Abstract:

Number concentrations of large and giant atmospheric particles and particles containing sulfate and water-soluble constituents were determined. Particles were collected by means of an Andersen multistage impactor and examined by means of an optical microscope. The number of particles collected and concentration of sulfate and water-soluble particles at the isolated New Mexico sampling site were comparable to literature-cited values of average continental concentrations over mountains or unpolluted areas. The number concentrations of giant and large particles did not appear to be influenced in the same way by meteorological parameters. Increases in the number of large particles were mirrored by corresponding increases in sulfate content. Data for relating Andersen sampler aerosol number concentrations to concentrations reflected by the Royco 202 light scattering aerosol counter are given.
