广州亚运会期间多组分污染气体的抽取式FTIR监测

Polluted Multi-Gas Monitoring by Extraction FTIR During Guangzhou Asian Games

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 polluted multigases in the atmosphere were continuously monitored around Guangzhou Baiyun Airport with extraction Fourier transform infrared spectroscopy （FTIR） during Guangzhou Asian Games in 2010. The system structure and spectral quantitative analysis methods were introduced, and concentration results were analyzed. As a result, the cycle of hour average values of carbon monoxide and ozone concentrations had daily periodicity. There were several extreme values during monitoring period, which is still within national secondary standard. The hour average values of ethylene and acetylene concentrations changed synchronously, which should come from the same sources. The monitoring pollutants were not out of limits obviously throughout the Asian Games, during which the emission control measures were effective.
