As the main ozone depleting compounds, the abundance of CFCs in the troposphere and stratosphere has been focused on all the while. However, there are few reports concerning on the distribution of the CFCs varying with the latitude. Relying on the long-term monitoring we have performed in Shanghai from 1997 and Cooperating with the Chinese Third Antarctic Inland Ice-sheet Traversal Party, we did intensive sampling in the Southern Hemisphere from the beginning of November to the end of December in 1998, and then got the corresponding concentrations of CFC-12, CFC-11 and CFC-113 according to the latitude after analysis. Basing on them, we did inductive study on the data in accordance with the geographical location and meteorological condition of every sampling point. Compared with the mean background of the Southern Hemisphere, the concentrations in Shanghai bear the same level, which predicate that the CFCs' release in China remains low comparatively.
