BACKGROUND: To evaluate secondhand smoke (SHS) contribution on indoor Particulate Matter (PM) concentrations due to a single smoked cigarette in a real exposure scenario. METHODS: Total Suspended Particles (TSP) and sizes ≤10 (PM(10)), ≤4 (PM(4)), ≤2.5 (PM(2.5)), and ≤1 μm (PM(1)) levels were measured before, during and after smoking in an enclosed smoke-free environment. The measurement was stopped 30 minutes after extinguishing the cigarette, to focus the monitoring just on SHS. RESULTS: PM(1) concentrations dramatically increased during and 30 minutes after smoking (mean values: 21.1, 1544.0 and 279.0 μg/m3 before, during and after, respectively), while the other PM fractions remained almost unchanged. CONCLUSIONS: This experiment implies that smoking even one cigarette produces important indoor air pollution which may considerably increase individual exposure to ultrafine particles, and, consequently, pose a serious threat to health.
