Inside versus Outside: Ion Redistribution in Nitric Acid Reacted Sea Spray Aerosol Particles as Determined by Single Particle Analysis.

Single particle anal. of individual sea spray aerosol particles showed cations (Na+, K+, Mg2+, Ca2+) within individual particles undergo a spatial redistribution following heterogeneous reaction with HNO3, along with development of a more concd. layer of org. matter at the particle surface. These data suggested specific ion and aerosol pH effects play an important role in aerosol particle structure in ways not previously recognized. [on SciFinder(R)]
