'You can feel it in your throat': going to school in a pollution blackspot

Parents at the gates of one London school are not surprised that NO2 levels in the area are well above recommended levels

Copenhagen primary school in north London does not immediately stand out as a pollution hotspot. The school gates open on to a quiet cul-de-sac, while along one side runs the Regent's canal, where birds swoop in the afternoon sunshine. The large Victorian building is topped by an "edible roof garden", designed to allow the children to grow fruit and vegetable in a restful environment.
