Changes in the Fluorescence of Biological Particles Exposed to Environmental Conditions in the National Capitol Region

We examined the changes in the fluorescence spectra of bioaerosols when exposed to ambient outdoor conditions for periods of several hours. The bioaerosols in this study were contained in a chamber that allowed sunlight to penetrate, and an inner ePTFE membrane to allow ambient trace gasses to permeate the drums. The bioaerosols were periodically measured with a TSI UV-APS (excited at 355 nm) and a Single Particle Fluorescence Spectrometer (excited at 351 and 263 nm). Data deposited are, UV-APS data files, SPFS data files, solar intensity and environmental trace gas measurments.
