Figure 4. Antioxidant enzymes activity (mean ± STD) of: (A) and (B) SOD; (C) and (D) CAT; and (E) and (F) G6PDH, respectively in gills and digestive glands from unexposed (CT) and mask leachate-exposed mussels, after 14 days of bioassay. Asterisks indicate significant differences between control and mask leachate-exposed mussels (t-test; P < 0.05). CAT: Catalase; G6PDH: glucose-6-phosphate dehydrogenase; SOD: superoxide dismutase.
