title: [Distribution characteristics and risk assessment of organochlorine pesticides in soil from Jiufeng Mountain Range in Fujian, China].
abstract: Totally 81 surface soil samples were collected from Jiufeng Mountain Range, and 8 compounds of organochlorine pesticides (OCPs) were determined by a Ni electron capture detector (GC-ECD) to investigate the distribution, composition, source and potential health risks of these compounds in the study region. The detection ratio of HCHs and DDTs' isomers ranged from 77.78% to 100.00%. Concentrations of HCHs and DDTs in surface soils ranged from 0.97 ng x g(-1) to 247.40 ng x g(-1) (mean 10.17 ng x g(-1)) and 0.01 ng x g(-1) to 384.75 ng x g(-1) (mean 18.91 ng x g(-1)), respectively. Compared with other regions, the pollution of OCPs in Jiufeng Mountain Range stayed at a low level. The residue level in different types of lands was in the order as: paddy field > vegetable land > tea land > woodland. Source analysis indicated that Lindane and dicofol might be used recently in this area. The incremental lifetime, cancer risks (ILCRs) of different age groups (children, youths, and adults) were all within the acceptable risk range of 10(-6) to 10(-4) recommended by USEPA for carcinogenic chemicals. The residue level of OCPs in soil may not cause cancer risk for local residents basically.
