Evaluate and Characterize Mechanisms Controlling Transport, Fate, and Effects ofArmy Smokes in the Aerosol Wind Tunnel

摘要

This report assesses the environmental fate and effects of mixed obscurant smokescomprised of White Phosphorus, Fog Oil (FO), and Hexachloroethane (HC) smokes. Overall, based on the environmental fate and effects of the individual obscurant smokes investigated previously significant synergistic effects are indicated in some instances. The chemistry of the FO and HC smokes following deposition to surfaces was generally consistent with their reported individual behavior. However, with WP, the combustion products or rates of conversion of polyphosphates to phosphate appear to be altered by the presence of FO and HC + FO, resulting in elevated levels of non-phosphate P. This may have influenced the higher than expected toxicity of mixed smokes containing WP. Similarly, there may
