This book was released on 1999-09-24 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of smokes and obscurants have been developed and used to screen armed forces from view, signal friendly forces, and mark positions. Smokes are produced by burning or vaporizing particular products. Obscurants are anthropogenic or naturally occurring particles suspended in the air. They block or weaken transmission of particular parts of the electromagnetic spectrum, such as visible and infrared radiation or microwaves. Fog, mist, and dust are examples of natural obscurants. White phosphorus and hexachloroethane smokes are examples of anthropogenic obscurants. The U.S. Army seeks to reduce the likelihood that exposure to smokes and obscurants during training would have adverse health effects on military personnel or civilians. To protect the health of exposed individuals, the Office of the Army Surgeon General requested that the National Research Council (NRC) independently review data on the toxicity of smokes and obscurants and recommend exposure guidance levels for military personnel in training and for the general public residing or working near military-training facilities.

Henderson and published by . This book was released on 1985 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lovelace Inhalation Toxicology Research Institute has been conducting inhalation toxicity studies on the organic dyes used in colored smoke munitions to provide a health hazard assessment for the workers engaged in fabrication of these smoke munitions. This report summarizes the results of a field sampling effort at the United States Army's Pine Bluff Arsenal to measure the size distributions and aerosol concentrations to which workers might be exposed. Aerosol samples were taken in the workplace during routine operation of the colored smoke grenade fabrication facility. During this sampling period, the M18 yellow smoke grenade was being produced. Filter samples were used to determine the concentration of airborne dye-containing material and cascade impactors were used to determine the particle size distributions. Aerosol samples were analyzed for solvent yellow (SY) by reverse-phase, high-pressure liquid chromatography (HPLC). Dye-containing aerosol concentrations ranged from 0.1 to about 1.5 mg/m3 in the general vicinity of some of the workers. Chemical analyses showed that 40 percent of the total airborne particulate matter was SY dye. Impactor samples indicated that 50-70% of the aerosol was of a size that could be inhaled. Thus the range of air concentrations for worker exposures to the SY dye was

Book excerpt: The first edition of this book, Chemical Warfare Agents: Toxicity at Low Levels, was published just prior to the terrorist attacks of September 11, 2001. The second edition titled, Chemical Warfare Agents: Pharmacology, Toxicology, and Therapeutics, included new epidemiological and clinical studies of exposed or potentially exposed populations; new treatment concepts and products; improved organization of the national response apparatus addressing the potential for CWA terrorism; and improved diagnostic tests that enable rapid diagnosis and treatment. Since the second edition, the chemical warfare agent community has worked hard to advance research for protection and treatment and develop/improve response approaches for individuals and definitive care. Consequently, in addition to updating previous chapters, Chemical Warfare Agents: Biomedical and Psychological Effects, Medical Countermeasures, and Emergency Response, Third Edition features several new chapters that address the Syrian War, chemical destruction, the Organisation for the Prohibition of Chemical Weapons, biomarkers for chemical warfare agent exposure, field sensors, aircraft decontamination, lung/human on a chip, chemical warfare response decision making, and other research advancements. Features: Describes the newest medical interventions, and the latest technologies deployed in the field, as well as developments in the international response to CW usage highlighting recent events in the Middle East Discusses the latest in organizational/interagency partitioning in terms of responsibilities for emergency response, not just in the United States but at the international level—whether prevention, mitigation, medical care, reclamation, or medico-legal aspects of such response Contains the most current research from bench-level experts The third edition contains the most up-to-date and comprehensive coverage of the question of chemical warfare agent employment on the battlefield or in terrorism. Edited by workers that have been in the field for 35+ years, it remains faithful to the scientific "constants," while evaluating and crediting the advances by the industry that have made us safer.

