Abstract

HTPs are launched as products with no combustion; however, combustion cannot be avoided [1]. The aim of this study is to determine the particles emitted from a new HTP.

A commercial Pulze device is used. Sticks with 4 different flavours (Bronze, Bleu, Capsule Polar and Ice) are used, with the experiments repeated 3 times. Particles emissions are determined using a Dustrack (measuring PM1, PM2.5, Respirable particles, PM10 and total PM) and an Aethalometer (measuring black carbon). Each stick is puffed 10 times; the puff duration is 2” with an interval of 20” and a flow rate of 100 ml/min.

Fig 1 shows the percentage of each fraction to the total particles determined from the Dustrack (using one stick, the other show very similar results), while Fig 2 shows the particles emitted from the 4 sticks. Fig 1 shows that the majority of particles emitted from the four sticks are fine particles (PM1). This percentage decreases slightly at the latest puffs.

Fig 2 show that the emissions of the 4 sticks are quite similar and are, with some variations, quite constant between the 10 puffs. The emissions are in the range of 17-450mg/m3 and 200,000-3,500,000 ng/m3. The black carbon particles correspond to 3-11% of the total particles in the case of the three flavours and 10-65% in the case of Ice flavour.

The particles emitted are in the range of 17-450mg/m3 and 200,000-3,500,000 ng/m3; the flavour has no impact on these emissions, which are quite constant for the same stick for 10 puffs. However, the flavours used have an impact on the black carbon emitted.
