Drink under scrutiny as it may pose ‘potential health implications -…

The Spanish scientists acknowledged: “The potential health implications of environmental micro/nanoplastics (MNPLs) are increasingly concerning. Beyond environmental exposure, other sources such as food packaging, including herbal teabags, may also be significant.”

Released in the journal Chemosphere last 12 months, the research found that one teabag alone can discharge billions of microplastics into the human system. 

Throughout laboratory testing, the bulk of these fragments had been taken up by mucus-generating intestinal cells, though some managed to penetrate the cell nucleus, the placement where genetic info resides. 

The research workforce underscored the essential need for uniform testing protocols and tighter regulatory controls to sort out contamination, noting: “It is critical to develop standardised test methods to assess micro/nanoplastics (MNPLs) contamination released from plastic food contact materials and to formulate regulatory policies to effectively mitigate and minimise this contamination.”

They continued: “As the use of plastic in food packaging continues to increase, it is vital to address MNPLs contamination to ensure food safety and protect public health. Overall, our findings contribute to a growing body of evidence on the pervasive nature of plastic pollution and its potential implications for human health.”

For their investigation, researchers analyzed three generally bought teabag varieties – a nylon option sourced from Amazon, a polypropylene variant from AliExpress, and a grocery store teabag containing an undisclosed filter polymer.

During each trial, 300 luggage had been submerged in a 1-liter beaker containing 600ml of water warmed to 95C.
