The trace element concentrations found in muscle, liver and kidney
samples of mako sharks are summarized in Table 1. There were
no significant differences among tissues for either Pb (p = 0.10) or
As (p = 0.43) concentrations. Cd concentration was lower in muscle
than in liver (p = 0.04) and kidney (p = 0.0007) samples. Hg concentration
in muscle was higher than in liver (p b 0.001) and kidney
(p b 0.001) samples.
