title: Mercury concentrations in South Atlantic swordfish, Xiphias gladius, caught off the coast of Brazil.
abstract: This study evaluated the concentrations of mercury in fillets (anterior, middle, and end regions) from the swordfish, Xiphias gladius, and the relationships between mercury concentration and fish weight, as well as the region of collection. Of a total of 697 swordfish analyzed, 11 had mercury concentrations above 1 mg/kg, 421 were between 0.5 and 1.0 mg/kg, and 265 were below 0.5 mg/kg. The anterior and posterior regions had greater concentrations of mercury than the middle region, and fish caught off the northern coast of Brazil had a higher concentration than those caught off the southern coast.