Available in PDF, EPUB and Kindle. Book excerpt: The Lovelace Inhalation Toxicology Research Institute has been coduction genetic toxicology studies on organic dyes used in colored smoke munitions. This report summarizes the results of tests to determine the genotoxic potency of the dyes toward both bacteria and mammalian cells in vitro. The tests were conducted to detect mutations in bacteria and mammalian cells and to determine cell killing, alterations in cell cycle kinetics, sister chromatid exchanges, and chromosome aberration induction in mammalian cells. The dyes evaluated in the report include Solvent Red 24, Solvent Red 1, Disperse Red 11 and terephthalic acid. Disperse Red 11 had chemical contamination that seemed to be responsible for some mutagenic activity. Keywords: Disperse Red 11, Solvent Red 24, Solvent Red 1, Genotoxicity, Dyes, Disperse Red 15.

Book excerpt: Smokes dyes are used by military personnel for signalling and marking purposes. Because dissemination of smoke dyes results in deposition on vegetation, soil and surface waters there is a need to determine their potential environmental impact. The present study was designed to provide part of the data necessary for environmental assessment. The project consisted of seven tasks addressing three basic goals: (1) purification and characterization of study compounds, (2) measurement of reaction rates and identification of products for the most probable transformation products as typified by the anilines. Five pathways or processes were identified that were expected to be important for the environmental fate of the smoke dyes: (1) partitioning from water to soil/ sediment and biota, (Tasks 2, 3, and 4), (2) assessment of metal complexation (Task 5), (3) photolysis on soil (Task 6), (4) transformation in anaerobic sediments (Task 7), and (5) transformation of aeromatic amines (Task 8).

Bice and published by . This book was released on 1984 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The USAMBRDL has an interest in the potential inhalation toxicity of yellow dye (SY) and a yellow/green dye mixture (SY/SG) used in colored smoke munitions. Rats were exposed by inhalation to aerosols of SY or SY/SG generated in a respirable particle size range for 6 hr/day, 5 days/week for 4 weeks. Nominal exposure concentrations selected for both dye exposures were 0, 10, 50, and 250 mg/cum. Animals exposed to the highest concentration of SY (230mg/cum) showed only a slight decrease in weight gain (8 percent) and mild respiratory function changes, with no observable histopathological lesions. Exposure to the lower concentrations of SY dye elicited no observed response. Animals exposed to the highest level of SY/SG dye (210 mg/cum) displayed signs of pulmonary inflammation with histopathological evidence of mild Type II pulmonary epithelial cell hyperplasia and proliferation of foamy alveolar macrophages. Some of the animals exposed to the medium concentration of SY/SG dye mixture (49 mg/cum) showed similar signs. Thus, the lowest toxic exposure concentration of SY dye is> or = 230 mg/cum and that of SY/SG dye is> or = 50 mg/cum under the exposure regime used. Originator supplied keywords include: Solvent Yellow; Solvent Green; 2-(2'-quinolyl)-1,3-indandione, 1,4-di-p-toluidinoanthraquinone.

Henderson and published by . This book was released on 1985 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The USAMBRDL has an interest in the potential inhalation toxicity of yellow dye (SY) and a yellow/green dye mixture (SY/SG) used in colored smoke munitions. In the rangefinding studies, no mortalities or life-threatening lesions were observed in rats exposed for as long as 6 hours per day for 5 days to airborne concentrations greater than 1 g/cu m of either SY or SY/SG. The particle size of the aerosols employed was about 5 micrometers MMAD. In the toxico-kinetic studies, rats inhaled pure 14C-SY aerosols or 14 micrometers C-SY aerosols in combination with SG (a 0.6 ratio of yellow to green by weight). SY was rapidly cleared from the respiratory tract (T sub 1/2-approximately 3 hr.). SG, however, was retained for a longer time (T sub 1/2> 22 days). The major pathway for excretion of SY metabolites was the feces, but some metabolites were also excreted in urine. There was no effect of SG on the kinetics of distribution and elimination of SY. The rapid absorption, distribution, and excretion of SY compared to SG may explain, in part, the differences in lowest toxic concentration observed in the Phase III toxicity studies conducted at ITRI (>250 mg/cu m for SY and> or = 50 mg/cu m for SG).
