Hi,

Thanks Avi, that's great! Already the first paper by Fuoco et al. was exactly what I was looking for.

be in touch with prof. Najat Saliba at the AUB.

Thanks Tareq! Prof. Najat A Saliba really is a new reference to me. So far I have only met Prof. Alan Shihadeh and people from his aerosol group at AUB. I will teach out to Prof. Saliba.

Best, Oliver

Here is a recent study by Schober et al.: doi: 10.1016/j.ijheh.2013.11.003

I am not sure it there is any publication yet that reliably tells the particle size distribution of e-cigarettes and I doubt that there is any publication that based on the particle size distribution gives a reasonable health risk analyse:

1) e-cigarette vapor is completely volatile (by measuring the psd high dilution is required in order to prevent coagulation artefacts)

2) deposition in the human respiratory tract is based on particle size; however, e-cigarettes have a high potential of higroscopic growth but may also completely evaporate depending on their concentration. Equilibrium (in terms of phase transition) models can not be applied here, but most lung deposition models that consider phase transition are equilibrium models

I conclude: tricky topic
