摘要

The concentrations of organochlorine pesticides(OCPs) in the Laolongdong underground river basin in northern China were quantitatively analyzed using the gas chromatography-mass spectrometer(GC-MS).This study was to investigate the composition,distribution and source of OCPs in the waters.The concentrations of ∑OCPs ranged from 14.45 ng· L-1 to 307.92 ng· L-1 and the mean value is 79.42 ng· L-1.β-HCH and p,p ’-DDT were the most abundant components in ∑HCHs and ∑DDTs,respectively.There are some differences among the temporal and spatial distributions of ∑OCPs in underground river basin,and the distributions of ∑HCHs and ∑DDTs were same with ∑OCPs.The sources of OCPs analysis indicated that HCHs mainly came from the input of lindane and DDTs was from the mixture input of newly technical DDTs and dicofol.
