Aromatic amines and nitro compounds are used extensively in many industries and because many of these compounds are known or suspected carcinogens they are becoming of increasing concern as environmental pollutants. Although the exact mechanism of the carcinogenic effects of these compounds is not yet fully understood, N-hydroxylation is regarded as an essential step. N-hydroxylated amines are known to be formed metabolically but it is not yet known if N-hydroxylation occurs in the environment or if the arylhydroxylamines are environmentally stable. The authors research focused on the environmental formation of N-hydroxylamines, specifically the formation of N-hydroxy-o-toluidine via the photooxidation in water of o-toluidine or the reduction in soil of 2-nitrotoluene. The photooxidation and reduction products were identified and the rates of formation and stabilities of the major products determined. N-hydroxy-o-toluidine was shown to be unstable in aqueous environments, oxidizing to 2-nitrosotoluene within 24 hours.
