Aerosol particles: suspensions of liquid or solid in vapor
Experiment• Beef and vegetable burgers were both cooked on charcoal/propane grills (figure 1)• Filters picked up total organic emissions from the grills in µg/m3
• They were analyzed in the clean room by a FTIR spectrometer (figure 2)• Charcoal Beef (figure 3), picked up the darkest particles.

Results/ Analysis
• Propane releases less organic emissions than charcoal
• Organic particle concentrations higher when cooking burgers
• Veggies burgers release less particles than beef burgersFigure 2Figure 1

Conclusion/ Implication
• Conclusiono Expectation: Charcoal/Beef mix would give off more organic
materialo Reality: Propane/Beef mix gave off more organic materialo Charcoal/Beef mix had more alkanes overall
• Implicationso Fingerprint of emissions
