对兰州市除夕夜燃放烟花爆竹前后的大气气溶胶和地面洁净水质样品进行同步采集，完成了11种无机水溶性离子、16种金属元素及高氯酸盐的分析。研究显示：除夕夜燃放的烟花爆竹烟尘，使大气气溶胶中的水溶性K＋较非燃放期平均上涨317．8％；SO32-上涨294．0％；Mg2＋上涨125．5％；使气溶胶中的Ba、Cu、Pb、Co浓度出现了异常变化，除夕夜后地面洁净水中的NO2-较初始浓度上升了595．6％，其次是F-（217．3％）、NO3-（153．9％）、SO42-（153．3％）等，说明被燃放烟花爆竹烟尘污染的大气气溶胶和干沉降物，在返回地表时又影响和污染了原本洁净的地面水质。

The samples of atmospheric aerosol and clean water were collected synchronous during and after New Year ’s Eve fireworks in Lanzhou ,analyzed 11 water -soluble inorganic ions ,16 kinds of metal elements and perchlorate .Study shows that ,the water soluble K+ in the atmospheric aerosol coarse particles of the urban rising by 317 .8% than the average of the non -setting off period , SO32- rising 294 .0% ;Mg2+ rising 125 .5% ,and the concentration of Ba ,Cu ,Pb ,Co in aerosols appeared abnormal changes . After New Year’s Eve ,the concentration of NO2 - in the ground clean water increased by 595 .6% than the initial ,followed by F-(217 .3% ) ,NO3 -(153 .9% ) ,SO4 2- (153 .3% ) and so on .The result shows that ground water quality were polluted by the atmospheric aerosol and dry deposition produced from fireworks .
