Description | Ethylbenzene, also known as ethylbenzol or phenylethane, belongs to the class of organic compounds known as benzene and substituted derivatives. These are aromatic compounds containing one monocyclic ring system consisting of benzene. Chronic exposure to etylbenzene can lead to an increase in the mean number of lymphocytes and a decrease in hemoglobin levels. Ethylbenzene is possibly neutral. Outside of the human body, Ethylbenzene is found, on average, in the highest concentration within black walnuts and safflowers. Ethylbenzene has also been detected, but not quantified in, several different foods, such as garden tomato (var.), cauliflowers, cucumbers, cherry tomato, and garden tomato. This could make ethylbenzene a potential biomarker for the consumption of these foods. This aromatic hydrocarbon is important in the petrochemical industry as an intermediate in the production of styrene, which in turn is used for making polystyrene, a commonly used plastic material. Ethylbenzene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Treat dermal irritation or burns with standard topical therapy. |
