Dechlorination of pcb
WebMicrobial reductive dechlorination is a major degradation pathway of chlorinated hydrocarbon in anaerobic subsurface environments, has been extensively studied. Recent progress on the diversity... WebThe naturally occurring dechlorination unfortunately has a number of short-comings: 1) the transformation rate is extremely slow, especially at lower PCB levels such as those found in the New York/New Jersey Harbor, and 2) the presence of sulfate in marine sediments may inhibit dechlorination.
