Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Several chloroalkyl intermediates formed during the reaction between tetrachloroethylene and aquocobalamin were identified by direct liquid injection in an Electrospray LC/MS. The concurrent presence of all reaction intermediates when combined with information on the dechlorination products formation, lead to a revised scheme on the possible pathways of the reductive dechlorination reaction catalysed by cobalamins (such as vitamin B 12). The new proposed pathways involve reductive dechlorination occurring on the alkyl cobalamins, and homolytic cleavage and titanium catalysed elimination as competing mechanisms for the formation of the products from the alkylcobalamin intermediates"--Abstract. gccst Water management gccst Groundwater gccst Pollutants Brown, Susan, author.
