Exposure to aniline may occur from breathing contaminated
outdoor air, smoking tobacco, or working or being near
industries where it is produced or used. The acute (short-
term) and chronic (long-term) effects of aniline in humans
consist mainly of effects on the lung, such as upper
respiratory tract irritation and congestion. Chronic exposure
may also result in effects on the blood. Human cancer data are
insufficient to conclude that aniline is a cause of bladder
tumors while animal studies indicate that aniline causes tumors
of the spleen. EPA has classified aniline as a Group B2,
probable human carcinogen.
