BTEX pollution caused by motorcycles in the megacity of HoChiMinh

Journal of Environmental Sciences, 2013
Monitoring of benzene, toluene and xylenes (BTEX) was conducted along with traffic counts at 17 roadside sites in urban areas of HoChiMinh. Toluene was the most abundant substance, followed by p,m-xylenes, benzene, o-xylene and ethylbenzene. The maximum observed hour-average benzene concentration was 254 microg/m3. Motorcycles contributed to 91% of the

Potential for activated persulfate degradation of BTEX contamination

Water Research, 2008
The present study focused on evaluation of activated persulfate (PS) anion (S(2)O(8)(2-)) oxidative degradation of benzene, toluene, ethylbenzene, and xylene (constituents of gasoline and known collectively as BTEX) contamination. The results indicated that BTEX were effectively oxidized by PS in aqueous and soil slurry systems at 20 degrees C.

Airborne particulate matter and BTEX in office environments

Journal of Environmental Monitoring, 2008
Total suspended particulate (TSP), PM(2.5) and BTEX were collected in nine offices in the province of Antwerp, Belgium. Both indoor and outdoor aerosol samples were analysed for their weight, elemental composition, and water-soluble fraction. Indoor TSP and PM(2.5) concentrations ranged from 7-31 microg m(-3) and 5-28 microg m(-3), with an average of ...

In Vitro Cytotoxicity of BTEX Metabolites in Hela Cells

Archives of Environmental Contamination and Toxicology, 1998
Fuel leakage from underground storage tanks is a major source of groundwater contamination. Although the toxicity of regulated compounds such as benzene, toluene, ethylbenzene, and xylene (BTEX) are well recognized, the cytotoxicity of their metabolites has not been studied extensively.

Alternative primer sets for PCR detection of genotypes involved in bacterial aerobic BTEX degradation: Distribution of the genes in BTEX degrading isolates and in subsurface soils of a BTEX contaminated industrial site

Journal of Microbiological Methods, 2006
Eight new primer sets were designed for PCR detection of (i) mono-oxygenase and dioxygenase gene sequences involved in initial attack of bacterial aerobic BTEX degradation and of (ii) catechol 2,3-dioxygenase gene sequences responsible for meta-cleavage of the aromatic ring.

Sorption of BTEX mixtures to organobenonites.

Journal of environmental sciences (China), 2004
Organobentonites synthesized by replacing the metal ions in bentonite with cetyltrimethylammonium (CTMA) or tetramethylammonium cation (TMA) were investigated for their behaviors to sorb benzene, toluene, p-xylene from water. The results served to distinguish the sorption mechanisms (adsorption or partition) of the two types of organobentonites ...

The Fate of BTEX Diluted in the Macondo Blowout

2018
The following paper presents the results of blowout numerical modeling formulated in Eulerian coordinates with a special emphasis on the 3D distribution of diluted benzene, toluene, ethylbenzene, and xylene (BTEX). The Eulerian approach is applied only to the liquid phase of a stratified water column with 3D dynamics.
