Description:
To determine the nature of aerosol particles in a rural area of the eastern United States, aerosol samples were collected at Deep Creek Lake, Maryland, on various substrates and analyzed by a scanning electron microscope (SEM) and a transmission electron microscope (TEM). SEM analysis of particles larger than 2.5 micrometers collected on Nuclepore filters revealed clay minerals, quartz, gypsum, calcite, spores, pollen, plant debris, fly ash, and sulfates. Particles ranging from 0.3 to 2 micrometers were analyzed by TEM for decomposition rate as well as for reaction with the barium chloride and nitron films.
