Reductive dechlorination of DDT to DDD by rat blood

Dechlorination of DDT, DDD and DDE in soil (slurry) phase using magnesium/palladium system.

Mg0/Pd4+ was able to dechlorinate >99% of extractable DDT (initial concentration of 10 mg DDT kg(-1) of soil) and >90% of extractable DDT (initial concentration of 50 mg DDT kg(-1) of soil) in soil slurry. Mg0/Pd4+ was also found to be effective in dechlorinating of 50 mg kg(-1) DDD and DDE, in soil aged for varying time periods. GC-MS analyses revealed the formation of 1,1-diphenylethane as an...

Reductive metabolism of p,p'-DDT and o,p'-DDT by rat liver cytochrome P450.

The in vitro metabolism of p,p'-DDT [1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane], an important environmental pollutant, was examined in rat liver, focusing on reductive dechlorination. When p,p'-DDT was incubated with liver microsomes of rats in the presence of NADPH or NADH, a dechlorinated metabolite, p,p'-DDD [1,1-dichloro-2,2-bis(4-chlorophenyl)ethane], was formed under anaerobic conditi...

Kinetics of Reductive Dechlorination of Trichloroethane (TeA) by Anaerobic Biofilms

Abiotic reductive dechlorination of chlorinated ethylenes by soil.

Abiotic reductive dechlorination of chlorinated ethylenes by soil in anaerobic environments was characterized to improve knowledge of the behavior of chlorinated ethylenes in natural systems, including systems modified to promote attenuation of contaminants. Target organics in the soil suspension reached sorption equilibrium in 2 days and the sorption isotherm of target organics was properly de...
