Evaluate and Characterize Mechanisms Controlling Transport, Fate, and Effects of Army Smokes in the Aerosol Wind Tunnel
Abstract
An evaluation of the terrestrial transport, transformations and ecological effects of phosphorus red phosphorus-butyl rubber (RP/BR) smoke obscurant was performed at Pacific Northwest Laboratory. A similar evaluation using white phosphorus (WP) smoke/obscurant is currently proceeding. Future testing with other smokes are planned. The objective of this research program is to characterize the effects of smokes and obscurants on: (1) natural vegetation characteristic of U.S. Army training sites in United States; (2) physical and chemical properties of representative of soils of those sites; and (3)soil microbiological communities. The influence and interactions of smoke/obscurant concentration, relative humidity (25%, 60%, 90% and simulated rain) and wind speed of 0.22 to 4.45 m/s by smoke is assessed. Five plant species and four soils were exposed to both single and repeated doses of RP/BR smokes in the Pacific Northwest Laboratory P-3 rated recirculating environmental wind tunnel. Detailed results for RP/BR and limited results for WP are presented. Keywords: Environmental fate, Persistence, Vegetation surface, soil surface, Environmental effect plants, Earthworms, Soil microbial.
