Trace explosives signatures from World War II unexploded undersea ordnance

Article Abstract:

Laboratory sediment extractions were performed using the solid-phase microextraction (SPME) method in seawater and detection using the Reversal Electron Attachment Detection (READ) technique and, in the case of DNT, a commercial gas chromatograph/mass spectrometer (GC/MS). The conclusions reveal that, after over 50 years in the environment, ordinance that looked physically intact provided good explosives signatures at the parts per billion level, compared with ordinance that had been cracked open during the explosion, which brought no signatures at the 10 parts per trillion sensitivity level.

On-site immunoanalysis of nitrate and nitroaromatic compounds in groundwater

Article Abstract:

This study undertakes the evaluation of miniaturized field-portable immunosensor developed by the Naval Research Laboratory and engineered by Woodinville, Washington-based Research International Inc. for the detection of quantitation of TNT and RDX in groundwater . The test was undertaken a three former military munitions sites.
