Sophie Yeo tries out an Atmotube on the streets of Newcastle
Were my daily habits putting my long-term health at risk?
I attach my Atmotube Pro to my bag and set off, on foot, into town.
Device is a small box containing a quietly whirring fan, is connected to phone.
Air is analysed for particulate matter and volatile organic compounds (VOCs).
App provides constant updates on the air quality, including alerts if it drops below a certain level.
I have reached the bus station, and instantly the air exceeds the WHO’s guidelines.
The greatest air pollution problem in Newcastle is not PM2.5 or PM10, but nitrogen dioxide (NO2).
