建立了蛋和蛋制品中六六六、滴滴涕残留量的气相色谱检测方法。样品经正己烷提取、浓硫酸净化，气相色谱分离后，电子捕获检测器检测，外标法定量。在5 µg/kg~20 µg/kg添加水平，回收率在75.4%~90.3%之间，变异系数在2.5%~9.1%之间。以S/N=3计算，方法最低检出限为5.0 μg/kg。结果表明，该法简便、灵敏、准确，适用于鸡蛋中的六六六、滴滴涕残留量的分析。

A method was developed for the determination of BHC and DDT residues in eggs and egg products by gas chromatography (GC). Samples were extracted by hexane, purified by concentrated sulfate acid, and then analyzed by GC-ECD. Within the concentration range of 5 µg/kg~20 µg/kg, the recovery rates and variation coefficients were 75.4%~90.3%, and 2.5%~9.1%, respectively. The detection limit was 5.0 μg/kg (S/N=3). This method was simple, sensitive and precise, suitable for the qualitative and quantitative analysis of BHC and DDT residues in eggs and egg products.
