Volatile Organic Compounds (VOCs) in presence of sunlight and oxides of nitrogen in atmosphere are considered as precursors for ozone production at the ground level. Concentration of Benzene, Toluene and Xylene (BTX) in aient air was measured near …
Xylene vapor is heavier than air and may cause asphyxiation in enclosed, poorly ventilated, or low-lying areas. Children exposed to the same levels of xylene vapor as adults may receive a …
Oxidation Process of Xylene in Air Under Electron Beam Irradiation with TiO2 and Ag/TiO2. Abstract: Oxidation of xylene and its organic irradiation byproducts in air using plasma-driven …
28/10/2015· Xylene vapour is rapidly absorbed through the respiratory tract. It is also absorbed by skin contact, and penetrates many materials used for protective clothing. Over 90% of the absorbed dose is metabolised and excreted in the urine as methyl hippuric acid. A small proportion (5%) is exhaled in the breath. HEALTH EFFECTS Animal studies
Xylene in air can be smelled at concentrations as low as 0.08 to 3.7 ppm (parts of xylene per million parts of air) and can begin to be tasted in water at 0.53 to 1.8 ppm. The xylenes are major petrochemicals, produced by alytic reforming and also …
The term xylene or xylol refers to a mixture of three structural isomers of the aromatic hydrocarbon dimethylbenzene. Xylene is a clear, colorless, sweet-smelling liquid that is very …
DOI: 10.1007/s00216-004-2837-1 Abstract The aim of the study was to analyse BTEX compounds (benzene, toluene, ethylbenzene, xylenes) in air by solid phase micro-extraction/gas chromatography/mass spectrometry (SPME/GC/MS), and this article presents the features of the calibration method proposed. Examples of real-world air analysis are given.
1/5/2016· Air Quality, Atmosphere & Health 2014 The benzene, toluene, ethylbenzene, and xylene (BTEX) compounds are egorized as volatile organic compounds (VOCs) that may contribute to the formation of ground-level ozone and photochemical smog,… Expand 90

Oxidation Process of Xylene in Air Under Electron Beam Irradiation with TiO2 and Ag/TiO2 Abstract: Oxidation of xylene and its organic irradiation byproducts in air using plasma-driven alyst (PDC: TiO 2 and Ag/TiO 2 ) pellet layers was …
Xylene vapor is heavier than air and may cause asphyxiation in enclosed, poorly ventilated, or low-lying areas. Children exposed to the same levels of xylene vapor as adults may receive a larger dose because they have greater lung surface area:body weight ratios and increased minute volumes:weight ratios. In addition, they may be exposed to
10/2/2021· For example, fresh food like fruits and vegetables might be exposed to xylenes due to environmental contaminants in the soil, water or air. Some food items that have been found to contain trace amounts of xylenes and other aromatic hydrocarbons include: Meat products (31 µg/kg) Poultry (33 µg/kg) Eggs (7 µg/kg) Milk (4 µg/kg) Bread (9 µg/kg)
Xylene is also found in gasoline and aviation fuels. It is used in the manufacture of plastics, synthetic textiles, perfumes, insect repellants, epoxy resins, herbicides and pharmaceutical preparations. B) TOXICOLOGY: Xylene is an aromatic hydrocarbon solvent that causes CNS depression and is an irritant of skin and mucus meranes.
Vapors may form explosive mixtures with air. Containers may explode when heated. May polymerize explosively when heated. An attempt to chlorinate xylene with 1,3-Dichloro-5,5-dimethyl-2,4-imidazolidindione (dichlorohydrantoin) caused a violent explosion
Most people begin to smell xylene in air at 0.08–3.7 ppm (parts per million) and begin to taste it in water at 0.53–1.8 ppm. [ 1] Go to: TOXICITY OF XYLENE Exposure to xylene can occur via …
15/10/2022· The RIAQG propose short- and long-term indoor air exposure limits for xylenes, which would minimize risks to human health, and to support the development of actions to limit xylenes emissions indoors. The guideline document also recommends various risk mitigation measures to reduce exposure to xylenes. Sources and exposure
3/6/2015· Chronic human inhalation exposure to xylenes can cause kidney, liver, and nerve damage. It can also affect the central nervous system with symptoms such as headache, fatigue, dizziness, and memory loss (Gunathilaka 2003 ).

19/11/2022· Symptoms may include headache, nausea, dizziness, drowsiness and confusion. A severe exposure can cause unconsciousness. Skin Contact: SKIN IRRITANT. Causes moderate to severe irritation. Symptoms include pain, redness, and swelling. Can be absorbed through the skin, but harmful effects are not expected.

Over 90% of the absorbed dose is metabolised and excreted in the urine as methyl hippuric acid. A small proportion (5%) is exhaled in the breath. HEALTH EFFECTS Animal studies
The main effect of inhaling xylene vapour is depression of the central nervous system, with symptoms such as headache, dizziness, nausea and vomiting. The effects listed below can begin to occur with exposure to air levels of about 100 ppm. They are reversible and become more noticeable and serious as the length of time of exposure increases.
