Look at this tiny tube: it is one of a number that have been installed locally in order to get an accurate picture of the air quality situation in our neighbourhood.

Thanks to the Wimbledon Park Residents Association for funding them. These ones will remain in situ for around three weeks before they are sent off for analysis.

Thanks too to the volunteers who took the time to install them. Merton Council has an extremely limited network of monitors. There was no monitor located in busy Plough Lane between 2013 and January 2017, for example, after diffusion tubes ‘went missing’ and were not replaced.

Clean Air Merton unveiled horrifying figures recently detailing monstrously poor air quality levels in our area.
