Abstract

The levels of DDT residues were studied in 145 breast milk samples 25 days postpartum from women living in various rural populations where DDT has been used in farming activities and to interrupt malaria transmission. All participants showed quantifiable milk levels of DDT residues in the range from 5.1 to 68.3 micrograms/l and their levels significantly increased (P < 0.05) with maternal age. The determination of DDT residues (as DDE) in human milk was performed after a saponification process by gas chromatography with electron-capture detection. Confirmatory analysis was achieved using high-performance liquid chromatography with a diode array detection.

摘要

对居住在农村不同地区的妇女产后25天的145份母乳样本中的滴滴涕残留水平进行了研究，这些地区在农业活动中使用滴滴涕来阻断疟疾传播。所有参与者母乳中的滴滴涕残留水平均可量化，范围为5.1至68.3微克/升，且其水平随母亲年龄显著增加（P<0.05）。通过气相色谱 - 电子捕获检测法在皂化过程后测定母乳中的滴滴涕残留（以滴滴伊计）。使用带二极管阵列检测的高效液相色谱法进行确证分析。
