The Times newspaper ran this recently:-
New figures from the Government have revealed that people in most towns and cities are being exposed to illegal air pollution. A report submitted to the European Commission showed that the EU’s limit for nitrogen dioxide pollution was exceeded in 38 out of 43 areas of the UK last year. The only five areas to comply with the NO2 limit were: Scottish Borders, Highland, Northern Ireland, Preston, and Blackpool.
A big concern in my book and one that will affect the health of huge numbers of people.
