Although hexachlorobutadiene (HCBD) was recently proposed as a candidate persistent organic pollutant (POP) under the Stockholm Convention, information about its environmental levels and distributions is still very limited. In this work, HCBD was determined in the sewage sludge from 37

Palladium-catalyzed hydrodehalogenation (HDH) was applied for destroying 1,2,4,5-tetrachlorobenzene (TeCB) in mixtures of water and ethanol. This investigation was performed as a critical step in the development of a new technology for clean-up of soil contaminated by halogenated hydrophobic organic contaminants.

The bacterium, Burkholderia (previously Pseudomonas) sp. strain PS12, reported earlier to degrade 1,2,4-trichlorobenzene is shown here to utilize also 1,2,4,5-tetrachlorobenzene (Cl4-benzene) as a growth substrate. To investigate the possibility that this organism attacks Cl4-benzene with a chlorobenzene dioxygenase which concomitantly

1,2,4,5-Tetrachlorobenzene (TCB) is an industrial intermediate used in the production of 2,4,5-trichlorophenoxyacetic acid.
