Levels of nitrogen dioxide on the A472 at Hafodyrynys were recorded as the highest in the UK outside of central London in 2015 and 2016.

The A472 is a heavily traffic main route which carries 21,400 vehicles per day.

Caerphilly Council's Draft Air Quality Action Plan outlines proposals to reduce nitrogen dioxide pollution in the area that include demolishing houses and building a bypass to re-route traffic.

Other proposals include reducing the speed limit and providing alternative transport options.
