The results are equivalent or lower than levels reported in ichthyofauna worldwide. Certain values of muscular Cd, Hg, Pb and Zn were, however, above thresholds for human consumption. Levels varied among tissues, species and fish length, but were seldom influenced by the nutritional condition of the fish, its gender and its reproductive status. Correlations between hepatic Hg and Se levels in Swordfish (r(2) = 0.747) and Yellowfin Tunas (r(2) = 0.226), and among metallothionein linking metals imply the existence of detoxification processes in these species. Level differences between fish from the Mozambique Channel and Reunion Island reflect differences of diets rather than differences of elemental availability in both environments. specialized metals fish contamination detoxification guidelines 038 146 2 548-566 2007 0269-7491 https://www.documentation.ird.fr/hor/fdi:010037917 10.1016/j.envpol.2006.07.015 0269-7491 [F B010037917] https://www.documentation.ird.fr/hor/fdi:010037917 https://www.documentation.ird.fr/intranet/publi/2007/05/010037917.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2007-06-01 2017-08-23 fdi:010037917 fre
