Contaminación por metales pesados en los sedimentos marinos de la plataforma costera mediterránea
[EN] Heavy metals concentration (Hg, Pb, Cd, V and Ni) in sediments from the spanish mediterranean continental shelf was analyzed. Relative low levels of these microcontaminants were found in all studied zones, but some areas showed high values (Besós, Llobregat, Ebro, Valencia and Cartagena). A clear correlation exists bet-ween the use of the river basin and the levels of heavy metals present in sediments. It is also important the influence of general dynamics of the ecosystem in spill-zones of contaminants. [...]
[ES] Los metales pesados han sido ampliamente estudiados en función de su toxicidad frente a los seres vivos. Es suficientemente conocida la intoxicación por metilmercurio ocurrida en la bahía de Minamata y la intoxicación de Itai-Itai, producida por la presencia de cadmio en los alimentos de la zona afectada.
