Sharks are sensitive to the
presence of Hg, as they are considered long-lived organisms (Lyle,
1984). Pelletier (1995) suggested that the bioaccumulation of Hg
is a result of multiple factors, including environmental factors
such as habitat and season, biological factors, such as excretory mechanisms,
low growth rates and trophic level, and anthropogenic factors
such as overfishing. The complex interactions between these factors
also help determine the content of Hg in each organism or species
