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.
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.
Worldwide bottled water occurrence of emerging contaminants: A review of the recent scientific literature
Microplastics in the 1-5 µm range are the most prevalent contaminants in bottled water, with water in plastic bottles consistently more contaminated than in glass bottles; while most other contaminant levels (pharmaceuticals, PFAS, BPA) fell below safety thresholds, synergistic effects of multiple contaminants remain unknown.
Unbottling the risk: Microplastic release and health hazards from bottled drinks
Researchers measured microplastic contamination in 14 commercial beverages—including water, milk, cola, juice, and vinegar—under varied temperature and storage conditions, and assessed toxicological risks. Microplastic concentrations varied significantly by beverage type and storage conditions, with higher temperatures and longer storage times increasing particle release from packaging materials.
Microplastics in Malaysian bottled water brands: Occurrence and potential human exposure
Researchers tested eight major bottled water brands sold in Malaysia and found microplastic particles in all of them, with concentrations varying significantly between brands. The most common types were fragments and fibers made of polyethylene and polypropylene. The study estimates daily microplastic intake from bottled water consumption and highlights the need for quality standards addressing microplastic contamination in drinking water.
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.
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.
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.
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.
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.
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.
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.
Identification, Quantification, and Presence of Microplastics and Nanoplastics in Beverages Around the World
Researchers reviewed studies from around the world examining microplastics in beverages including water, beer, soft drinks, and other drinks. They found microplastics were present in virtually all beverage types tested, with concentrations ranging widely and particles originating from water sources, packaging materials, and processing surfaces. The findings raise concerns about ongoing low-level human exposure through everyday drinks.
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.
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.
Microplastics contamination in food and beverages: Direct exposure to humans
This review analyzed 108 studies on microplastic contamination in food and beverages, finding that humans are exposed through seafood, salt, drinking water, bottled water, and packaged foods. Bottled water showed particularly wide-ranging contamination levels of up to 6,292 particles per liter. The study concludes that dietary ingestion of microplastics is a significant and unavoidable exposure route that warrants further investigation.
Occurrence and health risk assessment of microplastics in beverages and ice packs
Researchers found an average of 183 microplastic particles per liter in beverages and 179 particles per liter in ice packs, mostly polypropylene and PET from packaging. Adults are estimated to consume about 5.5 microplastic particles per kilogram of body weight daily through beverages, making packaged drinks a significant and underappreciated source of human microplastic exposure.
MPs in drinking water and beverages: Concentrations, characteristics and implications for human exposure
Researchers reviewed 10 years of studies on microplastics in drinking water, bottled water, tea, coffee, and other beverages, finding that contamination levels vary widely by region, packaging type, and how hot the liquid gets.
