Inhalation and Sampling of Large Particles, 10–150 Micrograms

Details

• Personal Author:

• Description:
  The 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 (10-15 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. Inhalability is sensitive to the direction and velocity of the ambient air motion as well as particle size. This research also seeks to better define the collection characteristics of eight types of personal inhalable samplers as a function of particle size and air velocity. More complete information of inhalability and inhalable particle personal sampler performance is needed to correctly assess the health risks of exposure to large particles and to set occupational standards for such particles.
