A report overviewing aerosol concentrations in China, based on data from literature and recent research by the authors. The data shows TSP and PM-10 concentrations frequently exceed the National Ambient Air Quality Standard, with PM-2.5 accounting for 60% of PM-10 mass. The Chemical Mass Balance method was applied in Beijing to identify sources of PM-2.5, including fugitive dust, coal burning, traffic emissions, and secondary aerosol.
Use Cases
- Analyze exceedances of air quality standards based on reported TSP and PM-10 concentration data.
- Model the chemical composition of fine particulate matter based on reported abundances of organic carbon, sulfate, and nitrate.
- Identify primary pollution sources in urban areas based on the Chemical Mass Balance method results described for Beijing.
- Assess the relationship between NOx emissions and fine particle concentrations based on the described summertime nitrate-sulfate comparison.
Strengths
- Includes specific quantitative findings, such as PM-2.5 accounting for 60% of PM-10 mass.
- Identifies major chemical components of PM-2.5, including organic carbon and sulfate.
- Applies a specific source identification method (Chemical Mass Balance) for PM-2.5 in Beijing.
