Investigating the fate of nitroaromatic (TNT) and nitramine (RDX and HMX) explosives in fractured and pristine soils
Received for publication November 6, 2008. Explosives compounds, known toxins, are loaded to soils on military training ranges predominantly during explosives detonation events that likely fracture soil particles. This study was conducted to investigate the fate of explosives compounds in aqueous slurries containing fractured and pristine soil particles. Three soils were crushed with a piston to ...

Measurement of Explosive Residues from Munitions and Armaments by Isocratic HPLC
The government and the military have spent millions of dollars on making millions of tons of explosive materials. Most of these materials are warehoused in storage depots and often-present problems with leaking containers and contamination of the surrounding environment. Some are still used for testing and need to be checked for residual contamination and combustion efficiency. The industrial ...

NFPA 820 Compliance in Wastewater Treatment Plants
Wastewater treatment plants are essential structures in cities and small communities. Such facilities are closely monitored by several professional institutions, such as OSHA and the NFPA. When it comes to the latter group, guidelines set forth in NFPA 820 are regulations that dictate fire hazards in such facilities. Fire related accidents in wastewater treatment facilities are uncommon. However, ...

The evolution of handheld 785 nm Raman spectroscopy: Raman extraction from fluorescence interference
MIRA DS (Metrohm Instant Raman Analyzer) is a handheld Raman system that identifies materials using 785 nm laser excitation. The advantages of using 785 nm Raman are well understood. Excitation with shorter wavelengths produces strong Raman scattering with short acquisition times. This results in a high signal-to-noise ratio and provides excellent spectral resolution with lower power draw. ...

Weak Bonds - the Hidden Power Within Combustible Chemicals
On this anniversary of one of the largest and most devastating industrial incidents ever recorded, we remember the tragedy of Beirut – a blast so immense that it was heard 200 km away in Cyprus. The epicenter of the detonation was at a port warehouse and the fuel was 2,750 tonnes of ammonium nitrate. Ammonium nitrate is one of the most widely used fertilizers, an important constituent of ...

Biological treatment of ammonium perchlorate-contaminated wastewater: a review
Absolute reduction of perchlorate has proven complex owing to the diverse characteristics of the perchlorate ion. Technologies such as chemical reduction, ozone/peroxide, nanofiltration, and reverse osmosis have had limited success, high costs and are not environmentally friendly. A great deal of research and reviews on ion exchange and biodegradation have been carried out, but conditions for ...
