Abstract The growth of global plastic production and the associated increase in microplastic pollution environment has attracted increasing attention from both scientists general public. Drinking water public supply systems is essential for human life therefore ensuring its high quality a priority. aim this study was to detect identify microplastics drinking systems. Water samples were collected various locations across Czech Republic during two sampling campaigns 2021 2023. A total 58 580 particles analyzed using μ-FTIR (micro-Fourier-transform infrared spectroscopy). These categorized by material, shape, color, quantity. Of particles, 196 identified as microplastics. Except one sample, where no detected, concentration ranged 20 180 per liter first campaign 120 second campaign. In campaign, fibers transparent predominantly while collection, fragments blue more common. most frequently observed materials paper with polyethylene coating, terephthalate (PET), polyester (PES). This also provides data on average daily intake via water, calculated 2 2.1 MP/kg/day, all results undergoing statistical evaluation. Furthermore, addresses new European legislation proposed standardized methodology, which represents significant step toward achieving consistent studies and, upon adoption, will likely influence direction research water. However, discussed study, methodology contains several problematic aspects, are elaborated upon. With planned inclusion EU list substances be monitored, it continue collect data. confirms presence detailed information their characteristics supplied Republic. Highlights Two carried out. Microplastics found 57 out samples. MP concentrations amounted 68.3 65 MP/L. Material, color detected identified. Average MP/kg/day. Graphical abstract
