Title:  Airborne Nanoparticles

Abstract:

Half of the particles in the global atmosphere for when atmospheric oxidation of gaseous precursors leads to the formation of molecular clusters that then grow to become stable particles.  Even when combined emissions of similarly produced particles from combustion and industrial sources, these nanoparticles particles barely register in the measure by which airborne particles are regulated, which is the mass concentration of particles smaller than 2.5 µm diameter – called PM2.5.  Nonetheless, growing evidence suggests that airborne nanoparticles profoundly affect human health and climate, but new approaches to measurement will be needed to make the links quantitative.
