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.
