The systematic identification and determination of many kinds of pesticides were attempted by a combination of column, thin-layer and gas chromatography. Twenty-one pesticides in the second division2)- e. g., α-, β-, γ-, _??_-BHC, trifluralin, CPA, nitrofen, endrin, dieldrin, dicofol, etc. were separated from 15 pesticides in the third division-e. g., dichlone, EPN, anilazine, chlorpropyrate, chlorpropham, folpet, barban etc., and pesticides in the third division were also separated from those in the fourth division-e. g., trietazine, prometryne, propazine, atrazine, BPMC, carbaryl etc. by column chromatography. Furthermore, these pesticides in the second and third divisions were separated from each other and determined by gas chromatography with ECD, FTD and FID, after division into 4 groups by TLC. Most of these pesticides were more than 90% recovered through the whole procedure.
