POLYcYcLIac aromatic hydrocarbons are known to produce two distinct pathological changes in animals. Thus under certain conditions naphthalene produces cataract in rabbits, whilst under other conditions derivatives of 1:2-benzanthracene produce cancer in some species. It is possible that animals might deal with toxic hydrocarbons in either of two ways; the compounds might either be converted in...
