According to the articles selected in this review, toluene is considered ototoxic and thought to damage the OHC in the middle region of the cochlea, with evidence of an interaction with noise, whereas ethylbenzene and xylenes
can be considered potentially ototoxic according to animal studies, in which lesions/ losses of OHC have also been observed.

Ceresana expects global demand for xylenes
to increase considerably in the future: Aggregated consumption of p-, o- and m-xylene will rise by about 4.5% p.a.
The next heavier aromatic, xylene
or C8, comes in three differently shaped isomers and so does the next heavier one, mesitylene or C9.
Data of this table shows that the unloaded zeolite is significantly less active for xylenes
The company said that its Packinox heat exchangers will be used in the catalytic processing sections in the production of mixed Xylenes
used for products such as synthetic nylons and PET bottles.
The primary contaminants of concern at the site were volatile organic compounds (VOCs), including benzene, ethylbenzene, and xylenes
, which can pose significant risks to people's health.
Volatile aromatic hydrocarbons BTEX in unleaded gasoline contain benzene, toluene, ethylbenzene and xylenes
in concentration above 10,000 ppm for each compound in the ratio (1:5:1:5).

Those in the second cover filtration, flocculation, flotation, fractionation, foam, gas-solid separation, high purity gases, ion exchange, isotope separation, magnetic separation, mass transfer, membrane technology, metals separation, microfluidics, minerals recovery and processing, molecular sieves, nuclear fuel reprocessing, petroleum refining, process integration technology, sedimentation, separations process synthesis, silica gel, size separation, stack gases, sulfur and hydrogen sulfide recovery, supercritical fluids, wastewater treatment, water desalination, water treatment, and xylenes
Naftec and ENIP have aromatics units at the Skikda oil refining complex with a capacity to produce: 90,000 t/y of benzenes, about 5,000 t/y of toluenes, 247,000 t/y of xylenes
, and 38,000 t/y of paraxylenes.
Among the pollutants emitted are ethylene glycol monobutyl ether (EGBE) and other glycol ethers, xylenes
Isobaric vapor-liquid equilibria for ternary mixtures: saturated hydrocarbons, xylenes
, and ethylbenzene with sulfolane at 101.325 kPa.
