Although much attention has been paid to investigating and controlling air pollution in China, the trends of air-pollutant concentrations on a national scale have remained unclear. Here, we quantitatively investigated variation pollutants China using long-term comprehensive data sets from 2013 2017, during which Chinese government made major efforts reduce anthropogenic emission polluted regions. Our results show significant decreasing trend PM2.5 concentration heavily regions eastern with...
Abstract. Hydroxyl (OH) radicals, nitrate (NO3) radicals and ozone (O3) play central roles in the troposphere because they control lifetimes of many trace gases that result from anthropogenic biogenic origins. To estimate air chemistry, atmospheric reactivity oxidation capacity were comprehensively analyzed based on a parameterization method at suburban site Xianghe North China Plain 6 July 2018 to August 2018. The total OH, NO3 O3 reactivities varied 9.2 69.6, 0.7 27.5 3.3×10-4 1.8×10-2 s−1...
Single particle aerosol mass spectrometers (SPAMS) have created significant interest among atmospheric scientists by virtue of their ability to provide real-time size-resolved information on the chemical composition aerosols. The objective this study is evaluate newly developed single analysis technique in terms characterization and source apportionment ambient aerosols comparing it with traditional filter-based methods. In study, an air quality monitoring campaign was conducted over a...
