Detection of alkaline ultrafine atmospheric particles at Bakersfield, California
Article Abstract:
The general consensus of previous studies on the health effects of particulate air pollution is that it is a major risk factor for increased cardio-pulmonary disease and mortality. The following study conducted between January 14 and 23, 1999 at Bakersfield, California utilized a filter-based sampler and two collocated micro-orifice uniform deposit impactors to measure both the chemical composition and size distribution of atmospheric particulate matter. Results suggested that deep areas of the human lung that collect ultrafine particles could be exposed to alkaline or locally acidic conditions, even if the integrated airborne particle complex is almost neutral.

Evaluation of media and derivatization chemistry for six aldehydes in a passive sampler
Article Abstract:
Ambient exposures to Aldehydes, which result from both automotive sources, natural, and industrial processes, are expected to increase due to the use of alternative fuels and additives derived from ethanol and methanol. The following study examined a GMD passive sampler for its suitability in measuring over a 7-day period 6 different aldehydes in population exposure studies. Results from the study are discussed.
