Do wood burners add to air pollution in cities? Yes, say citizen scientists

Pioneering Bristol study blames the solid-fuel burners in people's homes for breaches of World Health Organisation guidelines

Like many parts of the country, Bristol has experienced a huge rise in the number of houses installing wood burners over the past decade. But as they have proliferated, mainly in the wealthier parts of the city where many Victorian and Georgian houses have been renovated, so too have fears that they cause pollution.

And now a group of citizen scientists taking part in the first community-led project targeting toxic smoke from wood burners has discovered new evidence about their dangers.
