Evaluation of the performance of Nanoparticle Tracking Analysis (NTA) for the measurement of nanoplastics

Researchers developed and tested a method called nanoparticle tracking analysis (NTA) for detecting nanoplastics — plastic particles smaller than one micrometer — and applied it to eight brands of bottled mineral water. While the technique successfully detected particles in the 110–170 nanometer range in every brand tested, the method cannot distinguish plastic from other natural particles, so the results represent total particle content rather than confirmed nanoplastic counts.
