Machine learning-supported detection, FTIR characterization and estimated dietary intake of microplastics in bottled water and beverages in western Mexico

Microplastic pollution in bottled water: a systematic review

AI summary · Read the abstract

Researchers systematically reviewed global studies on microplastic contamination in bottled drinking water, finding microplastics in 56–100% of analyzed samples with polyethylene terephthalate as the dominant polymer, and identifying a critical research gap around health risk quantification for consumers.

Detection of microplastics from food and beverage packaging materials

Microplastic Release from Plastic Bottles - Comparison of Two Analytical Methodologies (SEM-EDX and μ-FTIR)

AI summary · Read the abstract

Researchers compared two analytical methods for measuring microplastics released from plastic water bottles, finding that both scanning electron microscopy and infrared spectroscopy can detect these particles but differ in the types of information they provide. Their findings confirm that plastic bottles are a direct source of microplastic exposure through drinking water.

Physicochemical and statistical analysis of water and microplastics in a drinking water reservoir in México

AI summary · Read the abstract

Researchers detected microplastics at multiple depths in the Valle de Bravo reservoir in Mexico, a key source of drinking water for Mexico City and Toluca, finding that contamination varied by season and water depth. The presence of microplastics in a major drinking water supply highlights the challenge of protecting treated tap water from plastic contamination.

Microplastic Contamination and Life Cycle Assessment of Bottled Drinking Water

AI summary · Read the abstract

Researchers analyzed microplastic contamination in bottled drinking water and found that the plastic packaging itself releases microplastic particles that can enter the human body and cause oxidative stress in tissues — raising questions about whether bottled water, widely assumed to be clean, may be a significant source of plastic exposure.
