“…aggravated in consecutive generations(Barata et al 2016;Campos et al 2016). According toLambert et al (2021), signi cant delays in the rst offspring and reduction in the total number of neonates of D. magna were observed after exposure to BP-3 (166 µg/L) in a traditional chronic 21d trial. The same signi cant effects were not observed after exposure to EHMC (75 µg/L) by these authors.…”

Organic ultraviolet (UV) lters have often been detected in aquatic ecosystems in concentrations ranging from ng/L to μg/L. However, both their acute and chronic effects on aquatic organisms have been insu ciently explored. This study aimed to rstly evaluate acute toxicity of some of the main UV lters used worldwide (2-ethylhexyl,4-methoxycinnamate/EHMC, avobenzone/AVO, benzophenone-3/BP-3, and octocrylene/OC), in three aquatic organisms (Artemia salina, Desmodesmus subspicatus, and Daphnia magna), to further investigate multigenerational effects in D. magna. After con rming the acute toxicity, D. magna individuals were chronically exposed to environmentally relevant concentrations of UV lters for two consecutive generations (F0 and F1), and reproductive endpoints, as well as catalase (CAT) and glutathione-S-transferase (GST) activities, were assessed. EHMC showed the most toxic potential, with the lowest EC 50 values for the three organisms. On the other hand, reproductive delays and a decrease in the reproduction rate were observed in the F1 generation exposed to AVO (4.4 µg/L), BP-3 (0.17 µg/L), EHMC (0.2 µg/L), and MIX. An increase of the CAT activity in organisms exposed to BP-3 and EHMC suggested induction of the antioxidant system. Although no reproductive effect was observed in the rst generation, toxic effects obtained in the F1 revealed the importance of multigenerational studies and the potential harm of UV lters to the life cycle of D. magna, even at environmentally relevant concentrations. This emphasizes the need for further studies considering these levels of exposure and more realistic experimental designs to better understand their potential risks.
