| 摘 要： | 2001年春季在青岛采集了3次沙尘暴过境时的大气气溶胶粒子，并利用单个气溶胶粒子分析方法对沙尘粒子含有硫酸盐和硝酸盐的状况进行了分析研究。结果发现3％～13％的沙尘粒子含有硫酸盐，6％～10％的沙尘粒子含有硝酸盐。这些比例远小于无沙尘时北京、青岛等城市污染大气中矿物粒子所含这些成分的比例，表明沙尘粒子在从内陆源区传输到沿海地区的过程中对大气中硫酸盐和硝酸盐生成的促进作用远不如城市污染大气中的矿物粒子明显。 |

| Abstract: | Atmospheric aerosol particles were collected in Qingdao during three dust storm periods in the spring of 2001, and the sulfate and nitrate contained in dust particles were detected by using individual aerosol particle analysis method. It is shown from the analysis results that 3% to 13% of dust particles contained sulfate and 6% to 10% of dust particles contained nitrate. The above ratios are much smaller than those observed in the polluted urban atmosphere in Beijing and Qingdao, which indicates that the promotion of particulate sulfate and nitrate formation by dust particles during their transport from inland source area to coastal area might be much weaker than that by mineral particles in the polluted urban atmosphere. |
| Keywords: | dust particle Qingdao sulfate nitrate |
