Benzene:Toluene ratios were being calculated to further estimate the smoke affect (Desk 4). Benzene/Toluene ratios need to rise in smoke as compared to vehicular emissions. The traditional ratio for vehicular emissions may be lower than 0.5 (Kerchich and Kabachi, 2012), and we see ratios a bit increased. While there was minimal wildfire smoke encountered at the bottom internet sites, this knowledge set can be utilized as track record ranges in danger calculations or for comparative to knowledge from other a long time.
