摘要
从乌鲁木齐地区大气飘尘及 TSP 的不同功能区、不同季节的差异与变化,得出人为元素 s、pb、Zn、Co、Cr、Ca 等在采暖期分别占其飘尘和 TSP 的11.97%和14.00%,非采暖期分别占6.47%和4.15%,地壳元素 Al、Si、Ca、Mg、Fe 等在采暖期分别占其飘尘和 TSP 的10.97%和13.97%,非采暖期分别占56.63%和52.00%。采暖期以居民燃煤区和工业燃煤区污染较严重,尤其是 S 元素在细粒上的富集率达88%。非采暖期以交通商业区污染较重,科研文化区相对较清洁。
In this paper,the aerosol and particulate content variation are yielded according to the different seasons and different areas of Urumqi The results show that the contents of s,pb,Zn,Co,Cr,Cd emitted from human activities account for 11.97% of aerosol,14.00% of TSP during the period of heating or 6.47% of aerosol,4.15% of TSP during another seasons and the contents of Al,Si,Ca,Mg,Fe etc.emitted from surface of ground account for 10.97% of aerosol,13.97% of TSP during the period of heating or 56.63% of aerosol,52.00% of TSP during another seasons.The air pollution is wors in the coal burng areas during heating period,and espcially there S is about88% of S in the air storing up within the surface of dust.Then the air quality are worse in commercial district and better in cultural district during another season.
