The pure trichloroethene
(TCE, >99.0), cis-1,2-dichloroethene (cis-1,2-DCE, >99.0%), 1,1,1-trichloroethane (TCA, >94.0%), and 1,2-dichloroethane (1,2-DCA, >99.0%) were purchased from Sinopharm Chemical Reagent Co., Ltd, and diluted to the certain concentration for each experiment.

hydrodechlorination," Applied Catalysis B: Environmental, vol.
The starting point for this theory was their discovery in the south of Russia and South Africa that microbial processes in present-day salt lakes naturally produce and emit highly volatile halocarbons such as chloroform, trichloroethene
, and tetrachloroethene.
Squire says environmental toxins may be to blame, including mercury found in fish, TCE (trichloroethene
) found in the factory where the victim worked, and PCBs (poly-chlorinated biphenyls) found in groundwater and fish.

Duhamel M, Wehr S, Yu L, Rizvi H, Seepersad D, Dworatzek S, Cox E, Edwards E (2002) Comparison of anaerobic dechlorinating enrichment cultures maintained on tetrachloroethene, trichloroethene
, cis-dichloroethene and vinyl chloride.
Hundreds of sites across the United States contain trichloroethene
(TCE) contamination, including the Department of Energy's Savannah River Site (SRS) in Aiken, South Carolina.
Similarly, while DOE's pilot test of a new technology for removing the hazardous chemical trichloroethene
(TCE) from groundwater at the site had promising results--removing about 99 percent of the TCE in the test zone--the technology will not be fully implemented for more than a year.
The pesticide of greatest concern was aldicarb; the most common VOCs were tetrachloroethene (PCE), trichloroethene
(TCE), 1,1,1 trichloroethane (TCA), and 1,2 dichloropropane (DCP).
A plume of the solvent trichloroethene
(TCE) has spread under a section of downtown Orlando, where water below other properties also is being tested.
