目的 测定金线莲中六六六（BHC）和滴滴涕的残留情况。方法 采用气相色谱法（GC）对金线莲中BHC（α-BHC、β-BHC、γ-BHC、δ-BHC）、滴滴涕（PP'-DDE、PP'-DDD、OP'-DDT、PP'-DDT）8种有机氯类农药残留的限量检测。结果 BHC、滴滴涕标准工作曲线的线性良好，相关系数0.998 8~0.999 7，平均回收率95.4%~98.9%，RSD为1.00%~2.98%。检出限为0.005 3~0.021 μg/L。测定结果显示：β-BHC为0.000 9 mg/kg（其中α-BHC、γ-BHC、δ-BHC、PP'-DDE、OP'-DDT、PP'-DDD、PP'-DDT未检出）。结论 该方法具有较高的灵敏度和线性范围，测定结果准确可靠，科学可行，可用于金线莲中BHC和滴滴涕农药残留的质量监控。

Objective Determination of 666 (BHC) and DDT residues in Anoectochili Roxburghii Gemma Terminalis. Methods Using gas chromatography (GC) for limited detecting the eight kinds of organochlorine pesticide residues, such as BHC (α-BHC, β-BHC, γ-BHC, and δ-BHC) and DDT (PP'-DDE, PP'-DDD, OP'-DDT, and PP'-DDT) in Anoectochili Roxburghii Gemma Terminalis. Results Linear BHC and DDT standard curve were good, the correlation coefficient was 0.9988-0.9997, the average recovery rates were 95.4%-98.9%, 1%-2.98% RSD. The detection limitation was 0.0053-0.021 g/L. Result of Chinese herbal medici:β-BHC for G 0.0009mg/kg(Among them, α-BHC, γ-BHC, δ-BHC, PP'-DDE, OP'-DDT, PP'-DDD, PP'-DDT not detected) Conclusion The method is accurate, reliable, scientific, and feasible, and has higher sensitivity and linear range, which can be used for quality control of pesticide residues in water.
