20.500.12556/RUL-168407 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 butts cigarette filters microfibers crustaceans insects rotifers Daphnia metals bioplastic Rotifera cigaretni ogorki cigaretni filtri mikrovlakna raki žuželke kotačniki true false true Angleški jezik Slovenski jezik Članek v reviji 2025-04-11 12:58:45 2025-04-11 12:58:46 2025-04-12 04:11:17 0000-00-00 00:00:00 2025 0 0 11 str. art. 126199 Vol. 374 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 592 1873-6424 10.1016/j.envpol.2025.126199 232114947 1-s2.0-S026974912500572X-main.pdf 1-s2.0-S026974912500572X-main.pdf 1 426215A43D169AFD988AEBA09095E3AD 7e17aa2e394b8ff799a764da7e07b45ec4c4e898c1693a0f117b46322f625248 16bf4618-16c3-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201806 https://www.sciencedirect.com/science/article/pii/S026974912500572X 0 06b09ff9-16c3-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201804 Biotehniška fakulteta Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
