Today we review research from London, UK, aimed at monitoring vehicle emissions using a relatively low cost approach that makes use of the spectral discrimination of absorption of UV wavelength by various pollutants to estimate roadside pollution levels. This type of instrument (named “GUSTO”) may be combined in a network to produce pollution maps that show how and where high and low levels are produced during the day- and how these in turn may affect health of vulnerable populations such as at schools.
