Is secondhand smoke of Customized elf bar 1500 electronic cigarette harmful?

Customized elf bar 1500 Electronic cigarette smoke is mainly formed by atomization of plant glycerin, which is basically harmless to human body, and electronic cigarette smoke has no major harmful substances such as tar carbon monoxide. However, the different components in cigarette bombs and cigarette oil may contain trace or constant amounts of heavy metals, and the metal properties are relatively active, which will be oxidized into metal ions in aerobic environment and at room temperature. Metal ions can be dissolved in the tobacco oil, and with the tobacco oil atomization, they enter into the smoke aerosol to be inhaled. And metal ion migration is often talked about in electrochemistry. It is an electrochemical phenomenon related to solution and potential. The solution is a conductor, and the metal ion migration is very obvious. In short, the Customized elf bar 1500 electronic cigarette oil body is originally insulated, but because of the presence of water molecules, metal ions will move from one pole to the other under power-on conditions, forming metal or metal compounds. This phenomenon also exists in PCB circuit boards. If the heating wire oxidizes to produce metal oxides, it will also react with some acidic substances in the tobacco oil, turn into organic metal compounds and enter the tobacco oil, and finally enter the aerosol. This means that the metal in the smoke does not necessarily refer to particles, but also includes heavy metal ions. In China, there are many testing institutions that can do heavy metal testing, and the draft of the suspected national standard also stipulates strict heavy metal emission standards. If the electronic cigarette is labeled black because of an unproven pathological study, it is likely to lead to excessive interpretation by the mass media, and then cause many people's incomprehension and panic about the electronic cigarette.
