The dataset was created by Niu et al. based on the microalgal growth inhibition experiments (during 2021 and 2022) and chemical analysis (during 2023) at the Flanders Marine Institute (VLIZ) and Ghent University, Belgium.&nbsp;</p>","EngDescr":"<p>The goal of our work was to assess the ecotoxicological effects of plastic leachates from pristine and weathered items on a marine diatom. To do so, we exposed the marine diatom <i>Phaeodactylum tricornutum</i> to the leachates from pristine and UV-weathered self-reinforced (SR-) polylactic acid (PLA) and polypropylene (PP) items. As a positive control, we assessed the response of the diatom growth to two associated compounds (dedecan-1-ol and 2,4- di-tert-butylphenol), components of the tested items. Weathered plastic items were obtained after being exposed to 57-day artificial ultraviolet radiation, simulating 18-months of solar exposure in central Europe. Our results indicate that neither leachates from pristine nor weathered SR-PLA items had adverse effects on <i>P. tricornutum</i> growth. This outcome was corroborated by the measured concentrations of associated compounds (i.e. dodecan-1-ol) in leachates, which were at least three orders of magnitude lower than the 72-h EC50 of diatom growth (dodecan-1-ol: 1.56 mg / L, 2,4,-DTBP: 1.52 mg / L). Leachates from weathered SR-PP items at full-strength concentration induced 51% greater growth inhibition than control treatments, and 43% greater inhibition than leachates from pristine SR-PP items at the same concentration. Our results suggest that leachates from the tested weathered SR-PP items inhibited the population growth of <i>P. tricornutum</i>, although at plastic concentrations above environmentally relevant levels.&nbsp;</p>","OrigAbstract":null,"OrigDescr":null,"Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":null,"EmbargoDate":"2025-10-14","OrigDescrLangNL":null,"OrigLangCode":null,"OrigLangCodeExtended":null,"OrigLangID":null,"DescrCompFlag":null,"DescrTransFlag":null,"Citation":"Niu, Z.; Segura, S.A.; Le Gall, M.; Curto, M.; Demeyer, E.; Asselman, J.; Janssen, C.R.; Dhakal, H.N.; Davies, P.; Everaert, G.; Catarino A.I.; Flanders Marine Institute; Blue Growth Research Lab; Institut Français de Recherche pour l'Exploitation de la Mer; University of Portsmouth; Centexbel; (2025): Raw data of the manuscript \"Leachates from Weathered Polypropylene Items, But Not from Polylactic Acid, Induce Ecotoxicological Effects on a Marine Diatom”.
