Abstract Numerous previous studies demonstrated that cooking is one of the major sources of indoor PM. It is important to focus on different cooking components to identify the most influential source which controls the overall cooking PM. This identification may then create opportunities to reduce cooking PM emission. Oil, meat, stove and pan are among the key sources contributing to cooking PM. However, the relative importance of these sources has not been yet investigated under a controlled experimental protocol. It was found in the literature that desorption of semivolatile organic compounds (SVOCs) from the heated metal surfaces including pans and burners contributes to PM formation. Thus, the material coated on the surface of the pans may impact the amount of surface deposited SVOCs, and therefore the PM emission rate. Among different cooking components, the emission rate of PM generated from a heated cooking pan itself has not been yet investigated. The aim of this study is to examine the impact of type of cooking pans including Teflon, cast iron, ceramic and granitium pans on PM emission rates under controlled experimental conditions. Furthermore, this study investigates the relationship between the pan exposure time to indoor air prior to heating and the PM emission rates during the heating. PM1, PM2.5, PM4, PM10 and total particle number emission rates from heated pans are estimated using a DustTrak DRX, TSI and CPC 3007, respectively. A low-cost PM monitor, Dylos, is also implemented to investigate its performance compared to the well reference instruments. While the experiments are being conducted, the primary results showed that the granitium, ceramic, cast iron and Teflon pans produced 2.43×1012, 1.29×1012, 1.92×1013 and 2.42×1013 particles/h, respectively. The longer exposure time to indoor air, the longer required heating time to lower the PM emissions to the background level. More results will be presented during the AAAR 36th annual conference.
