摘要
通过实验建立了西安城区大气PM_(10)中SO42-、NO3-质量浓度的数据及其与PM_(10)的相关度。结果表明,空气污染状况下,小于PM2.1的细粒径颗粒物是PM_(10)的主要组成部分,西安市城区燃煤发电、冬季燃煤取暖、生活用煤导致SO42-的分布及排放相对稳定,汽车尾气的排放和其他因素影响导致NO3-在不同时间段的分布变化较大。
In this paper,the mass concentration data of SO4^2-,NO3^-in PM 10 and their correlation with PM10 in Xi'an urban area were established through experiments.The results show that the fine particle size less than PM2.1 is the main component of PM10 under air pollution.The distribution and emission of SO4^2-are relatively stable due to coal-fired power generation,coal-fired heating in winter and domestic coal in Xi'an city.The distribution of NO3^-is relatively stable due to the emission of automobile exhaust and other factors.
