在过去的几十年里，作为喷雾器推进剂溶剂的氯氟烃的生产呈指数级增长。R. L.麦卡锡（未发表）估计，1971年中期，该类别的两种主要化合物CCl 2F 2和CCl 3F的综合产量约为100万吨;它们在化学上异常稳定，仅微溶于水，因此可能在大气中持续存在并积累。1970年的初步测试表明，爱尔兰上空的空气中含有四氯化碳，浓度超过10−11（体积）。
DURING the past few decades the production of the chlorofluorocarbons, the propellant solvents for aerosol dispensers, has grown exponentially. R. L. McCarthy (unpublished) estimates that the integrated production of CCl2F2 and of CCl3F, the two principal compounds of the class, was about one megaton of each in mid 1971; they are unusually stable chemically and only slightly soluble in water and might therefore persist and accumulate in the atmosphere. Preliminary tests in 1970 showed that CCl3F was present in the air over Ireland at concentrations exceeding 10−11 by volume1.
