Physical Properties of Waterpipe Tobacco Smoke Particles Larger than 500 nm
The purpose of the study was to characterize the physical properties of waterpipe tobacco smoke (WTS) larger than 500 nm. Studies on particulate matter (PM) has shown that exposure to finer particles, increases its toxicity even if the particles have the same chemical composition. The size distribution of WTS PM over time was determined using the Optical Particle Sizer (OPS) and the mass distribution was determined using the DustTrak. The effects of different heating methods and different head contents on the WTS PM properties was also examined and compared to the baseline, charcoal and shisha.
