Air Quality Control
Not the emissions themselves but rather those pollutant concentrations settling in the ambient air after their dispersal (transmission) thus determining air quality are significant for the assessment of possible effects of vehicular exhaust gas emissions on the environment, refer to Chap.1 and 5. If these pollutant concentrations cannot be measured directly, they can be determined mathematically with the help of dispersal models on the basis of emission values available. To assess their effects on human health extreme situations such as in street canyons with dense traffic are frequently drawn upon.
