20.500.12556/RUL-139592 Effects of microplastics from disposable medical masks on terrestrial invertebrates This study investigated impacts of microplastics from disposable polypropylene medical masks on woodlice Porcellio scaber, mealworm larvae Tenebrio molitor and enchytraeids Enchytraeus crypticus. Effects of microplastics on survival, reproduction, immune parameters and energy-related traits were assessed after 21 days exposure in soil. Microplastics obtained from each medical mask layer separately differed in size and shape (inner frontal layer: 45.1 ± 21.5 µm, fibers; middle filtering layer: 55.6 ± 28.5 µm, fragments; outer layer: 42.0 ± 17.8 µm, fibers) and composition of additives. Overall, the concentrations of metals and organic chemicals were too low to cause effects on soil invertebrates. The microplastics from disposable medical masks at 0.06%, 0.5%, 1.5%, w/w did not induce severe adverse effects on survival or reproduction (for enchytraeids). A transient immune response of woodlice and a change in energy-related traits in mealworms were observed, which was most clearly seen for the microplastics from the outer layer. This was reflected in increased electron transfer system activity of mealworms and different immune response dynamics of woodlice. In conclusion, the tested soil invertebrates respond to microplastics from disposable medical masks, but it remains unclear what these changes mean for their fitness on the long term. immune response energy related traits reproduction additives kopenski nevretenčarji medicinske maske mikroplastika true false true Angleški jezik Slovenski jezik Članek v reviji 2022-09-05 12:57:29 2022-09-05 12:57:30 2022-09-16 04:11:18 0000-00-00 00:00:00 2022 0 0 9 str. art. 129440 Vol. 438 15 Sep. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 591 0304-3894 10.1016/j.jhazmat.2022.129440 113941763 1-s2.0-S030438942201233X-main.pdf 1-s2.0-S030438942201233X-main.pdf 1 D6611876EFFBC2CB008EBF672091DE81 a9712a4ca46ba52580e7d758c37128a76c70e157047b5708aa13ff447f561de4 fa493a7f-2d09-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=160175 https://www.sciencedirect.com/science/article/pii/S030438942201233X 0 ace151e7-2d09-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=160173 Biotehniška fakulteta Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
