ClearSingle Nanoplastics Detection and Nano-Chemical Analysis of Surface Degradation in Commercial Bottled Water
Researchers developed a novel analytical approach that can detect and characterize individual nanoplastic particles as small as 30 nanometers in commercial bottled water. The method combines fluorescence-guided nanoscale imaging with infrared nanospectroscopy to identify particle size, shape, chemical identity, and surface degradation. The study represents a significant advance in the ability to analyze nanoplastic contamination in real food and beverage samples at the single-particle level.
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.
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.
Identification of Poly(ethylene terephthalate) Nanoplastics in Commercially Bottled Drinking Water Using Surface-Enhanced Raman Spectroscopy
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.
Study of Analysis Method on Microplastic Identification in Bottled Drinking Water
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.
A review on the detection of micro and nano plastics in drinking water
This review assessed detection methods for micro- and nanoplastics in drinking water, covering both tap and bottled water where these contaminants have been widely documented. The authors evaluated current analytical techniques and identified gaps in standardized monitoring approaches.
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.
Occurrence of Microplastics in Tap and Bottled Water: Current Knowledge
This review summarizes current research on microplastic contamination in both tap and bottled drinking water. Researchers found that microplastics are present in both water sources, with bottled water generally containing higher concentrations than tap water, and smaller particles being more abundant. The study raises public health concerns and emphasizes the need for improved detection methods and drinking water treatment standards.
A review on the detection of micro and nano plastics in drinking water
This review covered detection methodologies for micro- and nanoplastics in drinking water, including both tap and bottled water sources. The authors synthesized current analytical approaches and highlighted the need for standardized methods across studies.
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.
Microplastics and nanoplastics contamination in raw and treated water
Researchers analyzed 189 samples of raw, tap, and bottled drinking water for micro- and nanoplastic contamination. They found plastic particles in every sample tested, with raw water sources containing the highest concentrations and treated tap water containing the lowest, though contamination was never fully eliminated. The study suggests that current water treatment processes reduce but do not completely remove plastic particles from drinking water.
Insights into Anthropogenic Micro- and Nanoplastic Accumulation in Drinking Water Sources and Their Potential Effects on Human Health
This review examines the growing body of evidence on micro- and nanoplastic contamination in drinking water sources, including both tap water and bottled water intended for human consumption. Researchers summarize the potential health effects of exposure through ingestion, inhalation, and skin contact, noting that current detection methods struggle with particles smaller than 10 micrometers. The study highlights the need for improved analytical tools and further research to fully understand the health implications of plastic particles in drinking water.

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 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.

Microplastic Contamination in Drinking Water: A Review
This review summarized current research on microplastic contamination in drinking water, covering detection methods, occurrence data, and health implications. The authors found microplastics widely present in tap and bottled water worldwide and noted that conventional treatment processes remove them incompletely, raising ongoing concerns about chronic low-level human ingestion.
Rapid single-particle chemical imaging of nanoplastics by SRS microscopy
Using a new high-speed imaging technique, researchers detected and identified nanoplastics in bottled water at the single-particle level, finding roughly 240,000 plastic particles per liter. This is far more than previously estimated and includes particles smaller than 100 nanometers made from common plastics, suggesting our exposure to nanoplastics from bottled water may be much higher than thought.
