Sampling Submicron T1 Bacteriophage Aerosols

Effect of air ions on submicron t1 bacteriophage aerosols.

The effect of a high concentration of ionized air molecules on sampling T1 phage aerosols of submicron particle size was evaluated by comparing the phage recoveries of all-glass impingers (AGI-4) and type 6 filter papers. Sampler recoveries of all ionized aerosols were less than the recoveries of nonionized control aerosols. These reductions in recovery were greater with positive ions than with...

Kinetics of submicron oleic acid aerosols with ozone

Heterogeneous reactions involving particles and gas-phase species can alter important chemical and microphysical properties of aerosols, complicating modeling efforts to assess their effects on climate and human health. Organic aerosols are usually the most abundant component of fine aerosols (< 2 µm) after sulfates, and it is in this size range that one finds those aerosols responsible for the...

Rapid heterogeneous oxidation of organic coatings on submicron aerosols

Laboratory studies have found that heterogeneous oxidation can affect the composition and loading of atmospheric organic aerosol particles over time scales of several days, but most studies have examined pure organic particles only. In this study, in order to probe the reactivity of organic species confined near the particle surface, the rates and products of the OH-initiated oxidation of pure ...
