The wide though not ubiquitous distribution of chlorobenzene-dechlorinating bacteria in anaerobic sludge from German sewage plants is demonstrated. The model substrates 1,2,3- and 1,2,4-trichlorobenzene (TCB) were dechlorinated to dichlorobenzenes (DCBs) and monochlorobenzene (MCB) via distinct pathways. For easy visualization and...

The use of a calibrated two-component model with a single blocking parameter for both adsorption onto mineral surfaces and partitioning into soil organic matter of two nonpolar sorbates (i.e., 1,2,4-trichlorobenzene and benzene) was evaluated by using several humic acid (HA)-coated...

The transcription of reductive dehalogenase homologous (rdh) genes of "Dehalococcoides" sp. strain CBDB1 was investigated during the growth and reductive dechlorination of 1,2,3- and 1,2,4-trichlorobenzene (TCB). A method was developed to monitor the expression of all 32 rdhA genes present...

Effects and kinetics of photocatalytic degradation of 1,2,4-trichlorobenzene with composite photocatalysts of TiO2 coated on carbon nanotubes and nano-TiO2 photocatalysts were studied, respectively. It was found that the composite photocatalysts was better than the nano-TiO2 for photocatalytic degradation of 1,2,4-trichlorobenzene....
