摘要
采用PAN在线分析仪对唐山市2023年8月1日—2023年9月30日的大气光化学污染状况进行观测,分析PAN浓度特征及其主要污染物的关系。结果显示:观测期间PAN日均体积分数为0.297×10^(-9)~7.650×10^(-9),典型天气PAN体积分数受温度影响比较显著;唐山夏季PAN体积分数与北京、合肥、杭州、深圳等地观测结果处于同一水平,但相对较高;PAN与J(NO_(2))日变化趋势比较接近,略有区别;PAN与NO_(2)变化趋势存在一定的相关性,呈现较弱的线性关系;PAN与O_(3)体积分数变化规律相似,在夏季呈现比较类似的变化趋势。
A PAN on-line analyzer was used to observe the PAN in Tangshan from 1st August 2023 to 30th September 2023 and the characteristics of the PAN concentration and its relationship with the main pollutants were analyzed.The results show that the average daily volume fraction of PAN during the observation period ranged from 0.297×10^(-9) to 7.650×10^(-9) and the volume fraction of PAN in typical weather was significantly affected by the temperature the volume fraction of PAN in Tangshan in summer was at the same level of volume fraction as that of the observation results in Beijing Hefei Hangzhou and Shenzhen but it was relatively higher the daily trend of PAN and J NO_(2) was close to each other and slightly different there is the certain correlation be-tween the change trend of PAN and NO_(2) and it presented a weaker linear relation the change trend of PAN and O_(3) volume fraction changes in the law of change is similar and in summer it showed a relatively similar law of change.
