PERTH: If you asked me what’s in e-cigarettes, disposable vapes or e-liquids, my short answer would be “we don’t fully know”.
The huge and increasing range of products and flavours on the market, changes to ingredients when they are heated or interact with each other, and inadequate labelling make this a complicated question to answer.
......
Despite these complexities, there are some consistencies between what different laboratories find.
Ingredients include nicotine, flavouring chemicals and the liquids that carry them - primarily propylene glycol and glycerine.
Concerningly, we also find volatile organic compounds, particulate matter and carcinogens (agents that can cause cancer)
......
Our previous research also found 2-chlorophenol in about half of e-liquids users buy to top-up re-fillable e-cigarettes. This is one example of a chemical with no valid reason to be there. Globally, it’s classified as “harmful if inhaled”. Its presence is likely due to contamination during manufacturing.
......
Polonium-210 can be found in traditional cigarettes and other tobacco products. That’s because tobacco plants absorb it and other radioactive materials from the soil, air and high-phosphate fertiliser.
Whether polonium-210 is found in aerosols produced by e-cigarettes remains to be seen. Although it is feasible if the glycerine in e-liquids comes from plants and similar fertilisers are used to grow them.
......
Aside from their ingredients, the materials e-cigarette devices are made from can end up in our bodies.
Toxic metals and related substances such as arsenic, lead, chromium and nickel can be detected in both e-liquids and vapers’ urine, saliva and blood.
These substances can pose serious health risks (such as being carcinogenic). They can leach from several parts of an e-cigarette, including the heating coil, wires and soldered joints.
