包括氯氟烃(CFCs)在内的卤化C2和C2脂肪族化合物(HAC)是影响平流层臭氧水平的最重要的痕量气体之一，也是温室效应的贡献者。HAC是从危险废物场所排放到大气中的最常见的化学品之一。虽然曾经被认为抵抗水生和陆地过程的转变，但现在已知发生了这样的转变。非生物和微生物代谢过程可以并行或顺序地转化多种HAC，包括CFC-11、CFC-12、CFC-113、1，1，1-三氯乙烷、四氯化碳和三氯乙烯。速率和途径取决于化学结构和物理化学和生物地球化学条件。就对全球分布的影响而言，这些比率的重要性尚不清楚。
Halogenated C1and C2aliphatic compounds (HACs) including chlorofluorocarbons (CFCs) are among the most important trace gases affecting stratospheric ozone levels and are contributors to the greenhouse effect. HACs are among the most frequently found chemicals emanating from hazardous waste sites into the atmosphere. Although once believed to be resistant to transformation by aquatic and terrestrial processes, such transformations are now known to occur. Abiotic and microbial metabolic processes can transform in parallel or sequentially a wide range of HACs including CFC-11, CFC-12, CFC-113, 1,1,1-trichloroethane, carbon tetrachloride, and trichloroethylene. Rates and pathways depend on chemical structure and physico-chemical and biogeochemical conditions. The significance of such rates in terms of effect on global distributions is not known.
