平流层中臭氧的总量相对较低：如果可以在大气压下收集和压缩，整个层的厚度约为3或4毫米。因此，气体污染物，如人造氯氟化碳（CFC），尽管排放量相对较小（每年超过100万吨），但会影响臭氧密度。氯原子从氯氟烃中释放出来，并催化分解数千个臭氧分子，直到它们被从大气中冲洗出来。
The total amount of ozone in the stratosphere is comparatively low: if it could be collected and compressed under atmospheric pressure, the thickness of the whole layer would amount to about 3 or 4 mm. Therefore it is not astonishing that gaseous pollutants such as man-made chlorinated fluorocarbons (CFC)?, even though emitted in relatively small amounts (exceeding 1 million tons per year), affect the ozone density. The chlorine atoms are liberated from the CFCs and catalytically break down many thousand ozone molecules each until they are washed out of the atmosphere.
