20.500.12556/DiRROS-24314 Sampling and identification of microplastics in groundwater Microplastics pollution in groundwater remains significantly underreported within scientific literature. This paper presents a comprehensive protocol outlining the methodology for the sampling of groundwater from boreholes, as well as the steps of microplastics separation and analysis. It provides an extensive description of a filtration sampling system designed specifically for this purpose, along with the detailed sampling procedure. In addition, it presents the laboratory analysis of microplastic particles, including their characterization based on size, shape, color, transparency, and chemical structure using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and micro-FTIR spectroscopy. Factors that can influence results are discussed, and special attention is paid to preventing contamination of samples. The methodology described also considers the requirements of the Annex of Commission Delegated Decision (EU) 2024/1441 of 11 March 2024, supplementing Directive (EU) 2020/2184 of the European Parliament and of the Council. This comprehensive written protocol, accompanied by video guidance, is intended to support the development of a synchronized methodology for monitoring microplastics in groundwater or drinking water. This resource will be of interest to researchers in the field of microplastics worldwide. microplastics groundwater spectroscopic methods pollution mikroplastika podtalnica spektroskopske metode onesnaženje true false true Angleški jezik Slovenski jezik Neznano 2025-11-26 09:17:49 2025-11-26 09:17:49 2025-11-27 03:58:54 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 20. 11. 2025; str. 1-19 [art. no.] ǂe68652 Vol. 225 Nov. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-11-07 556.3 1940-087X 10.3791/68652 257986563 https://dx.doi.org/10.3791/68652-v 1 68fa73b7-caa0-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=36214 RAZ_Kovac_Virsek_Manca_2025.pdf RAZ_Kovac_Virsek_Manca_2025.pdf 1 5929888F7A1976E2254CA20F8C1CAF29 c37673e70c3049ba4989095cfa8a6d72203900a0587799bfffff87011f0aac4c 7ed15a3f-caa0-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=36215 Nacionalni inštitut za biologijo 0 0 0
