Enviro Technology’s Smogmobile is out in Southampton again, helping measure the amount of NO2 in the air from rush hour traffic.
Even though it’s a wet blustery day, when typically levels would be low, levels of 200 ug per cubic metre upwards were found – which, if they were consistently reached for a period of an hour or so, would breach the UK guidelines values for NO2. ET’s Air Quality expert, Duncan Mounsor, explains how people living in more congested areas are more at risk.
