ClearMicroplastics and non-natural cellulosic particles in Spanish bottled drinking water
Researchers analyzed five top-selling bottled water brands in Spain and found microplastics in all of them, primarily polyester and polyethylene particles likely originating from the PET bottles and caps. While the estimated daily intake from bottled water alone was relatively low, the study adds to evidence that bottled water is a consistent source of microplastic exposure for consumers.
Analysis of the presence of microplastics in different brands of bottled water in Regional 6 - Ecuador
Researchers analyzed 72 water samples from four brands of bottled water in Ecuador's Region 6 for microplastic content using FTIR spectroscopy.

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.

Preliminary study of microplastic in bottled drinking water
Researchers investigated microplastic contamination in five brands of bottled drinking water from South Tangerang, Indonesia, using digital microscopy and micro-FTIR analysis.

Characterization of microplastics in water bottled in different packaging by Raman spectroscopy
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.
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.
Occurrence of microplastics in commercially sold bottled water
Researchers used advanced infrared spectroscopy to measure microplastics in commercially sold bottled water in China. They found microplastic particles in the samples, with concentrations varying by brand and bottle type. The study adds to growing evidence that bottled water is a significant source of human microplastic exposure, and it estimated the amount people may be consuming daily through this route.
What's in your water? A comparative analysis of micro- and nanoplastics in treated drinking water and bottled water
Researchers developed a novel method to detect both micro- and nanoplastics in drinking water using scanning electron microscopy and advanced infrared spectroscopy capable of identifying particles as small as 300 nanometers. The study found that bottled water had significantly higher concentrations of plastic particles than treated tap water, particularly for smaller micro- and nanoplastics, with polyamide, PET, and polyethylene being the most common polymers.

This study tested two methods for identifying microplastics in bottled drinking water using FTIR spectroscopy and thermal analysis. Microplastics were successfully detected, adding to evidence that bottled water is a source of human microplastic ingestion.
Occurrence and characterization of microplastics in bottled drinking water
Researchers analyzed microplastics in ten bottled water brands and found up to nine microplastic particles per liter, estimating that people who drink only bottled water may ingest over 150 microplastic particles per year — with polypropylene and polystyrene being the most common types found.

Scientists in a developing country analyzed 10 brands of bottled drinking water and found microplastics in all samples, with concentrations varying by brand. The most common particles were polyethylene and polypropylene fragments and fibers, likely originating from the plastic bottle caps and packaging. This study adds to evidence that bottled water is a significant source of daily microplastic intake for people worldwide.

Characteristics of nano-plastics in bottled drinking water.
Researchers detected nanoplastics in commercially bottled drinking water using novel nanoparticle analysis techniques, finding particles in the nanometer size range in multiple brands. These findings are concerning because nanoplastics are thought to be more biologically active than larger microplastics and can more easily cross biological barriers in the body.
