A total of 74 soil samples were collected from three major types of soils,garden soil,paddy soil and natural soil in the Pearl River Delta,for quantitative analysis of residues of cischlordane (CC) and trans-chlordane (TC),and for enantiomeric ratios of those two chiral organochlorine pesticides.Results indicate that the concentrations of TC and CC were in the range of <0.01～13.70 and <0.01～15.70 ngg^-1,respectively,and appeared to be lognormally distributed.And of above 80 percent of the samples,concentrations were in the range of 0.1～1.0ng g^-1.The special high levels of chlordane in soils might be attributed to the use of the substance in the vicinity.Pesticide residues were not proportional to soil organic carbon content.
