Book Site Characterization for Explosives Contamination at a Military Firing Range Impact Area

Download or read book Site Characterization for Explosives Contamination at a Military Firing Range Impact Area written by Thomas F. Jenkins and published by . This book was released on 1998 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted at the inland firing ranges at Fort Ord to determine the current levels of explosives residues and to recommend appropriate future site characterization techniques. A set of 280 soil samples was collected from depths ranging from 0-15 cm to 105-120 cm from anti-tank ranges 44 and 48. Sampling locations were selected on the basis of the locations of current and former targets, and included an area away from specific targets and a background area, not affected by local detonations. HMX was the explosives residue present at the highest concentration. Much lower concentrations of RDX, TNT, and two isomers of aminodinitrotoluene were also detected. Explosives residues were largely confined to surface soils near tank targets. A major problem for site characterization was found to be the large spatial heterogeneity present. Composite samples very effectively provided representative samples for 5- x 5-m size grids. A colorimetric on-site method gave reliable results for HMX, relative to SW846 Method 8330. No currently available on-site method for RDX was found to be adequate in the presence of much higher concentrations of HMX.

Book Ecotoxicology of Explosives

Download or read book Ecotoxicology of Explosives written by Geoffrey I. Sunahara and published by CRC Press. This book was released on 2009-06-01 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Managing sites contaminated with munitions constituents is an international challenge. Although the choice of approach and the use of Ecological Risk Assessment (ERA) tools may vary from country to country, the assurance of quality and the direction of ecotoxicological research are universally recognized as shared concerns. Drawing on a multidiscip

Book Trace Chemical Sensing of Explosives

Download or read book Trace Chemical Sensing of Explosives written by Ronald L. Woodfin and published by John Wiley & Sons. This book was released on 2006-12-15 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely book covers the most recent developments in the chemical detection of explosives in a variety of environments. Beginning with a broad view of the need for and the potential applications of chemical sensing, the book considers the issue of how to effectively include chemical sensing into systems designed to find hidden explosives devices. Offering a firsthand look at the latest technologies direct from those who are actively developing them, the book features: A look at the history of the field, including the contributions of recent programs A brief explanation of the chemistry of various explosives and differences in the place where they may be detected An introduction to the problems presented by trace element sensing An overview and comparison of the technologies currently being used and developed Case studies of field experiences with chemical sensors A look at the emerging threat of non-traditional explosives This book is an important reference for explosives engineers, systems engineers involved in the development of related devices, government agencies and NGOs involved in demining efforts, military and law enforcement specialists in mines and explosive ordinance disposal (EOD), as well as environmental scientists and chemists involved in explosives research. In addition to providing field workers with knowledge that will help them decide where and how to search for explosives using chemical sensors. It will provide them with an understanding of the potential and the limitations of chemical sensing in their search for and identification of dangerous devices.

Book Stability of CL 20 TNAZ HMX RDX NG and PETN in Moist Unsaturated Soil

Download or read book Stability of CL 20 TNAZ HMX RDX NG and PETN in Moist Unsaturated Soil written by Thomas F. Jenkins and published by . This book was released on 2003 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stability of a number of the chemical components of energetic materials was evaluated in three moist, unsaturated soils. This study was conducted to evaluate the stability of several components of currently used energetic materials and two chemicals that may be used in future energetic material compositions in unsaturated, moist surface soils from three military training ranges. The compounds studied were nitroglycerin (NG), pentaerythritol tetranitrate (PETN), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7- tetrazocine (HMX), hexanitrohexaazaisowurtzitane (CL-20), and 1,3,3-trinitroazetidine (TNAZ). Three soils from military training ranges were fortified using an aqueous spiking solution and the residual concentrations were measured after 0, 1, 4, 8, 14, and 29 days at 228C in the dark. The results indicate that the half-life of TNAZ and NG in all three test soils was less than one day, the half-life for PETN varied from 0.45 to 2.4 days, the half-life for RDX ranged from 94 to 154 days, the half-life for HMX varied from 133 to 2,310 days, and the halflife for CL-20 varied from 144 to 686 days.
