UK city's air so polluted it's like smoking 189 cigarettes a year - see your area

One UK city is so polluted one study has claimed living there is the equivalent to smoking 189 cigarettes a year.

A lot has changed since the Great Smog of London, and Brits are far more aware of the adverse health effects air pollution can have.

But one study has claimed that living in some cities in the UK is akin to passively smoking over 150 cigarettes.
