Abstract

The effects of chromic sulphate, which is commonly used in the tanning of leather, on the common carp, Cyprinus carpio and the bighead, Aristichthys nobilis, were studied. C. carpio was found to be more susceptible than A. nobilis to chromic sulphate at the lowest concentration tested (100 mg/l) whereas results obtained at other concentration were similar for both species. Damage to the gills, liver and intestine was observed by histopathological examination. A wide range of chemicals is used in the different stages of treating leather and a possible treatment of the effluent from the tanneries is suggested.

摘要

研究了常用于皮革鞣制的硫酸铬对鲤鱼（Cyprinus carpio）和鳙鱼（Aristichthys nobilis）的影响。在测试的最低浓度（100毫克/升）下，发现鲤鱼比鳙鱼对硫酸铬更敏感，而在其他浓度下两种鱼的结果相似。通过组织病理学检查观察到鳃、肝脏和肠道的损伤。皮革处理的不同阶段使用了多种化学物质，并提出了一种可能的制革厂废水处理方法。
