Harrogate headteacher 'concerned' by Cold Bath Road pollution data
Western Primary School installed a pollution sensor in June last year, amid concerns about heavy traffic on Harrogate's Cold Bath Road.
Headteacher Tim Broad was worried about the sheer volume of traffic plus the fact he could tase diesel in his mouth when larger vehicles passed.
Six months on, The Stray Ferret has reviewed the data, which suggests levels of pollutants meet national objectives but exceed guidelines set by the World Health Organisation.
The sensor, which was installed within the school grounds, revealed concentrations of PM2.5, PM10 and nitrogen dioxide (NO2) all fell within the national objectives’ limits for short and long-term exposure.
However, a local pollution campaigner expressed concern that PM2.5 and NO2 levels exceeded WHO guidelines both short- and long-term.
PM2.5 particles are man-made particles suspended in the air, produced by woodburning stoves and transport, as well as industrial processes. When breathed in, these particles can get into the blood and lodge themselves in organs.
NO2 is a gas produced by combustion of fossil fuels. Eighty percent of roadside NO2 pollution is caused by road vehicles. Exposure to the gas can cause inflammation to the airways and exacerbate pre-existing heart and lung conditions.
'No safe threshold for air pollution'
We showed our findings to Western headteacher Tim Broad, who said he was “concerned” by the exceedance of WHO guidelines, Mr Broad added:

Local campaigner Brian McHugh claimed the national objectives were too weak, and children were at risk. He added:
Better monitoring needed
Western Primary School is believed to be the only school in the district with an air pollution sensor, and live measurements from the sensor are available to the public online here.
Mr McHugh called for better monitoring of pollution in and around schools. He said:
In its 2021 Air Quality Annual Status Report, Harrogate Borough Council used 63 monitors throughout the district to measure NO2 levels but had no monitors for PM2.5 particles.
The council itself stated PM2.5 can have a significant impact on health, including “premature mortality, allergic reactions, and cardiovascular diseases”, but it relied on council data from Leeds and York to estimate levels of the pollutant in the district.
