Researchers launch innovative air pollution forecasting software


Researchers at the University of Essex will launch a software package this week designed to predict the exposure to pollution suffered by people in indoor urban environments.

The package, called the Urban Exposure Module, is a state-of-the-art, user-friendly management decision software tool aimed at helping administrators quantify and deal with the health risks associated with pollution in urban environments. Its use could help in the understanding and possibly prevention of major health problems that are caused by airborne pollutants.

The Urban Exposure Module provides local, regional and national governments with a system to translate measured outdoor pollution concentrations or emissions into real health risks for people in domestic environments and will enable more effective air pollution control strategies to be developed and administered. It is the culmination of a collaborative three year European Union funded project which has seen the Essex team work with partners across Europe. The new software has already been unveiled in Oslo and Prague and will be launched in the UK at a London workshop on Wednesday 29 June.

Professor Ian Colbeck, leader of the Essex team based in the University’s Department of Biological Sciences, explained: ’Current regulation and legislation relating to air quality is based on measurements made outdoors. However, most people spend 80 per cent of their time indoors and for some groups, such as the elderly and mothers with pre-school age children, this statistic is even higher. Therefore, it is really rather important that we understand the risks when indoors.

’In order to develop the system, we made extensive simultaneous measurements of the indoor and outdoor concentrations of a range of pollutants in a variety of buildings in five major European cities. We were then able to establish a set of models of likely indoor concentrations based upon the outdoor readings. From our estimated indoor concentrations we could then estimate the amount that a person would inhale. The software can then be used to forecast exposure levels or can be used as a diagnostic tool to investigate pollution incidents.’

The project also took into account water-borne pollutants and how, and in what doses, they might enter the body.

The team’s results were used to develop the new software which is designed to work best when integrated into an Air Quality Management System that uses geographical information to track and monitor outdoor air quality.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
