Scanning electron microscope studies were performed on the peripheral muscle network (myoepithelium) of the hepatopancreatic ceca of Gammarus pulex (L.) exposed to lindane, copper, or 3, 4-dichloroaniline (3,4-DCA) for a 24-hr period. The structural integrity of the myoepithelium of gammarids from control and test treatments was assessed using semiquantitative techniques. The lowest observed effect concentrations for structural changes were determined as 29.8 microg liter-1 lindane, 55 microg liter-1 copper, and 8.7 mg liter-1 3,4-DCA. The sensitivity of the bioassay and the significance of the morphological changes observed in the hepatopancreatic ceca of G. pulex are discussed.
对暴露于林丹、铜或3,4-二氯苯胺（3,4-DCA）24小时的蚤状溞（Gammarus pulex，L.）肝胰腺盲囊的外周肌肉网络（肌上皮）进行了扫描电子显微镜研究。使用半定量技术评估了对照和试验处理的蚤状溞肌上皮的结构完整性。确定结构变化的最低观察效应浓度为29.8微克/升林丹、55微克/升铜和8.7毫克/升3,4-DCA。讨论了生物测定的敏感性以及在蚤状溞肝胰腺盲囊中观察到的形态变化的意义。
