Abstract (EN): The concentrations of metals were determined in northwest (NW) coast of Portugal seawaters and soft tissues of goose barnacles Pollicipes pollicipes. P. pollicipes can be used for monitoring metal contamination in these coastal seawaters, because there were significant correlations (p < 0.05) for all metals between soft tissues and seawaters during the four seasons. Metal concentrations in seawaters and P. pollicipes had significant (p < 0.05) spatial and seasonal variations and mean log BAFs for Fe and Cd were higher than for Cr, Cu, Mn and Zn. Regarding the metal concentrations obtained in the coastal seawaters, all NW coast of Portugal should be classified as "Class IV - Bad", except two locations (location 7 at Summer and location 10 at Winter), which should be classified as "Class III - Moderate". However, considering the metal concentrations bioaccumulated in P. pollicipes, all locations should be classified as "Class III - Remarkably Polluted" during all seasons of 2011.
