| Sumario: | Cadmium, copper, iron, manganese, nickel and zinc concentrations were determined by atomic absorption spectrophotometry in samples of soft tissues of the mussel Mytilus galloprovincialis (Lamarck, 1819), collected from 19 sampling points on the Algarve Coast (southern Portugal). Of all the sampling points, Portimão showed the highest metal concentrations in mussel tissues. Metal concentrations increased near urban centres and sources of industrial effluents. Consequently, the areas influenced by the Arade River, the Guadiana estuary and the Formosa Ria lagoon presented the highest metal concentrations. Metal concentrations in mussels from the west coast of the Algarve were higher than in those from the east coast. Our findings indicate that Cd and Cu concentrations in mussels from the different sampling points have increased over the last 10 years, while Fe, Mn and Ni concentrations along the Algarve Coast have fallen. These results are discussed in relation to the variation of human impact, some environmental factors, and other natural phenomena. |
