Volume-based size distribution of accumulation and coarse particles (PM0.1-10) from cooking fume during oil heating

► Particle volume distribution has a close relationship with heating temperature. ► Volume frequency of fume particles is not sensitive to the oil type. ► Volume frequency of PM1-4 accounts for 100% of cooking-generated PM0.1-10. ► Fume particles have a mode diameter 2.7 μm, median diameter 2.6 μm. ► Fume particles have a Sauter mean diameter 3.0 μm, DeBroukere mean diameter 3.2 μm.
