Untersuchungen zum Übergang von Benzo(a)pyren in tierische Organe nach Verfütterung von Überschußschlamm aus Schweinegülle

: 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.
