Figure 24: Conditions of general aerosols during burning of a candle on January 5-6: (a) ratio of the number concentration of aerosol particles smaller than 10 nm ((<10)) to that of bigger ones ((>10)) and ratio of the total surface area of all particles smaller than 10 nm ((<10)) to the total surface area of all particles bigger than 10 nm ((>10)) in a volume unit and (b) ratio of the number concentration of aerosol particles smaller than 20 nm ((<20)) to that of bigger ones ((>20)) and ratio of the total surface area of all particles smaller than 20 nm ((<20)) to the total surface area of all particles bigger than 20 nm ((>20)) in a volume unit.
