Abstract This study investigated size segregated mass concentrations and emission rates of particulate matter (PM), organic carbon (OC), elemental carbon (EC) as well as elemental composition generated during heating corn oil. Also, the impact of table salt on PM emissions from heated corn oil was investigated. Experiments were conducted using an electric stove in an on-campus house at Middle East Technical University Northern Cyprus Campus during January 2015. Fine mode particles were collected in this study. A statistically significant reduction of 56% (P<0.05) in total particle mass concentration was observed when salt was added to the heated oil compared to the heated pure corn oil. The size segregated average mass emission rate and emission flux values of OC emitted during heating pure corn oil showed a peak at 0.65-1.1 µm. Total OC emission rate and flux values were 5.83×101 mg.min-1 and 1.96×103 mg.min-1.m-2, respectively. A uimodal OC size distribution was observed when salt was added to the oil resulted in total OC emission rate and flux to be 2.35×101 mg.min-1 and 7.58×102 mg.min-1.m-2, respectively. The total EC emission fluxes for heated pure oil and pure oil with salt were measured to be 6.07×101 and 2.26×101 mg.m-2.min-1, respectively. The three most abundant heavy metals emitted during heating pure corn oil and corn oil with salt were Fe, Ti, Sr and Fe, Ti, Zn, respectively. The total metal concentrations decreased from 6.04 to 4.01 mg.m-3 in the presence of salt compared to the pure oil.
