Resumen:
Concentration of essential (Se, Zn and Cu) and non-essential (As, Cd, Hg
and Pb) trace elements were measured in selected tissues of two dead
whale sharks (Rhincodon typus) stranded in the Gulf of California (GC)
in 2017 and 2018. Concentrations of Cd and Pb in the skeletal muscle of
the whale shark from La Paz Bay, GC were higher compared to a previous
study on whale shark from China. The shark from La Paz Bay also
presented higher concentration of Pb in the epidermis, compared to the
same tissue of the other whale shark stranded in Punta Bufeo, GC. The Hg
in all analysed tissues was lower than those documented in carnivorous
sharks. Molar ratio Se:Hg shows an excess of Se over Hg in all the
tissues sampled in both sharks.
