Identification and Quantification of Microplastics in Beverages in New Zealand
AI summary Read the abstract
Researchers identified and measured the quantities of microplastics — tiny plastic fragments less than 5mm — present in beverages available in New Zealand. The full findings are restricted to authenticated university members, but the work adds to growing evidence that microplastics are entering the human food and drink supply.

Identification, Quantification, and Presence of Microplastics and Nanoplastics in Beverages Around the World
AI summary Read the abstract
Researchers reviewed studies from around the world examining microplastics in beverages including water, beer, soft drinks, and other drinks. They found microplastics were present in virtually all beverage types tested, with concentrations ranging widely and particles originating from water sources, packaging materials, and processing surfaces. The findings raise concerns about ongoing low-level human exposure through everyday drinks.
Every Sip Counts: Microplastics in Drinking Water
AI summary Read the abstract
This paper describes the first planned study to examine microplastics in drinking water sourced in New Zealand, including bottled water. It explains that plastics used in water storage and supply can break down into tiny particles called microplastics, and outlines why testing drinking water for these particles matters.
Quantifying Nanoplastics and Microplastics in Food and Beverages Using Pyrolysis-Gas Chromatography–Mass Spectrometry: Challenges and Implications
AI summary Read the abstract
Scientists used a specialized analytical technique to measure nanoplastics and microplastics in common Australian foods and beverages, estimating that people consume about 1.7 to 2.0 milligrams of plastic per year from drinks like water, tea, coffee, beer, and wine alone. The study also highlighted that current detection methods may undercount plastic contamination in solid foods because of measurement limitations.
Determination of microparticles, in particular microplastics in beverages

This study reviewed and tested methods for detecting microparticles including microplastics in beverages, addressing a gap in food safety monitoring. The research is relevant to understanding human exposure to microplastics through drinking water and packaged beverages.
Synthetic microplastics in hot and cold beverages from the UK market: Comprehensive assessment of human exposure via total beverage intake
AI summary Read the abstract
Researchers tested 155 common hot and cold beverages from UK stores and found microplastics in every single sample. Hot tea had the highest levels at about 60 particles per liter, and hot beverages consistently contained more microplastics than cold ones, suggesting that heat causes more plastic to leach from packaging. Based on typical UK drinking habits, the estimated daily microplastic intake from beverages alone was 3,432 to 6,864 particles per person.
