Determine the rate-limiting step in this reaction sequence and the fingerprint resulting from abiotic vs. biotic processes. Evaluate natural dechlorination rates and potential for enhancement in historically-contaminated sediment cores. Since octaCDD is usually most abundant in sediments, and both heptaCDD isomers can be produced after removal of one chlorine, the level of octaCDD indirectly affects 2,3,7,8-production. The hydrogen method has been filed as an invention disclosure with the University and is currently being tested on pulp and paper sludges.
Exceptions are environmental systems where humic-acid mediated reactions are dominant.
The rates were based on 25 g DW of sediments, and 5 mL of liquid for the sediment and solid-free systems, respectively.
