This is a high pollution reading I took outside Chadwell primary last week at around 1 metre. It makes the case for the council to commission their own readings at Chadwell at child height. Monitors used by Tesco's or above head height and as a consequence have lower readings. Be great if you could share petition and hopefully we can get up to 1000 signatures by the time the application for the Tesco toxic Towers is heard which could be in January.
