Eastbourne a surprise name among UK's most polluted towns and cities

• Air pollution: how does it affect you?

It's perhaps no surprise that Port Talbot, home to one of Europe's biggest steelworks with thousands of tonnes of iron ore imported to its docks every year, tops the list of the UK's most polluted towns and cities.

But Eastbourne, home to the women's tennis tournament and located at the end of the South Downs national park, is not an obvious candidate for the top 10 of the worst UK towns and cities for two tiny types of particulate pollution.
