Drinking water from plastic bottles may expose people to significantly higher levels of microplastics than previously understood, according to new scientific findings that are raising fresh questions about everyday health risks.
A recent research review indicates that individuals who regularly consume bottled water ingest more than 90,000 additional microplastic particles compared to those who rely on tap water, highlighting a growing public health concern linked to single-use plastics.
The findings were published in the peer-reviewed journal Journal of Hazardous Materials, which analyzed data from 141 scientific studies examining microplastics released from plastic bottles. Researchers estimate that the average person consumes between 39,000 and 52,000 microplastic particles annually, ranging in size from microscopic fragments to several millimeters.
Ongoing exposure and possible health implications
According to the study’s lead author, drinking bottled water may be unavoidable in emergency situations or where safe alternatives are unavailable. However, the research cautions against considering bottled water a safe option for routine, long-term consumption.
Scientists note that prolonged exposure to microplastics and nanoplastics may be linked to a range of chronic health conditions. These include respiratory illnesses, reproductive and fertility challenges, nervous system damage, cellular and hormonal disruption, neurological disorders, and a potential increased risk of cancer.
How microplastics interact with the human body
The research also highlights evidence suggesting that microplastic particles can enter the bloodstream and reach vital organs. Once inside the body, these particles may contribute to inflammation and other medical complications over time.
While the findings raise serious concerns, researchers stress that more long-term and comprehensive studies are required to fully understand the health and environmental impacts of bottled water consumption and microplastic exposure.
