Now terrorist bomb makers can be located using their human WASTE: Sensors in
sewage tunnels can pinpoint exactly where they are
EMPHASIS system was created by the Swedish Defense Research Agency
Sensors are placed in sewers to detect chemicals used in bomb making
Chemicals are detected either because they have been poured down the
drain or ingested into the terrorist's blood stream and then excreted
Once detected, the information is sent to a command centre
A mobile unit then uses infrared lasers to scan the areas for gas
molecules
These molecules can help further pinpoint the location of a bomb maker

Plans for the next stage in the fight against terrorism could be in the
toilet - quite literally.
Swedish scientists have developed sensors that can be fitted inside waste
tunnels and used to detect bomb making chemicals in sewage.
If suspect chemicals are detected, the sensor alerts the authorities who can
carry out infrared laser 'sweeps' above ground to locate the precise
location of the bomb-making factory.
The Swedish Defence Research Agency (FOI) has developed sensors fitted
inside tunnels, such as the one in this stock image, that can detect bomb
making chemicals in human waste.
The Swedish Defence Research Agency has developed sensors fitted inside
tunnels, such as the one in this stock image, that detect bomb making
chemicals in waste. It uses 'ion-selective electrodes' to determine trace
elements. If the level of ions is high enough to arouse suspicion, the
system alerts the authorities
HOW DOES EMPHASIS WORK?
EMPHASIS is made up of a 'network' of sensors plotted above and underground
that can detect chemicals in liquid waste, and detect gas vapours.
Each sensor contains 'ion-selective electrodes' that sit in the flow of
waste water in sewage tunnels.
If a bomb-maker flushes chemicals down the toilet, or the chemicals and
gases from bomb making are ingested into the person's blood stream and
ultimately enter their urine or faeces, these chemicals will pass through
the sensors.
The ions that are found in these chemicals will travel through the
electrodes and change a resistor's voltage.
This change is recorded and tracked using software designed to seek out even
the smallest traces of suspect ions.
The system is called EMPHASIS, which stands for Explosive Material
Production Hidden Agile Search and Intelligence System.
Developed by the Swedish Defence Research Agency (FOI), it is made up of a
'network' of sensors plotted above and below ground that can detect
chemicals in liquid waste, and detect gas vapours.

Each sensor contains 'ion-selective electrodes' which are around four inches
long and sit in the flow of waste water in sewage tunnels.
If a bomb-maker flushes chemicals down the toilet, or the chemicals from
bomb making are ingested into a person's blood stream and ultimately enter
their urine or faeces, these chemicals will pass through the sensors.
The ions that are found in these chemicals travel through the electrodes and
change the built-in resistor's voltage.
This change is recorded and tracked using software designed to seek out even
the smallest traces of suspect ions.

If the ions are found in 'elevated amounts', data about the type of ions,
the approximate location based on the proximity of the sensors, the time and
the level of ions detected are sent to a command centre.
Mobile units armed with infrared lasers then carry out a scan of the nearby
area in a bid to detect suspect gas molecules and narrow down the target
area.
As the target area is narrowed, extra sensors are placed in the sewers
around that area to pinpoint the precise location.

EMPHASIS is an EU-funded project for the 'detection of production of
explosives.'
The objective of the EMPHASIS project is to test a system for detecting
'ongoing illicit production of explosives and improvised explosive devices
in urban areas.'
According to the FOI website: 'The goal of the EMPHASIS project is to test a
system concept for the surveillance tool of tomorrow for detection and
localisation of illicit bomb factories in urban areas.'
The team have already successfully tested the sensors in waste water inside
a lab and intend to trial the sensors in sewers next year.
