Webcontaminants. For example, 1 ounce of trichloroethylene (TCE) in 1 million ounces of water is 1 ppm. 1 ounce of TCE in 1 billion ounces of water is 1 ppb. If one drop of TCE is mixed in a competition size swimming pool, the water will contain about 1 ppb of TCE. Plume An area of contaminants in a specific media such as groundwater. Webmonoxide. As the degradation products of TCE by toluene dioxygenase are formic acid and glyoxylic acid, the degradation pathways might be diŠerent from the monooxygenase pathway.7) In earlier studies we isolated the ethane-utilizing bacterium, Mycobacterium sp. TA27, which can co-metabolicallydegrade TCE and TCA.15–17) Only a few
