Comparative analyses of total particulate matter ( TPM) and volatiles in mainstream cigarette smoke ( CS) and water-filtered cigarette smoke (WF-CS) . (A) Quantification of TPM in mainstream CS and WF-CS by trapping particles from 1 cigarette on glass fiber filters. Data are expressed as mean values ± SEM and are referred to 4 experiments. *** P < 0.0001 for comparison between CS and WF-CS group. (B) Comparative analysis of CS and WF-CS using GC-MS. Characterization of the peaks at time 2.8 (component 1), time 3.56 (component 2), time 3.64 (component 3) and time 15.4 (nicotine) was done by mass spectrometry.
