| Abstract: | The concentrations of Pb, CO, CH4 and total hydrocarbons have been measured at a roadside site and at the exit of a multistorey car park. Average concentrations over short periods (10 to 25 min) have been calculated for each pollutant and possible correlations between these average levels of the different pollutants investigated. Significant correlations were found at only one site and the conclusion was drawn that it is only under exceptional conditions that correlations in levels exist over these extremely short averaging periods. |
