Figure 3

Distribution pattern of the mean concentrations (Cmean) after 10 min under different ventilation conditions. Percentage information of the PM fractions PM10−2.5, PM2.5−1, and PM1 are rounded to two decimal places. PM, Particulate matter; 3R4F, 3R4F reference cigarette; MR, Marlboro red; MG, Marlboro gold; C, Condition; C1, Windows closed, car ventilation off, outside fan off; C2, Window 10 cm opened, car ventilation on; C3, Window 10 cm opened, car ventilation on, outside fan turned on at highest power level; C4, Window half-opened, car ventilation on; C5, Window half-opened, car ventilation on, outside fan turned on at highest power level; C6, Window fully opened, car ventilation on; C7, Window fully opened, car ventilation on, outside fan turned on at highest power level.
