The effects of chloridazon exposure at concentrations of 2.7 μg/L (maximal real environmental concentration in the Czech Republic), 27 μg/L, 135 μg/L and 270 μg/L on early life stages of marbled crayfish (Procambarus virginalis) were evaluated. Significantly higher glutathione S-transferase activity and reduced glutathione level was observed at all tested concentrations of chloridazon compared with the control. Chloridazon in concentrations 27, 135 and 270 μg/L caused delay ontogenetic development and slower growth. Histopathological changes in hepathopancreas were found in two highest tested concentrations (135 μg/L and 270 μg/L). Crayfish behaviour was not altered in control vs. exposed animals, while the activity parameters tend to decline with increasing chloridazon concentrations.
研究了浓度为 2.7μg/L（捷克共和国最大实际环境浓度）、27μg/L、135μg/L 和 270μg/L 的氯哒唑对大理石小龙虾（Procambarus virginalis）早期生命阶段的影响。与对照组相比，所有测试浓度的氯哒唑均显著增加了谷胱甘肽 S-转移酶活性和还原型谷胱甘肽水平。氯哒唑在 27、135 和 270μg/L 浓度下导致发育延迟和生长缓慢。在两个最高测试浓度（135μg/L 和 270μg/L）下发现了肝胰腺的组织病理学变化。与暴露组相比，对照组的小龙虾行为没有改变，而随着氯哒唑浓度的增加，其活动参数有下降的趋势。
