FTIR-Based Identification of Microplastics in Commercial Bottled Drinking Water
Scientists found tiny plastic particles in all 10 brands of bottled water they tested, using a special technique to identify the plastic types. These microplastics likely come from the plastic bottles and packaging process itself. While we don't yet know the full health effects of drinking these plastic particles, this study shows that even bottled water isn't free from plastic pollution.
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.
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.
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.
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.
Prevalence and health risks of microplastics in bottled water and beverages: A food safety concern
This review consolidates evidence on microplastic contamination in bottled water and commercial beverages, finding concentrations ranging from a handful to several hundred particles per liter depending on packaging material and beverage type. The most commonly detected polymers were PET, polypropylene, and polyethylene, primarily from bottle degradation and bottling processes, with children and frequent consumers facing increased exposure.
Characteristics of nano-plastics in bottled drinking water.
Researchers detected nanoplastics in commercially bottled drinking water using novel nanoparticle analysis techniques, finding particles in the nanometer size range in multiple brands. These findings are concerning because nanoplastics are thought to be more biologically active than larger microplastics and can more easily cross biological barriers in the body.
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.
