The toxicity of aniline to rainbow trout

The acute lethal toxicity of aniline to rainbow trout was assessed, the fish being exposed for a maximum period of 1 week. The 7-day median lethal concentration was 8.2 mg l^?1 and the concentration/survival time relation was rectilinear over the period. A limited investigation into the physiological fate of the aniline is described; the amine moiety is detached and excreted as ammonia.The mammalian toxicology of aniline and mutagenic and teratogenic effects on fish ova, are reviewed.
