Nowadays, e-cigarettes are largely used, they are considered less dangerous than the traditional cigarettes. Actually, there are a lot of investigations on the health effects of nanoparticles and smoke emitted by them whereas there are very few studies on the e-liquid composition. For the first time this paper would like to investigate the inorganic composition of the e-liquids at different nicotine content (0, 9 and 18 mg mL−1) by means of the...
