“Boiling Tap Water Removes Up to 90% of Microplastics, Study Finds” — what this page in the network covers. A new study published in Environmental Science & Technology Letters reveals a simple, at-home method to significantly reduce microplastics in drinking water: boiling. Researchers from Guangzhou Medical University and Jinan University found that boiling hard tap water for five minutes and then filtering out the precipitated calcium carbonate can remove up to 90% of nano- and microplastics. The process works because limescale, which forms when hard water is boiled, traps plastic particles as it solidifies.
Even in soft water, where less calcium carbonate is present, boiling still removed around 25% of microplastics. Given that the average person consumes thousands of microplastic particles annually through water and food, this low-cost technique could help mitigate potential health risks, including inflammation and gut microbiome disruption.
