Aquatic species are exposed to several long-chain per- and polyfluoroalkyl substances (PFASs) in the environment but their potential toxicity is not well studied. In this study, we assessed the effects of perfluoroundecanoic acid (PFUnDA) exposure on developing zebrafish. To do this, we investigated the potential for oxidative stress and neurotoxicity by measuring reactive oxygen species, apoptosis, gene expression, and locomotor activity. Mortality was evident in fish exposed to 1000 µg/L PFUnDA, and apoptosis was indicated in fish exposed to 100 µg/L PFUnDA via an increase in Show less
