| contents | Fe, Zn, Cu and Cd concentrations in the digestive gland and muscle tissues of Octopus vulgaris and Sepia officinalis from two coastal areas in Portugal Joana Raimundo Patrícia Pereira Carlos Vale Miguel Caetano Ciencias de la Tierra metals Portugal cephalopods digestive gland Concentrations of Fe, Zn, Cu and Cd were measured in the mantle, arm and digestive gland of Octopus vulgaris (Cuvier,1797) and in the mantle and digestive gland of Sepia officinalis (Linnaeus, 1758) captured at two sites on the Portuguese coastduring 2001. The most abundant element was Zn, reaching 121 µg g1 in muscle tissues; Fe and Cu presented a similar range ofconcentration, 5.481 µg g1 and 3.372 µg g1, respectively; and Cd varied between 0.010 and 3.3 µg g1. Metal concentrationsin the digestive gland were two and three orders of magnitude higher than those recorded in the mantle and arm. The relationshipbetween metal concentration and body weight was found mainly in the digestive gland and rarely in the mantle and arm. TheCd:Zn and Cd:Cu ratios were particularly high in the digestive gland of the two species captured at the most contaminated siteand presented positive linear relationships with the body weight. This suggests a progressive accumulation of Cd in the digestivegland of octopus and cuttlefish with growth, in comparison to the essential elements Zn and Cu. 2005 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48003111 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.1B Vol.31 |
