Anaerobic microcosms constructed with soil from Guadeloupe, amended with electron donor (ethanol and acetone) and incubated 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.

在土壤微观和富集培养中鉴定十氯酮完全脱氯的产物

用瓜德罗普岛的土壤建造的厌氧微观世界，用电子供体（乙醇和丙酮）进行了改良，并孵育了十多年，将十氯酮（CLD）转化为一系列逐步脱氯的产品，包括完全脱氯的羧化茚产品。从未观察到这种完全脱氯的转化产物，这表明CLD可以完全脱氯。通过LC-MS检测羧基化的茚，并使用Q-Exactive Orbitrap质谱仪通过LC-MS / MS确认结构。
