We assessed the relationship between V, Cr, Mn, Hg, As, Cd, Sn, Sb and Pb concentrations in Mytilus galloprovincialis samples from the coasts of Sicily and the expression of metallothioneins.

Abstract

We assessed the relationship between V, Cr, Mn, Hg, As, Cd, Sn, Sb and Pb concentrations in Mytilus galloprovincialis samples from the coasts of Sicily and the expression of metallothioneins. Toxic mineral elements assessment was carried out by A.A. Spectrometry and ICP-MS. The metallothioneins expression was performed by q-PCR method. Low metals' levels were found in the mussel samples examined, in comparison with what was reported in literature. The highest mean values of toxic mineral elements were found in Gela (Cr 0.178 +/- 0.03 mg/Kg, Mn 4.325 +/- 0.012 mg/Kg, As 3.706 +/- 0.009 mg/Kg, Sn 0.148 +/- 0.014 mg/Kg, Sb 0.009 +/- 0.004 mg/Kg e Pb 0.364 +/- 0.01 mg/Kg). Significant levels of Hg were found in samples from Catania (0.014 +/- 0.005 mg/Kg). Only vanadium and lead concentrations showed significant differences between sampling areas (p < 0.05). Molecular analysis verified a basal expression of Mt1 and the absence of over-expression of Mt2, confirming the low mineral's concentrations found in the samples examined.
