Description:
A brief review is given of the "Knowledge" and the "Gaps in Knowledge" of aerosol exposure, physics and chemistry relevant to health effects of aerosols, and presented or discussed in platform or poster presentations at the Symposium on Particulate Air Pollution - Associations with, and Mechanisms for, Human Mortality and Morbidity, January 1994, Irvine, CA. he discussion covers aerosol measurements of various types and their usefulness in estimating aerosol exposure for epidemiological studies, problems in obtaining more precise measures of more specific aerosol related exposure, i.e., fine and coarse mass separately, acidity, or aerosol contributions from specific sources. onsiderations in selecting the best cut point for separating fine from coarse particles and problems in measuring semi-volatile species such as ammonium nitrate, semi-volatile organics, and particle-bound water are examined.
