    Abstract
  • In order to study the OCPs in water body of the Laolongdong underground river basin, concentration of OCPs residues in the water sample are measured by gas chromatography equipped with micro-63 Ni electron capture detector. The results show that the α-HCH is the main ingredients of HCHs in water body of the Laolongdong underground river basin. The HCHs mainly comes from the atmospheric transmission. The essential component of DDTs is different with each other among the sampling sites. The historical usage of technical DDTs may cause DDTs pollution, and DDT was dechlorinated under aerobic conditions DDTs. Comparing with other rivers at home and abroad, the OCPs content in the water body of the Laolongdong underground river is in higher level.
