Activated sludge, chicken manure and pig manure were tested for their toxic effects as supplementary feeds for the common carp, Cyprinus carpio. The acute toxicity test showed that animal manures were more toxic than activated sludge (e.g., 96-h LC50 values for pig manure and chicken manure were 0.55% and 0.29%, respectively, while no effective value was revealed for activated sludge). This may be due to the inadequate processing of the manures which resulted in the release of harmful substances during decomposition. In general, body weights of all the fish fed the wastes decreased during the culture period. High heavy metal concentrations (Pb, Cu, Zn and Mn) were found accumulated in the flesh of the fish fed the wastes. It is suggested that waste materials should be pretreated and detoxified before using them as animal feeds.
对活性污泥、鸡粪和猪粪作为鲤鱼（Cyprinus carpio）补充饲料的毒性作用进行了测试。急性毒性试验表明，动物粪便的毒性比活性污泥更大（例如，猪粪和鸡粪的96小时半数致死浓度分别为0.55%和0.29%，而活性污泥未显示有效数值）。这可能是由于粪便处理不当，导致在分解过程中释放出有害物质。总体而言，在养殖期间，所有投喂这些废弃物的鱼的体重都有所下降。在投喂废弃物的鱼的鱼肉中发现积累了高浓度的重金属（铅、铜、锌和锰）。建议在将废料用作动物饲料之前对其进行预处理和解毒。
