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.
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.
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.
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.
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.
Polymers of micro- and nanoplastics in household tap water of Barcelona
Researchers quantified micro- and nanoplastic polymers in the 0.7-20 micrometer size range in household tap water from the public drinking water network of Barcelona, Spain, using a novel workflow designed to capture smaller particle sizes than most previous studies. The cross-sectional study found microplastics present in drinking water at concentrations relevant to human daily exposure assessment.
First evidence of microplastics in bottled water sold in Mexico
Researchers provided the first evidence of microplastic contamination in bottled water sold in Mexico, analyzing ten widely consumed commercial brands. They detected an average of 39.3 particles per liter, with most particles smaller than 500 micrometers, and PET and polypropylene were the dominant polymers, indicating that fragmentation of the bottles and caps is the primary contamination source. The study found that children are the most vulnerable population segment, with the highest relative microplastic intake normalized by body weight.
Smaller-sized micro-plastics (MPs) contamination in single-use PET-bottled water in Thailand.
This study quantified microplastics in ten brands of single-use PET-bottled water sold in Thailand, finding an average of 140 particles per liter using fluorescent staining. The results add to global evidence that bottled water is a consistent route of human microplastic exposure and suggest that plastic packaging is a likely contamination source.
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 microplastics (<10 μm) associated to plastic bottles mineral water consumption: The first quantitative study
Researchers conducted the first quantitative study of microplastic contamination in bottled mineral water and found that plastic bottles release significant numbers of particles smaller than 10 micrometers into the water. The release was linked to the bottle material and storage conditions. The findings suggest that drinking bottled water is a meaningful source of human microplastic exposure.
Estimated exposure to microplastics through national and local brands of bottled water in Central India
Researchers tested bottled water from national and local brands in central India and found microplastics in every single sample, with local brands containing about three times more than national brands. The most common particles were polyethylene and PET fragments, likely coming from the plastic bottles and caps themselves. The study estimated that people drinking bottled water in India could be consuming tens of thousands of microplastic particles per year, highlighting bottled water as a significant source of human exposure.
Synthetic Polymer Contamination in Bottled Water
Researchers tested 259 bottles of water from 11 major brands purchased across nine countries and found microplastic contamination in 93% of samples. The most common particles were fragments, with polypropylene from bottle caps being the dominant polymer type identified. The study suggests that bottled water is a widespread source of human microplastic exposure, with contamination likely occurring during the packaging process.
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.
Prevalence and health risks of microplastics in bottled water and beverages: A food safety concern
This review consolidates evidence on microplastic contamination in bottled water and commercial beverages, finding concentrations ranging from a handful to several hundred particles per liter depending on packaging material and beverage type. The most commonly detected polymers were PET, polypropylene, and polyethylene, primarily from bottle degradation and bottling processes, with children and frequent consumers facing increased exposure.
