AIR quality maps will show exactly how fresh the air is where you live.
Cheshire West and Chester Council has begun publishing its work to monitor air quality on new web pages.
Residents can find out what the air is like where they live or work with a postcode.
A series of links within the maps go to current air pollution levels, monitoring graphs, historical data and permitted processes regulated by the council.
The provision of real-time data on graphs – updating every 15 minutes – means visitors can also search by location or pollutant.
The interactive maps can be used to obtain information about current air pollution levels from sophisticated real-time monitoring stations, historical readings from more than 80 diffusion tube sites and the industrial processes regulated by the council.
