摘要

Aerosols are generated and injected into a new specialized wind tunnel that can reproduce a range of environmental conditions.The wind tunnel is part of the Toxic and Hazardous Aerosol Exposure Facility (T/HAEF) located at Pacific Northwest Laboratory on the Department of Energy's Hanford Site in Richland, Washington. The T/HAEF is designed for total containment (P-3 rated) and houses a sealed, negative pressure, recirculating wind tunnel, controlled environment chambers, microcomputer and an analytical support laboratory. The facility offers a unique ability to conduct aerosol research in a dynamic environment simulating natural field conditions. Wind speeds from 0.2 to 30.0 m/s (65 mph), temperatures between 0 and 45 deg C, and relative humidities from 20% to 95% with mist and rainfall simulation are controlled and programmable through the microcomputer system. The T/HAEF enables researchers to evaluate physical and chemical interactions along with biological and environmental fate and effects of both aerosols and gases. Research currently being performed in this facility and presented in this paper evaluates the environmental fate and effects of various smokes used by the US Army throughout the United States to screen both troop and track vehicle movements during training. 6 refs., 3 figs., 2 tabs.
