Anaerobic microcosms constructed with soil from Guadeloupe, amended with ethanol and acetone and incubated anaerobically for more than a decade, transformed chlordecone (CLD) into a suite of progressively more dechlorinated products, including a fully dechlorinated carboxylated indene product. This fully dechlorinated transformation product has never before been observed and indicates that complete dechlorination of CLD is possible. The carboxylated indene was detected by LC-MS, and structure was confirmed by LC-MS/MS using a Q-Exactive Orbitrap mass spectrometer.
