCB169 were detected in several sediment samples.
