Abstract
Portman Bay presents elevated quantities of metals and heavy metals in the sediments and rocky outcrops. The calcitic skeletons of the sea u rchins that live there present elevated concentrations of Mn, Fe, Zn, and Pb (249, 273, 32, and 59 ppm) in comparison with control zones (be ach of La Vila) where the concentrations for these elements are 5, 7, 8, and 2 ppm, respectively. Two species of sea urchins have been studi ed: Paracentrotus lividus and Arbacia lixula. The different compositio ns between the plates and the spines of their skeletons have also been studied.
