If the sum of odor intensity (SOI) is derived for each sample,they were in the descending order: roasting coffee seeds (6.50), frying cabbage (4.52), brewing coffee (4.14), grilling clam (3.91), boiling clam (3.89), and steaming cabbage (3.21). Their concentration data were also evaluated against regulation guidelines for indoor air quality (IAQ). Comparison of these pollutant data confirms that some cooking approaches can contribute significantly to the build up ofnuisance and hazardous pollution concurrently.
