Correctly estimating such cooking emissions in a variety of settings is critical for simulating exposure and informing health guidelines aimed at keeping people safe. Peter DeCarlo Associate professor, environmental health and engineering "With this improved model, we can better understand the potential of exposure to cooking emissions in homes or commercial cooking areas." "We know that cooking emissions move throughout an indoor space, that's why you can smell what someone is cooking from a few rooms away. What we've done with this model is better characterize how thermodynamics changes the composition as those cooking particles as they spread throughout a space," DeCarlo said. "While this detailed model can better characterize potential exposure to cooking-related emissions in indoor spaces, guidelines and public health recommendations remain the same.
