Occurrence of microplastics in bottled water from Croatia: a Raman spectroscopy approach
AI summary Read the abstract
Researchers analyzed six brands of bottled water sold in Croatia and found microplastics in all of them, with particles as small as 1 micrometer detected using Raman spectroscopy. The most commonly found plastics were PET and polyethylene, and interestingly, bottles made from virgin PET contained more microplastics than those made from recycled PET. The study adds to growing evidence that bottled water is a significant source of human microplastic exposure.

Researchers detected microplastics in 84% of bottled water samples from five Maltese brands at an average concentration of 35,877 ± 23,542 particles per litre, with an average particle diameter of 2.37 μm and polymers including polyurethane, polyethylene, and polymethyl methacrylate identified by Raman spectroscopy.
Analysis of microplastics in water by micro-Raman spectroscopy: Release of plastic particles from different packaging into mineral water
AI summary Read the abstract
This study analyzed microplastics in water samples using micro-Raman spectroscopy and also investigated the release of plastic additives, finding that both microplastics and their leached chemicals are present in aquatic environments.
Identification of Poly(ethylene terephthalate) Nanoplastics in Commercially Bottled Drinking Water Using Surface-Enhanced Raman Spectroscopy
AI summary Read the abstract
Scientists developed a new detection method using enhanced Raman spectroscopy to identify nanoplastics in commercially bottled drinking water. They found PET nanoplastics averaging about 88 nanometers in size in the bottled water samples tested. This study provides concrete evidence that people are consuming nanoplastics through a common daily source, and offers a tool that could help monitor plastic contamination in beverages.
