Resumen : | We analyzed total mercury and selenium bioaccumulation in muscle tissue and cartilage fibers (fins) from smooth hammerhead shark, Sphyrna zygaena, caught off Baja California Sur, Mexico. In muscle tissue, the mercury concentration ranged from 0.005 to 1.93 μg g−1 ww (wet weight), which falls within the safety limits for food set by international agencies (Hg > 1.0 μg g−1 ww). Only one specimen showed a mercury value that exceeded this limit. In fins, the mercury bioaccumulation was lower (<0.05). Selenium in muscle ranged from 0.11 to 1.63 μg g−1 ww, while in fins it ranged from 0.13 to 0.56 μg g−1 ww. |
