The air at Whetstone Stray Allotments is safe to breathe, unlike in many streets in Whetstone, according to monitoring carried out by plotholder Andrew Newby as part of investigations by Barnet Green Party.
Andrew’s plot in Field Three was the only one of nine Whetstone locations where average Nitrogen Dioxide levels were below the annual average legal limit of 40 microgrammes per cubic metre. At some local places, notably outside Boots in Whetstone High Road and also opposite Barnet Council’s Barnet House, readings showed NO2 levels more than twice the legal maximum.
“NO2 is harmful in itself and also indicates the likely presence of other pollutants,” Andrew said.
“In my case, I was relieved that at 27 mg per m3, the reading from my allotment was reasonable. However, I was sad to find that even outside my own house, in out-of-the-way Domville Close, N20, the NO2 result was slightly above the limit.”
Andrew monitored nine sites for two weeks with specialist tubes supplied and later analysed by Gradko Environmental.
