Transcriptional and Biochemical Effects of Cadmium and Manganese on the Defense System of Octopus vulgaris Paralarvae

Figure 6

Catalase activity in O. vulgaris paralarvae exposed to cadmium (a) and manganese (b). Paralarvae were treated with 0 (control), 10, and 100 μg/L CdCl₂ or 10, 100, and 1000 μg/L MnCl₂ for 24 hours. All data are represented as mean ± SD (30 paralarvae per treatment). Asterisks indicate statistically significant differences versus nonexposed controls at .
