Hexachlorobenzene dechlorination as affected by nitrogen application in acidic paddy soil

Short-term enhancement effect of nitrogen addition on microbial degradation and plant uptake of polybrominated diphenyl ethers (PBDEs) in contaminated mangrove soil

“…were reported to couple their growth to the dechlorination of PCBs and pentachlorophenol (PCP) [33,34]. In this study, consistent patterns of variation were found between the abundances of these two dehalogenating bacteria and PBDE removal rate in mangrove soil could adjust the soil C/N ratio to a more suitable level for the activity of dehalogenating bacteria [33,36].…”

Electron Donor Substances and Iron Oxides Stimulate Anaerobic Dechlorination of DDT in a Slurry System with Hydragric Acrisols

“…1). The CH 4 generation combined with anaerobic degradation of organic C may have competed with reductive dechlorination for electrons (Brahushi et al, 2004; Liu et al, 2010b). There are several important reductive reactions in the present anaerobic systems, such as CH 4 formation, Fe(III) reduction, and reductive dechlorination.…”

Hexachlorobenzene dechlorination in constructed wetland mesocosms

“…3aec). This fact might demonstrate an efficient degradation of metabolites which does not allow their accumulation in substrate like it was found in experiments conducted by Liu et al (2010). This is also beneficial regarding both Phragmites and Typha plants for which the dechlorinated w a t e r r e s e a r c h 4 7 ( 2 0 1 3 ) 1 0 2 e1 1 0 metabolites are toxic (Ma and Havelka, 2009).…”

“…Considering literature values, this concentration is at medium level (see high initial concentrations of 15,000 and 30,000 mg/kg HCB in Zhou et al, 2012, and low initial concentration of 1980 mg/ kg according to Liu et al, 2010) and is optimal regarding the relatively short-term dynamics of dechlorination process. Six MC containers were filled with a 10 cm layer of gravel (15e25 mm) at the bottom followed by 50 cm layer of sediment and an HCBequartzesand mixture as an active filter, and finally filled with tap so that 10 cm water layer stayed in the top of the filter (Fig.…”
