被动差分吸收光谱法 北京奥运会 区域污染源 排放通量 passive differential optical absorption spectrosco Beijing Olympic Games area source flux
摘要
利用车载被动差分吸收光谱遥测技术,对奥运期间北京市某大型钢铁厂所在区域内的SO2和NO2排放 通量进行了测量。观测结果表明奥运会赛时该区域SO2和NO2排放通量的平均值分别为4.1 ton/h和1.0 ton/h,并 通过对比表明车载被动DOAS与其它仪器测量结果有较好的一致性。进一步分析后给出了相比6月份两种污染气 体排放通量下降了约44%和78%的结果,说明了减排措施的显著效果。
Abstract
Mobile passive differential optical absorption spectroscopy (DOAS) was used for the remote sensing of the emission flux of SO2 and NO2from area of a steel company during Beijing Olympic Games. The mean values of SO2and NO2flux were 4.1 ton/h and 1.0 ton/h derived from the observation results. The comparison of mobile passive DOAS results with MAX-DOAS observations shows a preferable identity and suggests that the results are reasonable and reliable. A further analysis revealed that the emission flux of these two gaseous pollutants decreased about 44% and 78% respectively. These results indicated that emission reduction had a remarkable effect.
