Most particles come from bottles themselves and reverse osmosis filters, shedding plastics like PET and polyamide when opened or squeezed.
Nanoplastics bypass biological barriers, entering the bloodstream, brain and even the placenta, potentially causing inflammation, immune dysfunction and cancer.
Bottled water associations dismissed the findings, while global plastic production exceeds 430 million tons per year with no unified treaty to curb pollution.
Experts recommend avoiding plastic bottles, using stainless steel or glass containers and opting for filtered tap water (preliminary data shows lower contamination than bottled).
A groundbreaking study has revealed that the average liter of bottled water contains nearly a quarter of a million microscopic plastic particles—far more than previously estimated—raising urgent questions about potential health risks. Researchers from Columbia and Rutgers universities, publishing their findings in Proceedings of the National Academy of Sciences, used advanced laser microscopy to detect nanoplastics so small they evade conventional detection methods....<<<Read More>>>...
