Profenofos (PFF) is an organophosphorus pesticide frequently detected in surface waters, soil habitats, and even biota. Some studies have demonstrated the potential risks of PFF to aquatic organisms. However, most of these studies were focused on its acute rather than chronic impacts, and the subjects are usually large vertebrates. Here, we treated D. magna (< 24 h) with PFF at doses of 0, 0.07, 0.28, and 1.12 mg/L for 21 days to study its long-term toxic impacts. Exposure to PFF largely decreased the survival rate and inhibited the growth and reproduction of D. magna. Then, PCR arrays were used to evaluate the changes in the expression of 13 genes related to growth, reproduction, and swimming behavior. The results revealed that the expression of several genes was dramatically changed by exposure to each dose of PFF, which might be responsible for the observed toxic effects of PFF. In summary, our findings imply that long-term PFF exposure can be highly hazardous to the growth, development, and reproduction of D. magna. © 2023.
