The use of impervious gloves and masks, along with respirators where appropriate, is recommended to avoid occupational health issues from xylene exposure. [20] Xylenes are metabolized to methylhippuric acids. [28] [29] The presence of methylhippuric acid can be used as a biomarker to determine exposure to xylene. [29] [30]
Exposure to xylene comes in two main forms: vapor and liquid. Breathing in xylene is the most common form of exposure. Small amounts of xylene vapors can cause headaches, dizziness, drowsiness and ...
Exposure of p-xylene through the skin can cause dry skin and redness. If skin exposure occurs, first aid includes rinsing and then washing the affected area with soap and water as well as removing any contaminated clothing and thoroughly cleaning and drying before reuse. Exposure can be prevented through the use of protective gloves. [17]
o-Xylene (ortho-xylene) is an aromatic hydrocarbon with the formula C 6 H 4 (CH 3) 2, with two methyl substituents bonded to adjacent carbon atoms of a benzene ring (the ortho configuration). It is a constitutional isomer of m -xylene and p -xylene , the mixture being called xylene or xylenes.
Methylhippuric acid is a carboxylic acid and organic compound. Methylhippuric acid has three isomers. The isomers include 2-, 3-, and 4-methylhippuric acid. [1]Methylhippuric acids are metabolites of the isomers of xylene.
m-Xylene (meta-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes . The m- stands for meta- , indicating that the two methyl groups in m -xylene occupy positions 1 and 3 on a benzene ring.
Likewise, the para-xylene consumption showed unprecedented growth in 2010, growing by 2,800,000 tons, a full ten percent growth from 2009. [1] Toluene is also a valuable petrochemical for use as a solvent and intermediate in chemical manufacturing processes and as a high octane gasoline component. [2] [3] [4] [5]
Hippuric acid has long been used as an indicator of toluene exposure; [14] however, there appears to be some doubt about its validity. [15] There is significant endogenous hippuric acid production by humans; which shows inter- and intra-individual variation influenced by factors such as diet, medical treatment, alcohol consumption, etc. [15] This suggests that hippuric acid may be an ...
