I agree and I would also be interested in knowing which brand cartomizers where tested and if they are still being sold

As a layman and electronic cigarette user this looks , at first glance, very scary.
I agree that it lacks some very important details including an actual comparison between electronic cigarette vapour and tobacco smoke. The only 'comparison' referred to isn't a comparison at all. They state that an EC user taking 100 puffs a day will inhale 10^8 particles < 1000nm. 10 puffs is equivalent to a tobacco cigarette so that would be 10^7 compared to the tobacco cigarette's 8.8 x 10^9 (nearly 10^10) particles. So are there about 1000 times more particles in the tobacco cigarette? There would be if they were making a comparison of the same sizes of particle. In fact, they compare the number of particles in tobacco smoke between 6 and 50nm with the number of particles in EC vapour <1000nm, a range that is over 20 times greater! It's as if these figures have been written to make ECs look much worse than they are compared with tobacco.

1. We have not yet determined the amounts absorbed by e-cigarette users, but plan to collect such data in the future.
2. We are currently determining the toxicity thresholds for the combined metals in aerosol.
3. Using transmission electron microscopy and electron diffraction, we determined that the silicates in this EC aerosol were amorphous.
