A Reassessment of Trace Metal Budgets in the Western Mediterranean Sea

摘要

This paper presents inputs and output fluxes of dissolved metals (As, Cd, Co, Cu, Fe, Mn, Ni, Pb and Zn) into and out the Western Mediterranean. These flux estimates are based on the most recently published concentrations and fluxes for the atmosphere, the rivers and the straits. Comparison of the different sources shows the predomi- Nance of the inputs through the straits over other sources. The river input is smaller than the atmospheric input ex- Cept for As. For all elements except Fe, output flux and Input flux are balanced; iron budget indicates transfer From the dissolved to the particulate phase.
