Spatial distribution of HCH and DDT in soil from the Wuyi Mountains southern, Fujian, Southeast China
In order to study the levels and spatial distribution of organochlorine pesticides in soil samples from the Wuyi Mountains southern. The 30 soil samples were collected from the study area. The concentrations of OCPs in the samples were determined by GC-ECD with the internal standard method. The results showed that HCHs and DDTs were found widely in all samples and the concentrations of HCHs, DDTs in soils of the Wuyi Mountains were in the ranges of 1.14 30.62 ng g-1 (with a mean 5.04 ng g-1), 0.96 9.62 ng g-1 (with a mean 3.99 ng g-1), respectively. Compared to the reference data of Antarctic and Tebat area, the status of this area can be called "low pollution". Through source analysis, β-HCH and o,p-DDT was the major source of HCHs, DDTs, respectively. The results indicated that HCHs in this area were historical application. But, new DDTs (dicofol) could be used recently in this area.
