DescriptionXylenes are aromatic compounds that contain a benzene ring carrying two methyl groups at different positions (o-, m-, p-). Xylene is possibly neutral. In the plant kingdom xylene is found, on average, in the highest concentration in black walnuts. It has also been detected, but not quantified in several different foods, such as pepper (C. annuum), green bell peppers, parsley, yellow bell peppers, and red bell peppers. Exposure to xylene can occur via inhalation, ingestion, eye or skin contact. It is primarily metabolized in the liver by oxidation of a methyl group and conjugation with glycine to yield methyl hippuric acid, which is excreted in the urine. Smaller amounts are eliminated unchanged in the exhaled air (PMID: 21180450 ). If xylene is ingested one's mouth should be rinsed and vomiting should not be induced. Exposure of pure xylene to eyes can cause redness and pain. All xylene isomers are colorless and highly flammable.
