 | This exploratory study performs preliminary ground work towards identifying adducts formed between DNA and metabolically activated trinitrotoluene (TNT) intermediates for potential assessment of their applicability as biomarkers of environmental contamination. Chromatographic comparisons between control and TNT-adducted hydrolysates allowed the tentative identification of two TNT-adducted nucleotides. Chromatographic profiles of TNT- adducted DNA hydrolysates featured these compounds eluting in the 21.4- to 22.6- min retention window. The suspect adducts were not observed ... |

| The goals of this effort were to confirm and expand data related to the behavior and impacts of munitions residues upon human food chain components. Plant species employed included corn (Zea mays), alfalfa (Medicago sativa), spinach (Spinacea o!eraceae), and carrot (Daucus carota). Plants were grown from seed to maturity (70 to 120 days) in a low-fertility soil (Burbank) amended with either 14C-TNT or 14 C-RDX at which time they were ... |

| The objective of the present studies was to elucidate the environmental behavior and fate of 2,4,6trinitrophenylmethylnitramine (tetryl) in the soil/plant system in three different types of soils incubated for 60 days, no tetryl was detectable after 11 days, most of the radiolabel was associated with non-extractable soil components (43 to 58%), and tour transformation products appeared rapidly, of which two were identified as N- methyl-2,4,6trinitroaniline and N-methyl-aminodinitroaniline isomer. Short-term hydroponic ... |

| The primary objective of this study was to characterize the fate and response of soil and biotic components of the terrestrial environment to aerosols, deposited brass, and brass in combination with fog oil. Important physical, chemical, and biotic aspects were investigated using an environmental wind tunnel. Air/surface deposition rates were determined for foliar and soil surfaces, both in the absence and presence of fog |

| The object of the present investigation was to elucidate the environmental behavior and fate of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) , particularly as related to its transport and chemical form in the food chain. To meet This goal, we needed to adapt and develop suitable analytical methodology to fractionate and characterize both RDX and RDX-derived residues in soil and plant matrices. Using the methodology that we developed, we assessed the chemical and physical ... |

| This report assesses the environmental fate and effects of mixed obscurant smokes comprised 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 ... |

 | The terrestrial transport, chemical fate, and ecological effects of hexachloroethane (HC) smoke were evaluated under controlled wind tunnel conditions. Primary objectives of this research are to characterize and assess the impacts of smoke and obscurants on: 1) natural vegetation characteristic of U.S. Army training sites in the U. |

| The objective of these investigations was to elucidate the environmental behavior and fate of trinitrotoluene (TNT). Emphasis was placed on those chemical transformations occuring in soils and in plant tissues following uptake and on the probable impact of these chemical transformations on the food chain. Analytical methodology was developed to fractionate and characterize both TNT and TNT-derived residues in soil and plant matrices. The procedures developed in this program extend ... |

| This report provides detailed information regarding a series of laboratory environmental fate and effects tests that were performed with the chemical agent simulant, 2-chloro-ethyl ethyl sulfide (CEES). Aerosols of CEES were generated within a Henderson chamber to allow exposure of plants, soils, and soil microbial communities. Additionally, aerosols were generated for exposure of freshwater aquatic organisms. Aerosols were characterized for mass concentration and particle size with chemical content of the ... |

| This report provides detailed information regarding a series of laboratory environmental fate and effects tests that were performed on two chemical agent simulants. Simulants are compounds whose properties closely approximate those of actual agents so they may be used in training and materiel development. The two simulants selected for testing, diisopropyl fluorophospate (DFP) and diisopropyl methylphosphonate (DIMP), have divergent physical and chemical properties as well as concentration at which they ... |
