Severe Cases of Soil & Water Contamination!
90 million tons of hazardous wastes get dumped into soil and
water each year in EU.
Explosives were found in the groundwater of the
Milan Army Ammunition Plant.
Soil of the Louisiana Army Ammunition Plant found
contaminated with 10000, 1900 & 900 mg/kg of TNT, RDX & HMX, respectively.
The Pantex Plant used during World War II by the U.S. Army is highly
contaminated with explosives.
In the US, the army alone has estimated that over 1.2 million tons of soils
have been contaminated with explosives.

1 gm of soil was weighed into a 2 ml vial.
One ml of acetone was added to the vial and the mixture was shaken vigorously for 3 minutes and then centrifuged.
A known quantity of liquid was then extracted and measured into a
new vial where it was diluted up to 1000:1 with acetone.
One microliter of diluted liquid was then injected into the inlet of the zNose®, maintained at 200°C.

Water was analyzed using Supelco Sep-Pak RDX SPE cartridges.
Each cartridge was conditioned by running 15 ml of acetonitrile followed by 30 ml
reagent grade water through it at 10 ml/minute.
100 ml of the water sample was then drawn through the cartridge at the same rate
using an adjustable valve and a vacuum system to maintain flow.
The cartridge was then flushed with 5 ml of acetonitrile resulting in a 20:1
concentration step.
One microliter of the extract was then injected into the zNose®.
