The levels of 13 organochlorine pesticides (OCPs) were measured in breast milk from 87 Tunisian mothers throughout their lactation periods. Breast milk levels of OCP residues were determined using a validated methodology that included capillary column gas chromatography with electron-capture detection. All samples contained detectable residues of p,p'-DDE (2.421 mg/kg milk fat) and HCB (0.260 mg/kg milk fat). The other OCP residues were detected in the following order of frequency: Dieldrin 38%, beta-HCH 22.9% and gamma-HCH 6.8%. It was made an attempt to point out the relationship between some factors and the transfer of OCP residues into breast milk. In this study we found that concentrations of OCPs increased with mothers' age, these levels decreased with the number of children.
对87名突尼斯母亲哺乳期的母乳中13种有机氯农药（OCPs）的含量进行了测定。采用经过验证的方法测定母乳中OCPs残留量，该方法包括带电子捕获检测的毛细管柱气相色谱法。所有样本均含有可检测到的p,p'-滴滴伊残留（2.421毫克/千克乳脂）和六氯苯残留（0.260毫克/千克乳脂）。其他OCPs残留按以下频率顺序被检测到：狄氏剂38%、β-六氯环己烷22.9%和γ-六氯环己烷6.8%。试图指出一些因素与OCPs残留向母乳中转移之间的关系。在本研究中，我们发现OCPs的浓度随着母亲年龄的增长而增加，这些水平随着孩子数量的增加而降低。
