In feeding experiments with pigs and fish (carp and trout) the test animals received quotas of activated sludge of 7.5 and 15% DM (pigs) and 20% (carp) in their mixed feed. In an experiment with trout in an aquarium the quota of activated sludge was increased from 20% to 50%. The benzo(a)pyrene content was ascertained in selected organs of the pigs (kidney, liver, bacon, muscles) and the edible parts of the fish. As a result of this experiment one can say that the feeding of activated sludge from pig manure does not result in an increased benzo(a)pyrene content in the tested organs of the pigs and the edible parts of the fish.
在猪和鱼（鲤鱼和鳟鱼）的饲养实验中，实验动物在其混合饲料中摄入了占干物质7.5%和15%（猪）以及20%（鲤鱼）的活性污泥配额。在一项针对水族箱中鳟鱼的实验中，活性污泥配额从20%提高到了50%。测定了猪的选定器官（肾脏、肝脏、培根、肌肉）以及鱼的可食用部分中的苯并(a)芘含量。该实验结果表明，投喂猪粪活性污泥不会导致猪的受试器官和鱼的可食用部分中苯并(a)芘含量增加。
