Human Studies Facility

Chapel Hill, North Carolina

Human Studies Facility: The Concentrated Air Particle System (CAPS) concentrates outside air ambient particles by a factor of six to eight. Particles range in size from 0.1 to 2.5 microns. Ozone and nitrogen dioxide are available as additives.

The Human Studies Facility, located on the campus of the University of North Carolina at Chapel Hill, offers scientists the ability to study the health effects of airborne pollutants using state-of-the-art exposure chambers. The chambers can deliver most gaseous pollutants at precise concentrations and atmospheric conditions, and their instrumentation permits the measurement of pollutant-induced changes in lung function and heart-rate variability. The facility contains five Rochester-style chambers, four sound-proof rooms, and four in vitro exposure systems. Existing pollutant-delivery capabilities include ozone, sulfur dioxide, nitrogen dioxide, and volatile organic compounds.
