equilibrium and the water uptake of soluble aerosol
components in response to temperature and relative
humidity changes. This course will cover the following
fundamentals: the water uptake of different soluble
components of aerosols, including organic compounds;
the precipitation of solid phases and metastable equilibria;
the Phase Rule; Henry’s law; activity coefficients and
deviations from ideal solution behavior; the Kelvin effect;
and the role of surfactants. We will also discuss the
application of thermodynamic principles used to describe
the formation of cloud droplets (via absorption and
adsorption of water vapor), and present semi-empirical
frameworks used for describing the cloud condensation
nuclei (CCN) properties of atmospheric aerosol.

Abstract: Bioaerosols include viruses, bacteria, fungi,
pollen and their products. Biological particles can range
from nanometers to microns in size. Bioaerosols are
produced naturally, as a byproduct of various activities,
or can be released intentionally to harm populations.
Sampling and detection of bioaerosols are important
for environmental and indoor studies, exposure
assessment, manufacturing quality control and protection
of populations from intentionally released agents. The
same physical principles that are applied to collect
