Cig Vapour Tested Positive For Lead And Arsenic In New Study

Significant amounts of lead and other toxic metals leak from some heating coils in e-cigarettes and contaminate aerosols that the user inhales, a new study suggests. The researchers, however, did find that fresh coils in e-cigarettes generate higher levels of aerosol metal concentrations. But after the liquid was heated into an aerosol, numerous samples had elevated levels of lead, chromium, nickel, manganese, and zinc. These materials, when inhaled chronically, have been linked to lung, liver, immune, cardiovascular and brain damage and cancers.

"It's important for the FDA, the e-cigarette companies and vapers themselves to know that these heating coils, as now made, seem to be leaking toxic metals - which then get into the aerosols that vapers inhale", Ana María Rule, told New Atlas.

The researchers also found arsenic in more than 10 percent of the liquid, liquid in the e-cigarette and aerosol it tested.

Well, the U.S Food and Drug Administration has all rights to control the usage of e-cigarettes but it is still a big question for the administration as well, that how it can be done. Concentrations of these metals were also elevated, though not as high, in the e-liquid left behind in the device. Evidence that vaping is not entirely safe continues, however, to accumulate. They first tested the e-liquid in the dispenser for 15 common metals. Researchers sampled 56 vape devices from IRL e-cig smokers. "Due to potential toxicity resulting from chronic exposure to metals in e-cigarette aerosols, additional research is needed to more precisely quantify metal exposures resulting from e-cigarette use and their implications for human health, and to support regulatory standards to protect public health".

During the study, researchers had worked on the sample which tells that the concentrations are higher than the limits based according to health habits by the EPA. In addition, the concentrations of nickel, chromium and manganese found in almost half of the aerosol samples exceeded the limits.

An estimated three million people in the United Kingdom and 10 million in the USA use e-cigarettes. How the arsenic got into these e-liquids is yet another mystery-and another potential focus for regulators.

The Johns Hopkinsteam is planning future studies on vaping and metal exposures.

The next step, Rule said in a release from Johns Hopkins, is to get to the bottom of whether these metals are harmful or not - and to present that data to regulators so they can make informed decisions.

The Maryland State Cigarette Restitution Fund, the Alfonso Martín Escudero Foundation, the American Heart Association Tobacco Regulation and Addiction Center, and the National Institute of Environmental Health Sciences funded the research.
