Abstract

Dieldrin, a potent residual insecticide and common contaminant of the environment, is metabolized in liver and kidney of broiler to photodieldrin, a photoisomer of dieldrin. This metabolite has by gas-liquid chromatography (g.l.c.) analysis a retention time different to the aldrin. The analysis by thin-layer chromatography (t.l.c.) of metabolite shows an Rf of 0.37. The i.r. (infra-red) spectrum shows the band corresponding to the epoxide ring (800-1300 cm-1) and does not show the characteristics bands of C = O (1800 cm-1) and ClC = CCl (1600 cm-1).

摘要

狄氏剂是一种强效残留杀虫剂，也是常见的环境污染物，在肉鸡的肝脏和肾脏中会代谢为光狄氏剂，即狄氏剂的一种光异构体。通过气液色谱法（g.l.c.）分析，这种代谢物的保留时间与艾氏剂不同。代谢物的薄层色谱法（t.l.c.）分析显示其比移值为0.37。红外光谱显示了与环氧环相对应的波段（800 - 1300厘米⁻¹），但未显示出C = O（1800厘米⁻¹）和ClC = CCl（1600厘米⁻¹）的特征波段。
