Abstract
This research seeks to better define particle inhalability, the fraction of ambient particles that are inhaled as a function of particle size, breathing conditions, and ambient air velocity and direction. Inhalation of large particles (10-1 SO micrometers) such as heavy metals, pesticides, radioactive materials, pharmaceuticals, wood dust, or corrosive materials have a local or systemic toxicity that poses a health risk regardless of where in the respiratory tract they deposit. More complete information of inhalability is needed to correctly assess the health risks of exposure to such particles.
