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 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.
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 prevalence and human exposure in the bottled drinking water in the west Godavari region of Andhra Pradesh, India
A study of nine bottled water brands in India found an average of about 2.9 microplastic particles per liter, mostly fibers made of polypropylene and PET plastic. Children face higher daily exposure relative to their body weight than adults, and lifetime intake estimates suggest significant cumulative exposure through bottled water alone -- underscoring the importance of understanding microplastics in drinking water sources.
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.
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.
Synthetic Microplastics in UK tap and bottled water; Implications for human exposure
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.
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.
