Abstract
Particle light scattering and PM2.5 (particles with aerodynamic diameters less than 2.5 μm) concentration data from air quality studies conducted over the past ten years wereexamined. Fine particle scattering efficiencies were determinedfrom statistical relationships among measured light scattering and fine and coarse mass concentrations. The resulting fine particle scattering efficiencies ranged from 1.7 m2 g-1at Meadview in the Grand Canyon to over 5 m2 g-1 in Mexico City. Most of the derived fine scattering efficiencieswere centered around 2 m2 g-1, which is considerablylower than most values reported from previous studies.
