Researchers at the Illinois Sustainable Technology Center analyzed fourth-generation vaping devices and discovered toxic heavy metals, including lead, within the devices' liquids. The study, published earlier this year, noted these contaminants were most prevalent in the lowest-cost brands.
Why it matters
The findings underscore environmental and public health risks associated with the increasing proliferation of disposable vaping devices. Beyond potential inhalation exposure, improper waste management of these electronics has been linked to fire hazards and wildlife threats.
Analysis of fourth-generation vaping devices revealed lead, zinc, copper, nickel, and aluminum in liquid solutions. Researchers pinpointed the presence of lead even in brand-new devices by examining structural components such as solder joints.
The players
Illinois Sustainable Technology Center
An applied research facility focused on sustainable energy, waste management, and environmental safety.
The details
Researchers extracted liquid solutions from discarded and new devices to identify the contaminants. The study indicates that structural degradation or leaching from internal components like solder joints—the metal alloys used to connect electronic parts—likely introduces lead into the nicotine solution. Exposure to these metals is known to impact tissue in the human heart, liver, skin, kidneys, and brain.
Timeline
Last year: Improper vaping device disposal caused record high numbers of fires at garbage sites in the United Kingdom.
Earlier this year: Researchers co-authored the study on heavy metals in vapes.
The Tech Race
This research follows the pattern set by the record high number of fires at garbage removal sites in the United Kingdom linked to improper vape disposal. It expands the scope of the field from simple battery waste concerns to include long-term environmental toxicological hazards.
Consumers should be aware that the most affordable vaping brands tested contained the highest levels of metal contaminants. Proper disposal remains critical, as the electronics pose both fire risks at waste sites and potential long-term bioaccumulation hazards for wildlife.
The takeaway
These findings highlight a significant oversight in the safety of disposable electronics currently reaching the market. Watch for future studies investigating the manufacturing processes responsible for these heavy metal contaminants.
What happens next
Future research may investigate the specific manufacturing origins of the heavy metals identified in these devices.
