20.500.12556/RUL-137659 The first plastic produced, but the latest studied in microplastics research the assessment of leaching, ecotoxicity and bioadhesion of Bakelite microplastics Bakelite, the first synthetic plastic, is a rather unexplored material in the field of ecotoxicology, despite its long production and use. The aim of this study was to investigate the ecotoxicity of Bakelite microplastics (before and after leaching) and its leachates on four aquatic organisms: the crustacean Daphnia magna, the plant Lemna minor, the bacterium Allivibrio fischeri and the alga Pseudokirchneriella subcapitata. Bakelite microplastics before and after leaching and leachates affected all organisms, but to varying degrees. Leachates showed increased ecotoxicity to Daphnia magna, while Pseudokirchneriella subcapitata was more affected by particles. For Lemna minor and Allivibrio fischeri, the effects of particles before leaching and leachate were comparable, while the negative effect of particles after leaching was minimal or not present. All leachates were analysed, and phenol and phenol-like compounds were the predominant organics found. In addition, bioadhesion of Bakelite microplastics to the surface of Daphnia magna and Lemna minor was confirmed, but the particles were mainly weakly adhered. Results of this study suggest that, in addition to the recently studied microplastics from consumer products (e.g. from polyethylene and polystyrene), microplastics from industrial plastics such as Bakelite may be of increasing concern, primarily due to leaching of toxic chemicals. microplastics Bakelite aquatic toxicity adsorption bioadhesion leachate mikroplastika bakelit strupenost adsorpcija bioadhezija izcedne vode true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-24 09:08:13 2022-06-24 09:08:14 2022-09-15 04:15:37 0000-00-00 00:00:00 2022 0 0 8 str. art. 119454 Vol. 307 15 Aug. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 504.5:678 0269-7491 10.1016/j.envpol.2022.119454 108913667 1-s2.0-S0269749122006686-main.pdf 1-s2.0-S0269749122006686-main.pdf 1 4AA328785604818106A4B3BB66D28AED dc86920c97fbda441d712450acb2dc82d757f2582ff0219a6bfef443bfc2120d 1a0aba89-f38e-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157695 https://www.sciencedirect.com/science/article/pii/S0269749122006686 1 38230fa7-f38c-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157694 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
