Figure 5: Effects of exposure to polystyrene microbeads of different diameters (0.05, 0.5, and 6 μm) on antioxidant-related enzymes.

From: Adverse effects of microplastics and oxidative stress-induced MAPK/Nrf2 pathway-mediated defense mechanisms in the marine copepod Paracyclopina nana

Figure 5

All polystyrene microbeads were used at 20 μg/ml. Enzymatic activity is presented as % of controls. Different letters above columns indicate significant differences, defined as P < 0.05.
