toluene and o-xylene), it has been reported that the strong adsorption of benzaldehyde, benzene, and benzoic acid on the surface can lead to severe deactivation (Mo et al.
Vadoud Niri's 2016 research on plant VOC uptake at the State University of New York at Oswego (bit.ly/2zqDawF) examined the effectiveness of several species of air-purifying plants at removing eight compounds: benzene, toluene, ethylbenzene, p-xylene, o-xylene, acetone, dichloromethane (methylene chloride) and trichloromethane (chloroform).
However, m-xylene and o-xylene did not cause OHC loss, according to experiments with rats conducted by Gagnaire and Langlais [28].
We analyzed its molecular composition and compared the result with that of three other laboratories to confirm that it mainly contains 24 types of hydrocarbons: methane, ethane, propane, isobutane, M-butane, neopentane, isopentane, M-pentane, methyl cyclopentane, cyclohexane, 2-methylpentane, 3-methylpentane, M-hexane, 2,2/3,3-dimethyl pentane, methyl cyclohexane, 2/3-methyl hexane, 2,3-dimethyl pentane, M-heptane, benzene, M-octane, methyl benzene, M-nonane, ethylbenzene,p-xylene, and o-xylene. Several separate parallel samples were prepared from the in-lab standard natural gas for the experimental condition optimization.
The odor evaluation and the simultaneous identification via GC/MS-O allowed to identify 2-propanone, m,p-xylene, o-xylene, delta-3-carene, 1,2,3-trimethylbenzene, 1,3,5-trimethylbenzene, and ethyltoluene as the odor-active VOCs responsible for the overall perceived odor.
Anhydrous o-xylene supplied by Sigma Aldrich was used for gel content measurements.
Xylene exists as a clear liquid and can be found in three different isomeric forms: orthoxylene (o-xylene), metaxylene (m-xylene), and paraxylene (p-xylene).

Each isolates were inoculated to four different conical flasks with 100 mL of MSM containing 50mg/L of Benzene, Toluene, Ethyl benzene and o-Xylene (BTEX) added individually.
According to the US National Institute for Occupational Safety and Health (NIOSH), p,m-xylene may disturb the human central nervous and reproduction systems, o-xylene may damage the central nervous and hearing systems, toluene may adversely affect the human nervous system, and thus decrease the learning ability.
The concentrations of the following substances were measured in the operating room during laparoscopic surgery: benzene, toluene, ethylbenzene, p-xylene, o-xylene as well as dioxins and furans: 2,3,7,8-TCDD, 1,2,3,4,7,8-HxCDD, 1,2,3,4,6,7,8-HpCDD, OCDD, 2,3,7,8-TCDF, 1,2,3,6,7,8HxCDF, OCDF.
