AIR POLLUTION: THE ROLE OF PARTICLES
Air pollution remains a problem in many urban areas. The role of atmospheric aerosols (solid or liquid particles suspended in a gas) in air pollution is considered. There are three fundamental aspects of an air-pollution system: the source of the pollution, the movement and transformation of the pollutant in the atmosphere and the effect of the pollutant on receptors. Particles are classified according to size. In the atmosphere, they experience a variety of physical and chemical processes and changes can occur rapidly. Methods for sampling and analysing aerosols are discussed with reference to filter collection, real-time analysis, mass spectrometry, and laser desorption/ionization. Real-time single-particle mass spectrometry and aerosol time-of-flight mass spectrometry are described. Future directions for the development of techniques for characterizing aerosols are discussed.
