Aerosols Hazards & Exposures

This page provides links to a variety of information regarding the measurement, control, exposure characterization & health effects associated with aerosols in the workplace. The definition of an aerosol, as used here, is a suspension of small particles or droplets in the air, such as dusts, mists, or fumes. These particles may be inhaled or absorbed by the skin, & can sometimes cause adverse heath effects for workers. NIOSH has carried out extensive research to minimize the adverse health effects associated with aerosol exposures. Results of such research are available through the links on this page.

Aerosol Sampling

While looking for ways to improve the collection and analysis of bioaerosols, a NIOSH scientist has developed a brand spanking new design for a cyclone bioaerosol sampler. A cyclone sampler draws air in to a cylindrical chamber where the air flow is rotated. Particles of a sufficiently huge size move toward the walls of the chamber by centrifugal force, where they are collected.
