利用抽取式傅里叶变换红外光谱(FTIR)测量系统于2010广州亚运会期间对广州白云机场地区大气中的多种污染气体进行了连续监测。介绍了系统组成和光谱定量分析方法,并对浓度结果进行了分析。结果显示,一氧化碳和臭氧小时均值浓度具有日周期变化,虽然在监测期间出现了几个极值,但是仍然达到国家二级标准。乙烯和乙炔小时均值浓度具有同步变化规律,两者应来自同一排放源。在整个亚运会期间所监测的污染物组分中未发生明显超标状况,在此期间采取的减排控制措施是有效的。
The use of decimation Fourier transform infrared spectroscopy (FTIR) measurement system during the 2010 Guangzhou Asian Games in Guangzhou Baiyun Airport in the atmosphere of a variety of polluting gases were continuously monitored. The composition of the system and the method of spectral quantification are introduced, and the concentration results are analyzed. The results show that the hourly mean concentrations of carbon monoxide and ozone have a cyclical change of day, and although some extremes occur during the monitoring, they still reach the national second-class standard. The hourly average concentration of ethylene and acetylene has a synchronous variation, and both should come from the same source. No significant overshoot occurred in the contaminant components monitored during the entire Asian Games, and the mitigation control measures taken during this period were valid.
