20.500.12556/DiRROS-22201 Microplastics from cigarette filters comparative effects on selected terrestrial and aquatic invertebrates Cigarette filters comprise plasticised cellulose acetate, a synthetic polymer categorized as bioplastic. They represent a significant source of microplastics (MPs), in particular microfibers, and associated chemicals, yet their impact on organisms, especially soil invertebrates, is not well-studied. This research examines the effects of MPs milled from smoked (SCF-MPs) and unsmoked cigarette filters (UCF-MPs) on terrestrial invertebrates (Porcellio scaber, Tenebrio molitor) and aquatic invertebrates (Daphnia magna, Brachionus calyciflorus). SCF-MPs and UCF-MPs were found to be 9.06 ± 4.1 μm and 12.71 ± 6.82 μm in size, respectively. Both samples contained triacetin and potentially toxic metals, while SCF-MPs also contained nicotine and a larger number of trace organic compounds. While exposure to SCF-MPs or UCF-MPs (up to 1.5 % MPs, w/w in soil) did not affect the survival of either terrestrial invertebrate, several physiological responses were observed. These included changes in immune parameters, energy-related biomarker levels, and altered glutathione S-transferase and acetylcholinesterase activities. Both types of MPs were acutely toxic to aquatic invertebrates, reducing the survival rates of B. calyciflorus (10 mg L−1 of either particle after 48h exposure) and D. magna (100 mg L−1 of SCF-MPs after 48h exposure). SCF-MPs generally caused more pronounced effects than UCF-MPs. This study highlights the need for effective environmental management to address both smoked and unsmoked cigarette filters. cigarette buts cigarette filters microfibers crustaceans insects rotifers cigaretni ogorki cigaretni filtri mikrovlakna raki žuželke kotačniki true false true Elsevier Angleški jezik Slovenski jezik © 2025 The Authors Neznano 2025-05-09 08:05:03 2025-05-09 08:12:51 2025-10-24 03:50:48 0000-00-00 00:00:00 2025 0 0 str. 1-11 [article no.] 126199 Vol. 374 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-04-02 592 1873-6424 10.1016/j.envpol.2025.126199 232114947 1-s2.0-S026974912500572X-main.pdf 1-s2.0-S026974912500572X-main.pdf 1 7B97EA326E587AEA464B6656BD723863 96b2ff6ab5b6aa08293fd05e4efdd1dfe43559b99255a7642d562d9531156c89 8b32386d-2c9c-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=32133 https://doi.org/10.1016/j.envpol.2025.126199 0 6def834b-2c9c-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=32132 RAZ_Dolar_Andraz_2025.docx RAZ_Dolar_Andraz_2025.docx 1 48035506DE746F483CAB095330081FEB 0551eeefeae860971d66126a5bc6a74689b39fedd9e40517b6ea2756e5aa3124 9fd9f257-2c9c-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=32134 Zavod za gradbeništvo Slovenije 0 0 0
