利用南京空气自动监测数据及 PM2.5组分监测结果,分析了2011年夏收秸秆焚烧期间大气污染特征,并探寻快速判别秸秆焚烧影响的指标及方法。结果表明:秸秆焚烧期间 PM2.5污染特征显著,其组分中 K +、EC、OC 等浓度相对偏高。基于离子组分及碳元素在线监测数据,可选取 K +作为快速判别指标,并根据 K +与 PM2.5的相关性,计算秸秆焚烧对PM2.5的贡献。同时结合 OC、EC 浓度变化,综合判别秸秆焚烧对空气质量的影响程度。
利用南京空氣自動鑑測數據及 PM2.5組分鑑測結果,分析瞭2011年夏收秸稈焚燒期間大氣汙染特徵,併探尋快速判彆秸稈焚燒影響的指標及方法。結果錶明:秸稈焚燒期間 PM2.5汙染特徵顯著,其組分中 K +、EC、OC 等濃度相對偏高。基于離子組分及碳元素在線鑑測數據,可選取 K +作為快速判彆指標,併根據 K +與 PM2.5的相關性,計算秸稈焚燒對PM2.5的貢獻。同時結閤 OC、EC 濃度變化,綜閤判彆秸稈焚燒對空氣質量的影響程度。

The study analysed the characterization of air pollution during summer straw burning in Nanjing in 201 1 based on the data of air quality automatic monitoring and the component of PM2.5 ,and discussed the rap-id identification indicator and method of air pollution caused by straw burning.The results indicated that air pol-lution was characterized by fine particles with an abnormal high level of water soluble potassium (K +)and ele-mental carbon (EC)and organic carbon (OC).By using aerosol water soluble ions and carbon online monito-ring technology,the variation of K +and OC and EC concentrations and the comparison of PM2.5 from straw burn-ing and PM2.5 in air can be taken as the rapid identification indicator and method of air pollution caused by straw burning.
