Both moving run-up areas and using MOGAS can reduce maximum airport Pb impacts. Therefore, it is also logical to consider the combination of the two strategies. This was also modeled for each of the three airports.
Figure 21, Figure 22, and Figure 23 show the three-month average concentrations at RVS, SMO, and PAO, respectively, for the November to January period. The figures represent concentrations when using the best case run-up scenario (Z1 for RVS, Z2 for SMO and PAO). The maximum concentrations from RVS, SMO, and PAO fell from 52, 90, and 121 ng/m3 to 23, 51, and 78 ng/m3, respectively.
