A new interactive website has shown some of the worst affected areas for air pollution in Bristol and across the UK.
Addresspollution.org allows you to type in your postcode to check the level of air pollution. It also advises whether there are grounds for action to be taken if the levels exceed the legal limits imposed by the World Health Organisation (WHO).
Every address in the UK has been ranked according to its air pollution levels, relative to other addresses in the country. This number, the percentile ranking, makes it easy to compare addresses.
