| 摘 要： | 2008年7～8月在北京市奥体中心的遥感所站点连续实时监测碳黑气溶胶(BC),研究其在北京奥运期间的变化特征和来源.奥运会前BC平均质量浓度约为4.58μg/m3,而奥运会期间其平均浓度约为3.07μg/m3,下降比约为33.0%,这说明减排措施有效降低了BC的排放总量.同步监测的可吸入颗粒物(PM10)与BC一致性较好,相关系数为0.86,BC约占PM10的1.9%.比对2007年同期BC浓度数据,也证实了北京地区在实行各项减排措施后,BC的污染情况有较大好转.

| Abstract: | Black carbon aerosol (BC) has been measured at IRSA site in Beijing during July and August, 2008. By analyzing these real-time BC data, the concentration distributions and the sources of BC are concluded. The average concentrations of BC in July and Beijing Olympic Games are 4.58 EQUATION]g/mEQUATION] and 3.07 EQUATION]g/mEQUATION] respectively, that the declining ratio is about 33.0%. It shows that a series of regulations successfully decreased the concentration of BC. The correlation coefficient between daily average concentration of BC and inhalable particles(PMEQUATION]) is 0.86, while the value of BC/PMEQUATION] is 1.9%. Through comparing with the BC concentration of summer in 2007, the results indicated that the concentration of BC has reduced during Beijing Olympic Games. |
