珠三角地区大气中HCHO、O3、NO2的监测与分析
Atmospheric HCHO, O , NO Monitoring and Analysis in Pearl River Delta
摘要
利用长程差分吸收光谱技术于2008年10月15日至11月19日对珠三角地区江门市大气中的HCHO、O3、NO2等污染物 进行了实时监测,结合气象数据,分析了江门地区主要污染物HCHO、O3、NO2的日变化特征;同时,对江门 市的主要污染来源进行了分析。对比了HCHO和其他各类污染物浓度数据的相关性分析及变化趋势,结果表明江门 地区的HCHO主要来源于二次污染。利用多元线性回归分析,进一步证明了该结论。
Abstract
The long-path differential optical absorption spectroscopy (DOAS) technique is used for monitoring HCHO, O3 and NO2 in Jiangmen City in the Pearl River Delta from Oct. 15 to Nov. 19, 2008. Combined with meteorological data, the analysis of major pollutants HCHO, O3, NO2 diurnal variation characteristics in Jiangmen City is made. At the same time, the main sources of pollution in Jiangmen City are analyzed. The correlation analysis and trend comparison of HCHO and other types of pollutants concentration data indicate that the source of HCHO in Jiangmen City comes mainly from secondary pollution. Results of multiple linear regression also confirm this conclusion.
