Abstract Microplastic (MP) ( 25 μm) using focal plane array-based micro-Fourier transform infrared microscopy imaging. Two forms (fibers and fragments) and 11 types of MPs (polypropylene, polystyrene, polyethylene, polyethylene terephthalate, polyurethane, polyvinyl chloride, polyamide, polyacrylic acid, polyacrylamide, polyethylene vinyl acetate, and cellulose) with sizes of 0.025–5.000 mm and abundances ranging from 2 particles/bottle to 23 particles/bottle were identified. Based on this investigation, MP contamination may originate from the raw water source and flakes from the packaging. The estimated daily intakes for adults and children were expected to be 0.274 M P/(kg·d) and 0.600 M P/(kg·d), respectively. These findings will help to achieve a full and proper assessment of MPs in drinking water in China.
