摘要
氟里昂替代品在大气中的降解反应将产生大量的三氟乙酸，其在大气中可与ＯＨ 自由基反应生成三氟甲烷和二氧化碳，主要的去除机制是沉降和雨除，并在地面水中累积；
The atmospheric degradation of CFC replacements is major source for trifluoroacetate, which may react on OH radical and was wiped off by settlement and rainout mechanism. It is possible that trifluoroacetate will accumulate in wetlands and bring impact to environment.
