This standard specifies the method for the determination of BHC and DDT residues in food. This standard applies to the determination of HCH and DDT residues in food. Gas chromatography detection limit: α-666, β-666, γ-666, δ-666 are 0.2, 0.8, 0.3, 0.4 μg/kg in sequence. p,p'-DDE, o,p'-DDT, P,P'-DDD, P,P'-DDT were 0.5, 2.7, 1.6, 4.0 μg/kg in sequence. The minimum detection amount of TLC is 0.02μg, and the suitable range is 0.02~0.20μg.
