In this study, the chronic effects of 2 BZT-UVs, 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl)phenol (UV-234) and 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328) were evaluated for each compound alone and in a mixture on the freshwater green algae Chlamydomonas reinhardtii and the freshwater crustacean Daphnia magna. Life-history endpoints (viability, reproduction, and growth) and oxidative stress–related biomarkers (gene transcription, reactive oxygen species [ROS] production, and lipid peroxidation) were measured. Results have been published in a peer-reviewed scientific article. Citation: M. Giraudo, G. Cottin, M. Esperanza, P. Gagnon, A.O. De SIlva, M. Houde. 2017.
