Mean particle size distributions recorded during cooking and candle exposure. Legend: Cooking in blue; (right y-axis) and candle exposures in red (left y-axis). Values show means as calculated from three cooking experiments carried out on 07.05.21, 07.11.19, and 30.10.19 and four candle experiments carried out on 09.05.19, 13.05.19, 21.11.19 and 05.11.19, respectively, using SMPS. See [25] for examples of size distributions from individual experiments. (a) Particle number size distributions in the range 2.4 to 79.1 nm (nano DMA). (b) Particle number size distributions in the range 14.6 to 661.2 nm (long DMA). (c) Particle mass size distributions in range 2.4 to 79.1 nm (nano DMA). (d) Particle mass size distributions in range 14.6 to 661.2 nm (long DMA). The two different SMPS size intervals were measured in sequence. The particle mass size distributions from cooking experiments are plotted assuming two different densities: blue crosses denote results calculated using the density assumed for candle emissions, while spheres denote results calculated using a density of 310 µg/m3
