Abstract:
An evaluation of the terrestrial transport, transformations and ecological effects of phosphorus red phosphorus-butyl rubber RPBR smoke obscurant was performed at Pacific Northwest Laboratory. A similar evaluation using white phosphorus WP smokeobscurant 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 3soil microbiological communities. The influence and interactions of smokeobscurant concentration, relative humidity 25, 60, 90 and simulated rain and wind speed of 0.22 to 4.45 ms by smoke is assessed. Five plant species and four soils were exposed to both single and repeated doses of RPBR smokes in the Pacific Northwest Laboratory P-3 rated recirculating environmental wind tunnel. Detailed results for RPBR and limited results for WP are presented. Keywords Environmental fate, Persistence, Vegetation surface, soil surface, Environmental effect plants, Earthworms, Soil microbial.
