At an exposure of 100 ppm, one may experience nausea or a headache. At an exposure between 200 and 500 ppm, symptoms can include feeling "high", dizziness, weakness, irritability, vomiting, and slowed reaction time. [20] [21] The side effects of exposure to low concentrations of xylene (< 200 ppm) are reversible and do not cause permanent ...

Xylene also is used in the plastics, chemical and synthetic fiber industries. As a vapor, xylene is heavier than air, so it will rest in low-lying areas. It easily evaporates, so if it enters the ...
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. o-Xylene is a colourless slightly oily flammable ...
p-Xylene (para-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes . The p- stands for para- , indicating that the two methyl groups in p -xylene occupy the diametrically opposite substituent positions 1 and 4.

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.
