ClearMicroplastic pollution and human risk assessment in Turkish bottled natural and mineral waters
This study analyzed 150 samples of bottled natural and mineral water sold in Turkey for microplastic contamination. Microplastics were found in all samples tested, with fibers being the most common type, and the study estimated the potential health risk to consumers. The results add to global evidence that bottled water is a consistent source of human microplastic ingestion, regardless of the country of origin.
Characterization of microplastics in sediments and surface waters of Turkish lakes
Researchers surveyed seven lakes in Turkey and found microplastics in all of them, with polyethylene and polypropylene being the most common types. Human activities like tourism, fishing, and urban waste disposal were identified as major sources, showing that even protected lake areas are contaminated with plastic particles that can enter drinking water supplies.
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 contamination in some beverages marketed in türkiye: Characteristics, dietary exposure and risk assessment
Researchers tested 47 different beverages sold in Turkey and found microplastics in about one in five samples, with cold tea showing the highest contamination levels. While the estimated daily intake from these beverages was considered a low physical health risk, the study confirms that packaged drinks are a routine source 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.
Microplastic pollution of drinking water in a metropolis
Researchers analyzed 100 drinking water samples from various sources across Istanbul and found microplastics in every sample, with concentrations ranging from 10 to 390 particles per liter. Eight different polymer types were identified, including polyethylene, polypropylene, and PVC, in both fiber and fragment forms. The findings indicate that drinking water in major metropolitan areas is a consistent pathway for human microplastic exposure.
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.
Detection, Quantification, and Characterisation of Microplastics in Maltese Bottled Water
Researchers detected microplastics in 84% of bottled water samples from five Maltese brands at an average concentration of 35,877 ± 23,542 particles per litre, with an average particle diameter of 2.37 μm and polymers including polyurethane, polyethylene, and polymethyl methacrylate identified by Raman spectroscopy.
Detection of Microplastics in Bottled Water
Researchers detected microplastics in bottled water samples from Sarawak, Malaysia, contributing to the limited data on bottled water contamination in Southeast Asia and highlighting potential human exposure through a widely consumed beverage.
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.
Prevalence of microplastics in commercially sold soft drinks and human risk assessment
Researchers tested ten brands of soft drinks sold in Turkey and found microplastics in every single one, with 80% of samples showing high contamination levels. On average, consumers are exposed to about nine microplastic particles per liter of soft drink, likely originating from the bottling process and packaging materials. This study adds soft drinks to the growing list of everyday beverages through which people regularly consume microplastics.
Occurrence of microplastics in bottled water from Croatia: a Raman spectroscopy approach
Researchers analyzed six brands of bottled water sold in Croatia and found microplastics in all of them, with particles as small as 1 micrometer detected using Raman spectroscopy. The most commonly found plastics were PET and polyethylene, and interestingly, bottles made from virgin PET contained more microplastics than those made from recycled PET. The study adds to growing evidence that bottled water is a significant source of human microplastic exposure.
A Comparative Study About the Amount of Microplastic in Polyethylene Terephtalate (pet) Drinking Water That Was Exposed and Not Exposed by Sun at Environmental Health Laboratory of Poltekkes Kemenkes Semarang at the Year 2020
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 Pollution and Risk Assessment in Packaged Teas in Türkiye
Researchers analyzed 15 packaged tea brands in Turkey and found microplastics in every single one, with the highest concentrations in dry tea leaves removed from the bags. PET was the most common plastic type, and fiber-shaped particles dominated. The study calculated that daily tea drinkers are regularly consuming microplastics, with men potentially exposed to more than women due to higher consumption, raising questions about this overlooked route of human exposure.
Quantification of microplastics in bottled water by Pyr-GC-Orbitrap-MS, human exposure, and in vitro hepatotoxicity assessment
Researchers analyzed 40 bottled water brands from five countries and found microplastics in 31 of them, primarily from bottle cap materials (HDPE plastic) rather than the PET bottles themselves, with the average adult exposure estimated at a very low 0.004 micrograms per kilogram of body weight per day — and lab tests showed this level caused no detectable liver cell damage.
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.

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 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.
