Potentially unsafe levels of toxic chemicals were found in e-cigarette vapers, according to a recently released study.
Researchers at Johns Hopkins Bloomberg School of Public Health tested e-liquids in vapers’ refilling dispensers coming from 56 Baltimore-area daily e-cigarette users for a study published Wednesday within the peer-reviewed journal Environmental Health Perspectives.
After testing for the presence of 15 metals, researchers found significant levels of highly toxic arsenic in 10 of the samples. Significant levels (nearing or exceeding current health-based limits) of chromium, manganese, nickel as well as lead were found in about half of the samples. Aerosol metal concentrations were also highest for e-cigarettes with more frequently changed coils, study authors found.

“the item’s important for the FDA, the e-cigarette companies as well as vapers themselves to know of which these heating coils, as currently made, seem to be leaking toxic metals — which then get into the aerosols of which vapers inhale,” said study senior author Ana María Rule, assistant scientist within the Bloomberg School’s Department of Environmental Health as well as Engineering.
The Food as well as Drug Administration has the authority to regulate e-cigarettes as well as e-liquids.
The Johns Hopkins team can be planning future studies on vaping as well as metal exposures. More research must be done to determine possible health effects.
