摘　　要：除夕夜至大年初一零时前后,是燃放烟花爆竹最多最集中的时段。作者分别同步采集了2007年春节期间在城区和环境背景点的大气气溶胶粗、细颗粒物样品,并对其中的高氯酸盐进行了比较研究。结果显示,燃放烟花爆竹时产生的高氯酸盐对大气气溶胶产生了非常严重的污染。城区气溶胶粗颗粒中的高氯酸盐较非燃放期平均值(2.154ng/m3)上升1 718.01%;细颗粒中的高氯酸盐较非燃放期平均值(1.640 ng/m3)上升503.04%。在环境背景点气溶胶粗颗粒中的高氯酸盐较非燃放期的平均值(0.653 ng/m3)上升了425.25%;细颗粒中的高氯酸盐较非燃放期平均值(0.317 ng/m3)上升了1 467.82%。It is the most concentrated time around 24：00 between the lunar New Year＇s Eve and New Year＇s Day to set off Fireworks. During this time,the authors collect the samples of the atmospheric aerosol coarse and fine particles of the urban and the environmental background point synchronously. The result shows the perchlorate produced by setting off fireworks makes serious pollution to atmospheric aerosol. The perchlorate in the atmospheric aerosol coarse particles of the urban rising by 1718.01% than the average（2.154 ng/m^3 ） of the nonsetting off period. The perchlorate in the atmospheric aerosol fine particles of the urban rising by 503.04% than the average（1.640 ng/m^3 ） of the nonsetting off period. The perchlomte in the atmospheric aerosol coarse particles of the environmental background point rising by 425.25% than the average（0.653 ng/m3 ） of the nonsetting off period. The perchlorate in the atmospheric aerosol fine particles of the environmental baclqground point rising by 1 467.82 % than the average （0.317 ng/m^3 ） of the nonsetting off period.
