[Influence of the accumulation of Cr, Cd and Pb on the pool of free tissue amino acids in Mytilus galloprovincialis in various zones of the bay of Naples].

The Authors investigated on the relations between the amount of Heavy Metals (Me) and free aminoacids (FAA) from tissues of Mytilus galloprovincialis. Similar mussels were collected from three sampling zones of bay of Naples. The analyzed Me were Cr+3, Cd+2, Pb+2. The obtained results show that behaviour of Me and FAA is similar. These data suggested to the Authors that FAA changes have to be related to an attempt to recover their's equilibrium more than a direct influence of Me on mussel's FAA metabolism.
