ClearOccurrence 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.
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.
First evidence of microplastics and their characterization in bottled drinking water from a developing country
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.
Microplastic as an written composition in bottled water: Implications for waste management
This study characterized microplastic contamination in bottled water, identifying common polymer types and particle sizes and discussing implications for waste management and the effectiveness of current filtration in bottling facilities.
Exposure to micro(nano)plastics polymers in water stored in single-use plastic bottles.
Researchers quantified micro(nano)plastics ranging from 700 nm to 20 µm in bottled water from 20 popular Spanish brands, assessing daily consumer exposure risk and raising concern about the widespread presence of plastic polymer particles in single-use bottled water.
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.
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.
Microplastics in bottled water: assessing drinking safety in Nepal
Researchers quantified microplastics in 17 brands of bottled drinking water from five provinces of Nepal using vacuum filtration, finding particles in all brands with concentrations and polymer types suggesting contamination during bottling and from cap materials.
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.
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.
Assessing exposure of the Australian population to microplastics through bottled water consumption
Researchers analyzed 16 brands of bottled water sold in Australia and found microplastics present across all samples tested. The study identified polyethylene, polypropylene, and polystyrene particles, with concentrations varying between brands and water sources. The findings provide the first assessment of microplastic exposure through bottled water consumption for the Australian population and raise questions about the safety of this common drinking water source.
First assessment of occurrence, characteristics and human exposure of microplastics in bottled drinking water, Nepal
Researchers conducted the first assessment of microplastics in bottled drinking water from Nepal's mountain, hill, and Terai regions, finding microplastics in all 35 samples tested (mean 118 items/L), with fiber-shaped particles dominating at 71.76%, establishing a baseline for this developing-country context.
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.
New threats in food products: micro- and nanoplastics are food and water contaminants
This review examines micro- and nanoplastics as emerging food and water contaminants, covering how small synthetic polymer particles pass through filter systems and enter bottled water and beverages. It summarizes evidence of their environmental persistence and potential toxicity, and calls for research on their degradation patterns in different media to better assess food safety risks.
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.
Occurrence and Potential Health Risks Due to Trihalomethanes and Microplastics in Bottled Water
Researchers found microplastics and trihalomethanes in all tested Indian bottled water brands, with microplastic counts of 20-127 particles per liter and estimated yearly microplastic intake of 153 grams per person through bottled water consumption.
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.
Small-sized microplastics and pigmented particles in bottled mineral water
Researchers tested bottled mineral water and found microplastics and pigmented particles present, suggesting that plastic packaging itself may be a source of contamination in commercially sold water.
Microplastics 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.
Microplastics in Drinking Water
This review examines published evidence on microplastic presence in tap water, bottled water, and drinking water treatment plants, summarizing known pathways by which microplastics enter drinking water supplies and discussing potential human health impacts and future research priorities.
