In situ transformation of deuterated toluene and xylene to benzylsuccinic acid analogues in BTEX-contaminated aquifers.
Techniques for detecting and quantifying anaerobic transformations of benzene, toluene, ethylbenzene, and xylene (BTEX) are needed to assess the feasibility of using in situ bioremediation to treat BTEX-contaminated groundwater aquifers. Deuterated surrogates of toluene (toluene-d8) and xylene (o-xylene-d10) were injected into BTEX-contaminated aquifers during single-well push-pull tests to mon...
متن کاملOccupational exposure of gasoline station workers to BTEX compounds in Bangkok, Thailand.
BACKGROUND Gasoline station workers are exposed to volatile organic compounds such as benzene, toluene, ethylbenzene and xylene (BTEX). OBJECTIVE To determine the level of exposure to BTEX compounds among gasoline station workers and measure the roadside concentrations of these compounds in the inner and outer areas of Bangkok, Thailand. METHODS 49 workers at 6 gasoline stations in the inne...

متن کاملEffect of BTEX and Ethanol on Biodegradation of MTBE
Methyl-tert-butyl (MTBE) is widely used in gasoline to reduce ozone and carbon monoxide emissions. However, it is highly water-soluble and does not absorb well to sediments, making it move quickly through groundwater systems. In addition, MTBE resists biological degradation, compared to other gasoline components, probably because of the high energy required to cleave its ether bond. The contami...
متن کاملFate of gasoline oxygenates in conventional and multilevel wells of a contaminated groundwater table in Düsseldorf, Germany.
In a gasoline-contaminated site in Düsseldorf, Germany a two-year monitoring program was carried out to determine the presence, behavior, and fate of 12 gasoline additives in a total of 96 samples from 14 groundwater wells. The origin of contamination was suspected to be a gasoline spill at a gas station. Target compounds were methyl-tert-butyl ether (MTBE), its main degradation products, tert-...
