Abstract:

Environmental problems and global changes are the hot spots that nowadays people pay attention to. Polar region is special from geographical point of view. The microparticle in polar atmosphere and ice core contains information of volcano, dust storm and human activity, etc. Based on the previous research, this article discussed the sulphide, the nitrate, organic pollution heavy metal and volcanic dust, etc., which tie up to the human activity. The composition of microparticles in the ice core and atmosphere of the two polar regions indicates that despite the remoteness, these two places have been influenced by human activity especially the Arctic region. There are still a lot of difficulties in the research of microparticle and other impurities in the polar region, such as the analysis method, the sampling and the observation, etc. Advanced works are needed to solve these problems.
