The distribution and cycling of mercury species in the western Mediterranean
Total mercury concentrations were determined in water samples from ten vertical profiles in the western Mediterranean. Most Hg concentrations ranged from 0.5 pM to 4 pM, with a geometric mean of 2.26 pM. Such concentrations are in the same range as those measured in the North Atlantic and equatorial Pacific waters. Additional measurements of reactive mercury and gaseous species (elemental mercury and dymethylmercury) were performed in the Alboran Sea and the Strait of Gibraltar. The mass balance budget in the western Mediterranean shows that, while the total mercury exchanges at the straits are not unbalanced, mercury enters the Mediterranean as inorganic mercury and is exported to the Atlantic Ocean partially as methylated species.
