Effects of exposure to polystyrene microbeads of different diameters (0.05, 0.5, and 6 μm) on P. nana: (A) growth rate, (B) fecundity. Copepods were exposed to microbeads (0.1, 1, 10, and 20 μg/mL) for 24 h. The black bar (N-C) indicates the time taken from nauplius to copepodid stage, whereas the grey bar (N-A) shows the time from nauplius to adult stage. Differences between groups were analyzed for significance using Tukey’s multiple comparison test. Different letters above columns indicate significant differences (P < 0.05).
