Short summary
Formation of SOA from gas-phase emissions of five heated vegetable oils was investigated in a PAM chamber for the first time. The major SOA precursors from heated cooking oils were related to the content of monounsaturated fat and omega-6 fatty acids in cooking oils. The average production rate of SOA was 3 orders of magnitude lower compared with emission rates of PM2.5 from heated cooking oils. In these experiments, SOA was lightly oxidized.
