Impact of Regulations of Traffic Emissions on  PAH Level in the Air

Figure 3.4.3. Influence of chemical age on the inverse relative mutagenicity. The inverse relative mutagenicity is expressed by the ratio between the sum of the PAH reference components, BbjkF, BeP and IP, and the mutagenic activity. The ratio between the relative levels of 2-nitrofluoranthene and 1-nitropyrene is applied as indicator for the chemical age of the polluted air masses. (6 Kb)
