20.500.12556/RUL-160102 Response of terrestrial crustacean Porcellio scaber and mealworm Tenebrio molitor to non-degradable and biodegradable fossil-based mulching film microplastics Agricultural mulching films are potential sources of microplastics (MPs) in soil. As an alternative to conventional non-degradable mulching films, a variety of different biodegradable mulching films are used. However, it is not yet known whether MPs from biodegradable mulching films pose a lower risk to terrestrial invertebrates compared to MPs from conventional mulching films. In this study, the effects of MPs produced from two conventional polyethylene (PE-1 and PE-2) and two biodegradable (starch-based poly(butylene adipate coterephthalate); PBAT-BD-1, and PBAT-BD-2) fossil-based mulching films on terrestrial crustacean woodlice Porcellio scaber and mealworm Tenebrio molitor were compared. A key finding was that no clear differences in induced responses between biodegradable and conventional MPs were detected. No adverse effects on P. scaber after two weeks and on T. molitor after four weeks of exposure were observed up to 5 % (w/w dry soil) of either MP type. However, some sublethal physiological changes in metabolic rate and immune parameters were found in P. scaber after two weeks of exposure indicating a response of organisms to the presence of MP exposure in soil. In addition, it was demonstrated that both types of MPs might affect the soil water holding capacity and pH. In conclusion, we confirmed that biodegradable MPs can induce responses in organisms hence further studies testing the environmental hazard of biodegradable MPs are justified. mealworms isopods immune response microplastics agriculture LDPE PBAT polyethylene development woodlice mokarji enakonožci imunski odgovor mikroplastika true false true Angleški jezik Slovenski jezik Članek v reviji 2024-08-20 15:04:49 2024-08-20 15:04:50 2024-08-28 12:44:05 0000-00-00 00:00:00 2024 0 0 12 str. art. 175379 Vol. 951 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 504 1879-1026 10.1016/j.scitotenv.2024.175379 204627459 1-s2.0-S0048969724055293-main.pdf 1-s2.0-S0048969724055293-main.pdf 1 FA25CA8B9BE79E942BD55942127BC618 dfa4b0ecdf7400cc1b94ae0604a39a64feda6b656d53b35d227a1b4d6d7293b6 21efb932-5ef5-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188572 https://www.sciencedirect.com/science/article/pii/S0048969724055293 0 f3f00d9f-5ef4-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188571 Biotehniška fakulteta Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
