ClearUnbottling 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.
Investigate the presence of plastic particles in bottled and reused water bottles for several times and medical feeder bottles
Researchers detected microplastics in bottled water, particularly in bottles that were reused multiple times or exposed to direct sunlight. PET bottles leached more microplastic particles under heat and UV stress, and particle counts increased with reuse cycles. This study highlights sunlight and mechanical wear as key factors increasing microplastic contamination in drinking water.

Researchers compared the amount of microplastics released from different brands and conditions of PET water bottles, finding that UV exposure and bottle age affect how many particles leach into the water. This study highlights bottled water as a direct route of microplastic ingestion for consumers.
Microplastic Contamination in Refillable and Packaged Drinking Water: Sources, Types, and Health Impacts
Researchers reviewed microplastic contamination in both refillable and packaged drinking water, examining sources, types, and health implications. The review found microplastics are consistently present in both water types, with packaging materials and distribution infrastructure identified as key contamination sources.

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.
Photodegradation-driven microparticle release from commercial plastic water bottles
Researchers exposed seventy PET plastic water bottles to sunlight for ten weeks and measured the microparticles released into the water as the plastic degraded. They found that microparticle concentrations built up to 14-20 micrograms per liter within the first 30 days before plateauing, and that thinner-walled bottles with higher crystallinity released fewer particles. The study demonstrates that sunlight-driven degradation of plastic bottles is a meaningful source of microplastics in bottled drinking water.
Generation of microplastics from the opening and closing of disposable plastic water bottles
Researchers found that the physical act of opening and closing disposable plastic water bottle caps releases microplastic particles into the bottle contents, with particle counts increasing with repeated use and mechanical wear.
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.
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.
Everyday storage and handling of PET bottled water increase human exposure to nano- and microplastics: Influence of socio-economic factors
Researchers tested eight major U.S. bottled water brands and found that everyday conditions like heat exposure and shaking dramatically increased nano- and microplastic release from PET bottles, with nanoparticle concentrations rising over ninefold under combined heat and agitation. A survey of over 1,600 people in Nebraska revealed that higher awareness of microplastics and education levels correlated with behaviors that reduce exposure, such as avoiding bottled water storage in hot conditions.
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.
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.
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.
Investigating the pollution of bottled water by the microplastics (MPs): the effects of mechanical stress, sunlight exposure, and freezing on MPs release
Researchers analyzed 23 popular Iranian brands of bottled water and found microplastic contamination in all samples, averaging about 1,500 particles per liter with over 90 percent smaller than 10 micrometers. Mechanical stress on bottles significantly increased microplastic release, while sunlight exposure caused the most polymer degradation. The study indicates that regardless of brand or source, bottled water contains hundreds to thousands of microplastic particles per liter.
