Nanoplastic Contamination in Bottled Water | 11 Jan 2024

The latest United States study reveals an alarming reality about bottled water, uncovering the presence of hundreds of thousands of nanoplastic particles underscoring potential health risks.

Each liter of bottled water contains 110,000 to 370,000 nanoplastic particles. About 90% of these particles are nanosized, posing a higher risk to human health.
Nanoplastics are even smaller than microplastics, ranging below 1 micrometer in size.
- Unlike microplastics (ranging between 5 millimeters and 1 micrometer), nanoplastics can move from the intestines and lungs directly into the bloodstream before reaching the heart and brain.
The study found that common plastics in bottled water such as polyamide, polypropylene, polyethylene, polyvinyl chloride, polyethylene terephthalate (PET) could play a significant role in micro-nano plastics exposure from bottled waters.
- PET used in disposable beverage bottles could leach into water when exposed to heat or squeezed.
