Atmospheric pollution from vehicle emissions : measurements at four sites in Coventry, 1973.

Continuous measurements of the atmospheric concentrations of CO, Hydrocarbons, oxides of nitrogen and particulate lead were made at four sites in Coventry in 1973. The pollution at these sites was shown to arise mainly from the traffic, and was at levels comparable with those reported elsewhere. A mathematical model relating pollution levels to wind speed and traffic flow was developed.
