20.500.12556/RUL-169137 Revealing future aquatic environmental challenges preservice chemistry teachers’ study on adsorption of endocrine disruptors on microplastics Water resources are subject to an increasing number of different types of pollutants, chemical and physical, which can interact in different ways. Among these, microplastic particles (MPs) and pharmaceuticals often coexist, with MPs serving as potential carriers for them. This interaction poses dual risks, including physical harm and chemical intoxication upon ingestion, since MPs prolong their presence in aquatic ecosystems and organisms. Besides, both microplastics (MPs) and pharmaceuticals cannot be completely removed by current wastewater treatment technologies and are prone to cycle in the hydrosphere. To address these concerns, an inquiry-based laboratory module was implemented in a Fundamentals of Environmental Chemistry course to engage preservice chemistry teachers in investigating the adsorption of pharmaceuticals onto MPs. A total of 21 students, working in groups of 2−3, participated in two iterations of the 3 h module, which aimed to address water pollution challenges. Students identified research questions, formulated hypotheses, and designed experimental plans to assess the adsorption of drospirenone and diclofenac on four MP types: polyethylene (PE), polystyrene (PS), polyethylene terephthalate (PET), and poly(butylene adipate) terephthalate (PBAT). The pharmaceuticals’ concentrations were analyzed pre- and postexperiment using UV−vis spectrophotometry. Results indicated a higher adsorption of diclofenac compared with drospirenone, with PBAT showing superior adsorption capacity for both pharmaceuticals. One-way ANOVA identified significant differences in adsorption among MPs, particularly between PBAT and other types of MPs. Students’ environmental competencies improved after the activity, as suggested by pre- and postquestionnaire comparisons. upper-division undergraduate environmental chemistry laboratory instruction hands-on learning inquiry-based learning drugs/pharmaceuticals microplastics UV−vis spectroscopy okoljske spremembe mikroplastika true false true Angleški jezik Slovenski jezik Članek v reviji 2025-05-14 09:04:52 2025-05-14 09:04:52 2026-01-20 14:23:10 0000-00-00 00:00:00 2025 0 0 Str 2112-2119 no. 5 Vol. 102 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-01-01 54 1938-1328 10.1021/acs.jchemed.5c00025 233997571 vinko-et-al-2025-revealing-future-aquatic-environmental-challenges-preservice-chemistry-teachers-study-on-adsorption-of.pdf vinko-et-al-2025-revealing-future-aquatic-environmental-challenges-preservice-chemistry-teachers-study-on-adsorption-of.pdf 1 C6EAA636D4762F5DC0AB8ECE3046FA2E f8413138f0377e7eb401788977aa2b069339c87463dada7a9dde9685dd71f4a8 f104def0-3090-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210317 https://pubs.acs.org/doi/10.1021/acs.jchemed.5c00025 1 f1781b4d-f602-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225748 Zdravstvena fakulteta Pedagoška fakulteta 0 0 0
