“…(Bartos et al, 2008;Bonjar, 2004). Recently, it has been reported that the presence of fuel ethers like ethyl tert-butyl ether (ETBE) and tert-amyl methyl ether (TAME) may have an inhibitory effect on nitrification in contaminated soil samples (Bartling et al, 2010). This hypothesis was based on previous studies, which showed the effect of dimethylether on Nitrosomonas europaea, a member of one of the major nitrifying microorganism groups in soils.…”

Inhibition of nitrification in the presence of low oxygen concentrations (below 1.2 mg/L) and temperature dependency at oxygen saturation levels were observed in an aerated treatment pond system with biofilm promoting mats in two parallel ponds for remediation of ammonium, methyl tertiary butyl ether (MTBE), and benzene-contaminated groundwater. Within the first 18 months, at an average oxygen concentration of 0.7 ± 0.5 mg/L along the ponds, no significant decrease of ammonium or significant formation of nitrification products were observed. After increasing the aeration to oxygen saturation levels, the ammonium removal increased up to a maximum of 27%, with concomitant formation of nitrite and nitrate (up to 26 and 0.6 mM). The subsequent reduction of aeration in one pond to the previous level resulted in a definitive stop of nitrification, while, in the other pond, nitrification was well-correlated with the water temperature, reaching up to 45% ammonium removal.

“…Soil samples were contaminated with 5 ml (equivalent to 6.76 g) kg −1 m −1 d ETBE (Merck, Germany), respectively 5 ml (equivalent to 6.41 g) kg −1 m −1 d TAME (Sigma-Aldrich, Germany). These concentrations have been proven to affect soil microflora and fauna [16,22] and additionally, they reflect typical levels of contamination at field sites. Control soil samples received 5 ml water.…”

The oxidation of ethyl tert-butyl ether (ETBE), a widely used fuel oxygenated additive, is investigated using Cl atoms as initiators in the presence of oxygen. The reaction is carried out at 293, 550, and 700 K. Reaction products are probed by a multiplexed chemical kinetics photoionization mass spectrometer coupled with the synchrotron radiation produced at the Advanced Light Source (ALS) of the Lawrence Berkeley National Laboratory. Products are identified on the basis of mass-to-charge ratio, ionization energies, and shape of photoionization spectra. Reaction pathways are proposed together with detected primary products.
