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.
Presence of Microplastic in Bottled Water from Mumbai Market
Researchers tested five top-selling bottled water brands in Mumbai and found microplastics in every single one, with particles averaging about 82 micrometers in size. The contamination was detected across all brands at similar concentrations, suggesting that bottled water — often marketed as pure — is a consistent route of microplastic exposure for consumers.
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 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.
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.
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.
Microplastics in small semi-industrial desalination stations and bottled waters: Human exposure and emerging health concerns
Researchers analyzed microplastic contamination in bottled water and small semi-industrial desalination stations in a water-scarce region. The study found microplastics present in both water sources, with higher levels than expected in desalination station output, raising concerns about human exposure through drinking water and highlighting the need for improved filtration standards.
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.
Analisis Mikroplastik Pada Air Minum Dalam Kemasan Di Kota Padang
Researchers analyzed microplastics in 30 bottled water samples from three brands in Padang, Indonesia, finding contamination in all samples at concentrations of 5-11 particles per liter. Fragment morphotypes dominated, followed by fibers and pellets, and significant differences in microplastic abundance were found between brands, raising consumer safety concerns in the Indonesian context.
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.
