Abstract:

Testing of Antarctic acid rain (rain pH<5.6) can provide first handed information for test of change of global environment atmosphere chemistry, assessment of area environment and formation of environment standard,and it is important for understanding transmission, transformation and concentration of chemical elements in environment, it can also give insight in protection and reasonable development of Antarctic. We can know of the original of atmospheric chemistry environment through this test, and reasonable tactics can be made, as a result, the Antarctic can be protected effectively. The place of sample is Great Wall Station of China in Antarctica. The method to get the samples for this experiment is self devised. Samples in sealed vessels melted naturally in house. Data were gotten by pretested DDS 11A and pHS 3B.From January to September 1998, 104 samples were tested, among which 19 samples' pH<5.6, the percentage was 18.3%. So the conclusion can be made that acid rain appeared in Antarctica. On the bases of environment background value and wind direction when acid rain appeared,following can be possible reasons for appearance of acid rain. Pollution of other place was brought to Antarctica by circulation of atmosphere,acid rain formed when it rains.
