The nearby A96 corridor contributes steady vehicle emissions that affect roadside readings. St Neots sits within Cambridgeshire, and its air quality profile is driven mainly by road traffic and the density of the centre. Thanks to cooler northerly winds, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards.
