Map shows Leicester's pollution
Results from a new pollution-scanning device shows how polluted Leicester is. A bird's eye image, taken by researchers from the University of Leicester, shows how pollution levels differ across the city.

Colour maps give dramatic picture of Leicester's air quality - full report
Many of us don't give much thought to the air that we breathe, but scientists from the University of Leicester are doing just that to learn how pollution affects us.
In a world-first experiment they've mapped the whole of the city by plane, to see how fumes and emissions are carried around. They hope the work will mean we can lead cleaner, healthier lives. Chris Halpin reports.
Explanation of world first experiment to map Leicester's air quality
Project leader Dr Roland Leigh, of the Earth Observation Science group, explains to ITV News Central reporter Chris Halpin how the specially adapted Spectrometer mapped air quality around Leicester.
The device gave a reading for Nitrogen Dioxide (NO2) levels between the ground and the plane - which was flying at around 900m.
Each reading corresponds to an area of 6 metres by 100 metres at ground level.

Maps should help to 'understand' sources of pollution
The project leader behind the new pollution maps being used in the city of Leicester said it is the first time in the UK anyone has been able to use airborne technology to map pollution levels. He said:
Pollution maps 'future' of environmental technology
Results from a new pollution-detecting technology, which has been installed in Leicester city, could help with environmental decisions in the future, scientists said.
The technology uses a "heatmap" to show pollution levels in the area, showing levels of nitrogen dioxide (NO2) across the city.
As part of a project "developing solutions to the national problem" of improving overall air quality, scientists have also used a device to map air quality around the city.
Monitoring visible light, it measures how much is lost at specific wavelengths absorbed by nitrogen dioxide.
The device was previously used as part of the CityScan project, to measure pollution in Leicester, Bologna, and London during the Olympics.
Airborne pollution scanner monitors Leicester
Leicester has become the first city in the world to have its air quality mapped out using an airborne pollution-scanner.
This bird's eye image shows how pollution levels vary across the city.
Images were taken by researchers from the University of Leicester from a survey plane flying 900m above the city's roads, parks, industrial estates and houses.
The European Commission is calling on the government to find a solution to improve air quality.
