영어 초록

An attempt was made to determine the residual distribution of organochlorine and organophosphorus pesticides in the various kinds of Korean tea which were purchased from the market. The organochlorine pesticides investigated in this study were BHC, DDT and dicofol and the organophosphorus pesticides were diazinon, EPN, fenitrothion and parathion. The pesticide residues were determined by GC-ECD and NPD. Only BHC was detected in all the samples and it's level were ranged from 0.00064 ppm to 0.05995 ppm and it's average was 0.00682 ppm and DDT, dicofol and organophosphorus pesticides were not detected in all samples. The organophophorus pesticides were detected(0.0035-0.0983 ppm) in raw materials but were not in the manufactured material and it is considered that the largely components of the pesticides is removed by drying and high temperature while the tea was manufactured. The recovery tests of the pesticides gave satisfactory results showing an average yield of 97.6% with organochlorine pesticides and 92.5% with organophosphorus pesticides and the detection limits level were 0.00008 ppm to 0.0010 ppm.
