This study examines the sorption of eight explosives (2,4,6-trinitrotoluene [TNT]; pentaerythritol tetranitrate [PETN]; hexahydro-1,3,5-trinitro-s-triazine [RDX]; diacetone diperoxide [DADP]; triacetone triperoxide [TATP]; ethylene glycol [EGDN], nitroglycerin [NG]; and 2,4-dinitrotoluene [DNT]) to human hair. The study uses only cut hair, which is exposed to explosive vapor. The vapor transfer...
This paper describes the use of headspace solid-phase microextraction (SPME) combined with gas chromatography to identify the signature odors that law enforcement-certified detector dogs alert to when searching for drugs, explosives, and humans. Background information is provided on the many types of detector dog available and specific samples highlighted in this paper are the drugs cocaine and...
CONTEXT Unusual cataracts (flecks) have been reported to occur at very low levels of trinitrotoluene exposure, but prevalence estimates vary widely. Cataracts have not been reported among workers in the United States exposed to organic nitrate explosives. OBJECTIVES To determine the prevalence of unusual cataracts in a population of workers in the United States exposed to organic nitrate expl...
In this study, firstly all methods for increasing of blast temperature and pressure of explosive materials have been investigated, then by introducing the general principles of thermobaric explosives (TBXs), various types of additives used in TBXs are identified and their general properties are presented and analyzed. Furthermore, the limitations arising from the incomplete combustion of alumin...
