P ksylen
WebXylene, xylol, or dimethylbenzene is known to cause severe vasodilation and edematous changes of skin as signs of acute inflammation (Tang et al., 1984 ). The increased thickness of ear tissues is caused by these histopathological changes. After topical application of xylene, severe vasodilation and edematous changes of the skin occur, and ... WebXylene exists as three isomers (ortho-, meta-, and para-xylene), which can be found singly or, more commonly, mixed in varying proportions. Commercial grade xylene, in which m-xylene is usually the major constituent, is a clear, colorless liquid with a sweet, aromatic odor. It is generally referred to as Mixed, Total or Technical-Grade Xylene.

WebIn this report, the terms xylene, xylenes, and total xylenes will be used interchangeably. There are three forms of xylene in which the methyl groups vary on the benzene ring: meta-xylene, ortho-xylene, and para-xylene (m-, o-, and p-xylene). These different forms are referred to as isomers. The term total xylenes refers to all three isomers of xylene (m-, o …
