Description | Styrene, also known as vinylbenzene or phenylethylene, belongs to the class of organic compounds known as styrenes. These are organic compounds containing an ethenylbenzene moiety. The metabolites of styrene are excreted mainly in the urine. Styrene is possibly neutral. Styrene is a sweet, balsamic, and floral tasting compound. Styrene has been detected, but not quantified, in several different foods, such as coffee and coffee products, fruits, cocoa and cocoa products, alcoholic beverages, and chinese cinnamons. This could make styrene a potential biomarker for the consumption of these foods. A minor pathway of styrene metabolism involves the formation of phenylacetaldehyde from styrene 7,8-oxide or cytochrome P450 conversion of styrene to pheylethanol and subsequent metabolism to phenylacetic acid. Styrene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Styrene oxide is predominantly metabolized by epoxide hydrolase to form styrene glycol; the styrene glycol is subsequently converted to mandelic acid, phenylglyoxylic acid, and hippuric acid. Styrene, with regard to humans, has been found to be associated with several diseases such as nonalcoholic fatty liver disease and ulcerative colitis; styrene has also been linked to the inborn metabolic disorder celiac disease. Styrene may be absorbed following ingestion, inhalation, or dermal exposure. Breathing high levels of styrene may cause nervous system effects such as changes in color vision, tiredness, feeling drunk, slowed reaction time, concentration problems, or balance problems. Chest burning, wheezing, and dyspnea may also occur. Styrene causes nervous system depression and may be carcinogenic. |
