ClearEstimated 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.
Occurrence and Assessment of Human Exposure to Microplastic Particles in Bottled Water From Southwest, Nigeria
Researchers tested eight brands of bottled water from southwest Nigeria and found microplastics in all of them, averaging about 15 particles per liter, mostly in the form of fibers. Children were estimated to consume three to four times more microplastics per kilogram of body weight than adults from bottled water. The study adds to growing evidence that bottled water is a significant source of human microplastic exposure, especially for children.

The study estimates daily microplastic intake from bottled water consumption and highlights the need for quality standards addressing microplastic contamination in drinking water.
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.
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.
Presence of Microplastic in Bottled Water from Mumbai Market
Researchers tested five top-selling bottled water brands in Mumbai and found microplastics in every single one, with particles averaging about 82 micrometers in size. The contamination was detected across all brands at similar concentrations, suggesting that bottled water — often marketed as pure — is a consistent route of microplastic exposure for consumers.
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.
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 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.
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.

Researchers tested 177 tap water samples from 13 UK cities and 85 bottled water samples from 17 brands, finding microplastics in every single sample with no meaningful difference in average concentration between tap and bottled water. Infants and toddlers were estimated to ingest four times more microplastics per kilogram of body weight than adults, raising concerns given their still-developing immune and nervous systems.
The effects of storage time and sunlight on microplastic pollution in bottled mineral water
Bottled mineral water was found to contain a mean of 63.9 microplastic particles per liter, with pellet forms and particles under 100 micrometers predominating. Storage under direct sunlight for extended periods increased microplastic concentrations by 2.5%, and the estimated daily intake was higher for children than adults due to relative body weight differences.
Insights into human exposure to microplastics through drinking water: Current state of the science
This review analyzed 66 studies on microplastics in drinking water from 2018 to 2023 and found that tap water actually contained more microplastics on average (about 62 particles per liter) than bottled water (about 38 particles per liter). Most particles were small fragments and fibers made of common plastics like PET, polyethylene, and polypropylene. The researchers estimate that people ingest roughly 175 microplastic particles per day just from drinking water alone.
Occurrence, Characteristics, and Risk Assessment of Microplastics in Tap Water and Bottled Water, China
This systematic review found microplastic contamination in both tap water and bottled water across China, with bottled water showing especially high levels — up to nearly 9,000 particles per liter for the smallest sizes. Fibers and fragments were the most common forms, and packaging degradation was a major contributor in bottled water. The findings raise practical concerns about microplastic exposure from the water we drink every day.
Occurrence and Source of Microplastics Contamination in Drinking Water and Performance of Water Treatment Plants in Removing Microplastics
This review summarizes evidence that microplastics are present in both tap water and bottled water worldwide, with bottled water frequently contaminated by particles shed from the plastic packaging itself. Conventional water treatment plants remove between 40% and 93% of microplastics but cannot eliminate them entirely, meaning treated drinking water still carries measurable plastic loads. The chapter highlights the irony that plastic packaging intended to deliver clean water is itself a major source of microplastic contamination.
