| Abstract |
An experimental exposure system for health effects research in environmental pollutants that permits the introduction and control of ozone (O3) to an acrylic plastic chamber in which a human subject actively resides is described. Ozone is introduced into the chamber air intake and is controlled by an electro-mechanical feedback system operating from the electrical output of an O3 gas analyzer. A continuous record of O3 concentration, temperature, and dew point is provided by an analog multipoint strip chart recorder. If the chamber O3 levels exceed preset limits, an alarm system automatically stops the O3 flow and switches the chamber exhaust to purge operation. A complete air exchange occurs every 72 seconds. In an emergency, the chamber can be purged in 190 seconds. Chamber temperature and humidity are dependent upon conditioned laboratory air. |
