Sources & Potential Exposure
4-Nitrophenol is used to manufacture drugs, fungicides, insecticides, and dyes and to darken leather. Acute (short-term) inhalation or ingestion of 4-nitrophenol in humans causes headaches, drowsiness, nausea, and cyanosis (blue color in lips, ears, and fingernails). Contact with eyes causes irritation in humans. No information is available on the chronic (long-term) effects of 4-nitrophenol in humans or animals from inhalation or oral exposure. No information is available on the reproductive, developmental, or carcinogenic effects of 4-nitrophenol in humans. No information is available on the levels of 4-nitrophenol in ambient air or in food, and 4-nitrophenol has not been detected in drinking water. (1) Occupational exposure to 4-nitrophenol may occur for those workers involved in the manufacture or use of 4-nitrophenol.
EPA has not classified 4-nitrophenol for potential carcinogenicity.
