Summary
Cigarette smoke particle size, measured by aerosol centrifuge and cascade impactor, showed a log-normal distribution. Increasing dilution decreased the mass median aerodynamic diameter of smoke particles.
Area of Science:
- Environmental Science
- Aerosol Science
- Public Health
Background:
- Cigarette smoke is a complex aerosol containing various particulate matter.
- Understanding the aerodynamic size distribution of cigarette smoke is crucial for assessing health risks and exposure.
Purpose of the Study:
- To determine the aerodynamic size distribution of cigarette smoke.
- To investigate the effect of dilution on the particle size of cigarette smoke.
Main Methods:
- Utilized an aerosol centrifuge and a cascade impactor for particle size measurement.
- Measured the aerodynamic size distribution across a range of dilutions (10:1 to 700:1).
Main Results:
- The aerodynamic size distribution of cigarette smoke followed a log-normal pattern.
- Mass median aerodynamic diameter decreased from 0.52 to 0.38 μm with increased dilution.
- Average geometric standard deviation was consistently 1.38.
Conclusions:
- Dilution significantly impacts the measured aerodynamic size of cigarette smoke particles.
- Discrepancies with previous studies are likely due to variations in experimental methodologies.
