In March 2018, we measured pollution levels on West Hill for two weeks and recorded hourly nitrogen dioxide (NO2) levels as high as 171 micrograms per cubic metre (ugm3).
At 200ugm3 NO2 is a toxic gas. West Hill likely exceeds the NO2 hourly legal limit of 200ugm3 more than 18 times a year but no one is measuring NO2 levels locally, so there is no evidence of any exceedances.
Every day there’s a continuous slow-moving line of HGVs, coaches, lorries, vans, trucks and cars, repeatedly accelerating, braking and idling along the entire length of West Hill. These vehicles emitting carcinogenic fumes are just meters away from a nursery, a hospital, residential estates, a care home for the elderly and a school with over 1,100 children.
As NO2 is not being measured on West Hill, no action is being taken to protect the families and children breathing this toxic air on a daily basis.
There are hundreds of locations across the UK likely to breach EU and UK legal limits for hourly NO2 levels but are not being monitored locally.
We’re fundraising for an AQMesh air monitor to continuously measure NO2 levels on West Hill. Will you help with a small donation towards the cost?
