Abstract: Ten kinds of organochlorine pesticide residues including residues of heptachlor,aldrin BHC and DDT in soil were determined by gas chromatography using internal standard method.RSD′s (n=7) of these pesticides found by the precision test were in the range from 4.2% to 22.0%.Recoveries found by standard addition method were in the range of 70.3%-119.0%.The feasibility of this method was proved by the analysis of some soil samples.
