Lead and other toxic metals found in e-cigarette 'vapors'

Today the word on the e-streets is that E-Cigarette Vapor Found To Have Potentially Toxic Levels Of Lead & More. But after the liquid was heated into an aerosol, numerous samples had elevated levels of lead, chromium, nickel, manganese, and zinc.

Of the metals significantly present in the aerosols, lead, chromium, nickel, and manganese were of most concern, as all are toxic when inhaled.

Chronic exposure to metals such as those found in the study have been linked to negative effects on the lungs, brain, heart, liver, and immune system.

When e-cigarettes entered the market, a flurry of studies suggested they could be much safer than tobacco cigarettes.

Although the study was small, the authors say its findings are important and warrant evaluation by the Food and Drug Administration (FDA) due to the potential health consequences of exposure to these metals.

The heating coils inside e-cigarette devices can leak toxic metals including lead - and the metals are found in the vapour inhaled by users, a new study has found.

Vaping is popular in part because it provides a nicotine "hit" and the look and feel of tobacco smoking, but without some of smoking's extreme health risks. The process creates an aerosol, which contains vaporized e-liquid and tiny liquid droplets.

Johns Hopkins University's Bloomberg School of Public Health has released a study that proves toxic chemicals are released when heating the coils in a vape pen. They first tested the e-liquid in the dispenser for 15 common metals. Four metals were excluded because of low levels: arsenic, titanium, uranium and tungsten.

Then they tested the aerosol that users inhale into their lungs, which is generated by the e-liquid being heated by a battery-powered metal coil.

Although minimal levels of metals were found in the e-liquids within refilling dispensers, the metal contamination transferred to aerosols produced by heating the e-liquids.

The median lead concentration in the aerosols, for example, was more than 25 times greater than the median level in the refill dispensers.

The data showed that almost 50 percent of aerosol samples contained lead in quantities above the Ambient Air Quality Standards set by the Environmental Protection Agency. Similarly, median aerosol concentrations of nickel, chromium and manganese approached or exceeded safe limits. The researchers also said that the concentration of e-cigarettes was higher with the ones who frequently used fresher coils. How the arsenic got into these e-liquids is yet another mystery-and another potential focus for regulators. Researchers aren't sure where it came from or why regulators didn't find it sooner.
