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

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

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 coast during 2001. The most abundant element was Zn, reachin...

The most abundant element was Zn, reaching 121 µg g–1 in muscle tissues; Fe and Cu presented a similar range of concentration, 5.4–81 µg g–1 and 3.3–72 µg g–1, respectively; and Cd varied between 0.010 and 3.3 µg g–1. Metal concentrations in the digestive gland were two and three orders of magnitude higher than those recorded in the mantle and arm. The relationship between metal concentration and body weight was found mainly in the digestive gland and rarely in the mantle and arm. The Cd:Zn and Cd:Cu ratios were particularly high in the digestive gland of the two species captured at the most contaminated site and presented positive linear relationships with the body weight. This suggests a progressive accumulation of Cd in the digestive gland of octopus and cuttlefish with growth, in comparison to the essential elements Zn and Cu. Se midieron las concentraciones de Fe, Zn, Cu y Cd en el manto, el brazo y la glándula digestiva de Octopus vulgaris (Cuvier, 1797) y en el manto y la glándula digestiva de Sepia officinalis (Linnaeus, 1758), capturados en dos zonas de la costa portuguesa durante 2001. El elemento más abundante fue Zn, alcanzando 121 µg g–1 en los tejidos musculares; Fe y Cu presentaron un intervalo de concentración similar, 5.4–81 µg g–1 y 3.3–72 µg g–1, respectivamente; y Cd varió entre 0.010 y 3.3 µg g–1. Las concentraciones de metales en la glándula digestiva fueron dos y tres órdenes de magnitud superiores que los registrados en el manto y brazo. La relación entre la concentración de metal y el peso corporal se encontró principalmente con la glándula digestiva y raramente con el manto y brazo. Las razones Cd:Zn y Cd:Cu fueron particularmente altas para la glándula digestiva de las dos especies capturadas en la zona más contaminada y presentaron una relación lineal con el peso corporal. Esto sugiere una acumulación progresiva de Cd en las glándulas digestivas del pulpo y la sepia con el crecimiento, en comparación con los elementos esenciales Zn y Cu.
