Mercury and Selenium in a Top-Predator Fish, Trichiurus lepturus (Linnaeus, 1758), from the Tropical Brazilian Coast, Rio de Janeiro

Muscular mercury and selenium were assessed in a voracious fish from three Brazilian coastal areas with different environmental conditions. Mercury was higher in specimens from Ilha Grande Bay (0.35 ± 0.17 μg g −1 ) than in cutlassfish from Guanabara Bay (0.30 ± 0.15 μg g −1 ) and Buzios coast (0.13...

More Information
Summary:Muscular mercury and selenium were assessed in a voracious fish from three Brazilian coastal areas with different environmental conditions. Mercury was higher in specimens from Ilha Grande Bay (0.35 ± 0.17 μg g −1 ) than in cutlassfish from Guanabara Bay (0.30 ± 0.15 μg g −1 ) and Buzios coast (0.13 ± 0.08 μg g −1 ), respectively. No difference was found regarding selenium among these areas. Mercury was positively correlated with fish length and size intervals (sub-adult, small and large adult), suggesting that larger and older fish bioaccumulated more mercury. A large excess of molar selenium in relation to mercury was observed.
