ClearInsights 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 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.
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.
Unveiling the hidden chronic health risks of nano- and microplastics in single-use plastic water bottles: A review
This review examines how single-use plastic water bottles release micro- and nanoplastics into drinking water, with bottled water consumers potentially ingesting up to 90,000 more plastic particles per year than tap water drinkers. The research links chronic exposure to these tiny plastic particles with respiratory diseases, reproductive issues, brain toxicity, and cancer risk, though more standardized testing methods are still needed.
Microplastic exposure disparities in California communities through bottled water consumption
This systematic review found that bottled water contains significantly more microplastics than tap water, and that minority and lower-income communities in California who rely more heavily on bottled water face disproportionately higher exposure. The findings highlight that efforts to avoid contaminated tap water may actually increase microplastic intake.
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.
Analytical Review of Microplastics Occurrence in Bottled Water, Tap Water, and Wastewater Treatment Plants
This review analyzes microplastic contamination across bottled water, tap water, and wastewater treatment plants using data from studies worldwide. Researchers found that microplastic levels in drinking water are closely tied to the water source and that packaging type significantly influences contamination, with glass bottles recommended over plastic. The study emphasizes the need for improved water treatment technologies and greater public awareness about microplastic exposure through drinking water.
Occurrence of microplastics in tap and bottled water, and food packaging: A narrative review on current knowledge
This narrative review compiled findings on microplastic contamination in tap water, bottled water, and food packaging. Researchers found that various types of microplastic fragments have been detected in drinking water sources worldwide, with bottled water generally containing more particles than tap water. The review highlights that food packaging is an additional source of daily microplastic exposure, underscoring the need for better monitoring and regulation.
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.
Human Consumption of Microplastics
Researchers evaluated the American diet and estimated that the average person consumes between 39,000 and 52,000 microplastic particles per year through food alone, with the number rising significantly when inhalation and bottled water consumption are included. The study analyzed data from 26 prior studies covering common food categories. The findings highlight that microplastic exposure through everyday eating and drinking is widespread and substantial.

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.
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.
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.
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.
