Manganese and “pinnaglobin” in Pinna nobilis

High metal contents in the fan mussel <em>Pinna nobilis</em> in the Balearic Archipelago (western Mediterranean Sea) and a review of concentrations in marine bivalves (Pinnidae)

“…A second study by Catsiki et al (1994) with specimens collected in the Geras Gulf and the Kalloni Gulf (Greece) found the same pattern regarding tissue accumulation, although it determined lower metal concentrations in the specimens from the Kalloni Gulf and a higher Cr impact in the Geras Gulf due to additional inputs by tannery effluents. Mathew et al (1996) determined nine metals in the extrapallial fluid of two individuals (data in wet weight, Table 2), showing that both hemolymph and extrapallial fluid plasma contained Mn(II) at concentrations over five orders of magnitude higher than those normally found in seawater. More recently, Rabaoui et al (2014) studied four metals (Cd, Hg, Pb and Cr) in different parts of P. nobilis among several localities of the Gulf of Gabes (Tunisia).…”

“…So far, five studies have reported the accumulation of metals in P. nobilis in the Mediterranean: two were carried out in Greece Katsilieri 1992, Catsiki et al 1994), one in France (Mathew et al 1996), and two recently in Tunis (Rabaoui et al 2014, Jebali et al 2014. These studies determined various metals in different parts of the specimens within a variety of field experiment approaches.…”
