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.

在土壤微观世界和富集培养物中鉴定十氯酮的完全脱氯产物

用来自瓜德罗普岛的土壤构建的厌氧微观世界，用乙醇和丙酮修正并厌氧培养十多年，将十氯酮 (CLD) 转化为一套逐渐脱氯的产品，包括完全脱氯的羧化茚产品。这种完全脱氯的转化产物以前从未被观察到，这表明 CLD 的完全脱氯是可能的。通过 LC-MS 检测羧化茚，并使用 Q-Exactive Orbitrap 质谱仪通过 LC-MS/MS 确认结构。
