Concentrations of the halocrbons CCl(3)F (F-11), CCl(2)F(2) (F-12), CCl(4), and CH(3)CCl(3), methane (CH(4)), and nitrous oxide (N(2)O) over the decade between 1975 and 1985 are reported, based on measurements taken every January at the South Pole and in the Pacific Northwest. The concentrations of F-11, F-12, and CH(3)CCl(3) in both hemispheres are now more than twice their concentrations 10 years ago. However, the annual rates of increase of F-11, F-12, and CH(3)CC1(3) are now considerably slower than earlier in the decade, reflecting in part the effects of a ban on their nonessential uses. Continued increases in these trace gas concentrations may warm the earth and deplete the stratospheric ozone layer, which may cause widespread climatic changes and affect global habitability.
报告了 1975 年至 1985 年这十年间在南极和太平洋西北地区每个 1 月测量得到的卤代烃 CCl(3)F（F-11）、CCl(2)F(2)（F-12）、CCl(4)和 CH(3)CCl(3)、甲烷（CH(4)）和氧化亚氮（N(2)O）的浓度。现在，这两个半球的 F-11、F-12 和 CH(3)CCl(3)浓度是 10 年前的两倍多。然而，F-11、F-12 和 CH(3)CC1(3)的年增长率现在比十年前要慢得多，这部分反映了禁止其非必要用途的影响。这些痕量气体浓度的持续增加可能会使地球变暖，消耗平流层臭氧，这可能会导致广泛的气候变化，并影响全球可居住性。
