Low-cost pollution detectors to tackle air quality (w/video) Rush hour can be maddening. Roads congested with traffic,
Air pollution is the world largest single environmental health risk, causing one in every eight deaths according to figures released last year by the World health organization.
however, industry, domestic heating, power generation and burning are all contributors to pollution. And although the effects of pollution might be noticeable on a particularly smoggy day in a large city,
decades of exposure to only slightly higher levels a level we wouldn even notice can increase the risk of heart and lung diseases,
With this in mind, Jonesteam, together with industrial partners and other universities, has been developing low-cost pollution detectors that are small enough to fit in your pocket,
The electrochemical devices the team developed can measure a wide range of pollutants, including carbon monoxide, nitrogen dioxide and ozone,

Fifty static devices were deployed also around London Heathrow Airport to record 22 months in the life of one of the busiest airports in the world. his was the first time technology like this had been tested in real-world situations as a high-density network,

Jones and colleagues had to develop new smart software methods capable of separating local pollution events from background signals (pollution transported from long range)
The team has been working with Cambridge Environmental Research Consultants developers of world-leading air quality modelling software combining the unprecedented level of data created by the pollution-monitoring studies with model output to enhance the understanding
of pollution dispersion. For instance, sensors can be used to ask whether pollution along bus routes is improved by upgrading the exhaust processing on a bus fleet;
whether people living at the top of high-rise buildings experience more or less pollution than people at street level;
and to what extent changing a route to work, even from one side of the road to another, can affect an individual exposure.

#Solar desalination (Nanowerk News) When graduate student Natasha Wright began her Phd program in mechanical engineering, she had no idea how to remove salt from groundwater to make it more palatable,
Wright began designing an electrodialysis desalination system, which uses a difference in electric potential to pull salt out of water.
This type of desalination system has been around since the 1950s, but is used typically only municipally, to justify its costs.
While other companies are already installing desalination systems across India, their designs are intended to be powered grid.
Shes designed a village-scale desalination system that runs on solar power. Since her system is powered by the sun,
Its useful to install a small-scale desalination system where people are so spread out that its more costly to pump in water from a municipal plant,

the desalination process itself pollutes the ocean with high concentration salt brine that kills marine ecosystems
and destroys ocean life along the California coastline. And that's on top of all the Fukushima radiation that's already causing a marine ecosystem collapse in many areas of the coast.

Several molecules in that environment are able to diffuse into the ichip, allowing the bacteria to thrive in a more natural setting than a petri dish.
This would then allow the car to help reduce stress, for example by changing mood lighting, audio settings and climate control.
