环境空气中铵盐与PM2.5浓度爆发性增长特征研究OACSTPCD
Research on Characteristics of Explosive Growth of Ammonium Salt and PM2 5 Concentration in Ambient Air
基于大气污染防治的严峻性,特别是细颗粒物污染仍是关注的重点,选取四川省乐山市作为研究对象,对2021年频繁出现的PM2.5浓度爆发性增长进行研究.结合主要气态污染物和铵根离子、硫酸根离子、硝酸根离子浓度变化特征分析得出:乐山市的PM2.5浓度爆发性增长与二次无机阳离子(NH4+)、阴离子(SO42-、NO3-)有很好的关联性,Pearson相关系数最大达到0.939、0.954和0.832;同时PM2.5还与SO2、CO等一次污染物呈显著正相关,…查看全部>>
Because of the severity of air pollution control,fine particulate pollution is especially the focus of attention.Leshan,Sichuan was selected as the research object in this paper to study the explosive growth of PM2 5 concentration that occurred frequently in 2021.According to the analysis on characteristics of major gaseous pollutants and concentration changes of ammonium ions,sulfate ions and nitrate ions,it was concluded that:the explosive growth of PM2.5 …查看全部>>
