Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to survey the current status of field sampling and on-site analytical methods for detecting and quantifying secondary explosives compounds in soils (Table 1). The paper also includes a brief discussion of EPA Method 8330 (EPA 1995), the reference analytical method for the determination of 14 explosives and co-contaminants in soil. This report is divided into the following major sections: introduction; background; an overview of sampling and analysis for explosives in soil; data quality objectives; unique sampling design considerations for explosives; procedures for statistically comparing on-site and reference analytical methods; a summary of on-site analytical methods; and a summary of the current EPA reference analytical method, Method 8330 (EPA 1995). Although some sections may be used independently, joint use of the field sampling and on-site analytical methods sections is recommended to develop a sampling and analytical approach that achieves project objectives.

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.

This book was released on 2001 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: On-site determination of nitroaromatic, nitramine, and nitrate ester explosives compounds in soils was performed using a field-portable gas chromatograph (GC)equipped with a thermionic ionization detector (TID)selective for compounds with nitro functional groups. Soil samples were extracted with acetone. A 1 microliter volume of the filtered soil extract was manually injected into the GC, allowing for the rapid qualification and quantification of the suite of explosives that often coexist in soils at military training facilities and other defense-related sites. Good agreement was established for the concentrations of several explosives analytes when this method of analysis was compared to either high-performance liquid chromatography (Method 8330)or GC electron capture (Method 8095)analysis. Comparisons were performed for sample extracts and for soil subsample replicates distributed for on-site preparation and analysis during a field verification test performed under the auspices of the U.S. Environmental Protection Agency's Environmental Technology Verification (ETV)Program.

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The on-site implementation of a sampling and analysis plan for the determination of explosives residues exposed a large uncertainty in our ability to quickly obtain representative subsamples from either large (>500 g) composite and/or large discrete samples. To improve the representativeness of on-site analysis, a simple on-site processing (grinding and mixing) and subsampling protocol was evaluated. Surface samples from three firing range characterization activities were taken through a procedure where the bulk samples were air-dried, sieved (#10, 2 mm), ground with a portable hand-operated mill, mixed, and then subsamples using layered bedding technique. This approach reduces laboratory-subsampling variance for both sparsely vegetated and vegetated surface soils. Moreover, during a subsequent dynamic sampling and analysis effort, this protocol was success fill in ranking explosives residue concentrations associated with a specific military training activity.

This book was released on 2006 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current methods for the analysis of explosives in soils utilize time consuming sample preparation workups and extractions. The method detection limits for EPA Method 8330 for most analytes is substantially higher than the typical explosive concentrations encountered in soils near unexploded ordnance items, landmines, or other hidden explosive devices. It is desirable to develop new analytical techniques to analyze soil with low concentrations of explosives to support the development of explosive sensors. This report describes efforts to adapt headspace solid phase extraction and gas chromatography/mass spectrometry to provide a convenient and sensitive analysis method for explosives in soil.

Book excerpt: The Analysis of Explosives surveys the principles of the various analytical methods, describes how these methods are used for the analysis of explosives, and reviews the major analytical work carried out in this field. Organized into 15 chapters, this book begins with the classification of explosives. Subsequent chapters discuss the different methods for the analysis of explosives. The detection and identification of explosive residues and hidden explosives are also explained. This monograph will be useful as a reference book for chemists in analytical and forensic laboratories, as well as a textbook for graduate students in analytical chemistry and forensic sciences.
