Microplastics in Spanish bottled water
Researchers analyzed 22 bottled water samples sold in Spain -- packaged in plastic, glass, and cans -- by filtering entire bottle volumes and characterizing particles via micro-FTIR, finding microplastic concentrations of 0-27 particles/L (median 6.67 particles/L) with cellulosic fibers, polyamide, and PET as the dominant polymer types.
FTIR-Based Identification of Microplastics in Commercial Bottled Drinking Water
Scientists found tiny plastic particles in all 10 brands of bottled water they tested, using a special technique to identify the plastic types. These microplastics likely come from the plastic bottles and packaging process itself. While we don't yet know the full health effects of drinking these plastic particles, this study shows that even bottled water isn't free from plastic pollution.

Researchers detected and characterized microplastics in bottled water from different packaging types using Raman spectroscopy, confirming that plastic contamination occurs across various commercial water bottle materials.
Detection, Quantification, and Characterisation of Microplastics in Maltese Bottled Water
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.
Validation of an FT-IR microscopy method for the monitorization of microplastics in water for human consumption in Portugal: Lisbon case study
Researchers validated a method using infrared microscopy to monitor microplastics in drinking water and applied it to 60 tap water samples from Lisbon, Portugal. They detected microplastics in most samples, with an average of 309 particles per liter, predominantly polyethylene fragments averaging 76 micrometers in length. The study provides one of the first standardized approaches for routine microplastic monitoring in public water supplies, an important step for assessing human exposure.
Early screening of suspected microplastics in bottled water in the Santiago Metropolitan Region of Chile
Researchers screened multiple brands of bottled water sold in Santiago, Chile, for microplastic contamination using fluorescence microscopy. They detected suspected microplastic particles in all tested brands, with concentrations varying significantly between products. The findings add to growing global evidence that bottled water, often perceived as a cleaner alternative to tap water, may be a meaningful source of human microplastic exposure.
Occurrence of microplastics in bottled water from Croatia: a Raman spectroscopy approach
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.
