【摘要】全球气候变化和环境问题是当代人们共同关注的热点。两极地区在地理上具有特殊性 ,其大气和冰芯的微粒记录包含了火山 ,沙尘暴以及人类活动等特殊事件的信息。本文在总结前人研究的基础上 ,重点讨论了硫化物、碳黑、氮氧化物及硝酸盐、有机污染物以及重金属等大气中与人类活动密切相关的微粒物质

【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.
