Toxic mineral elements in Mytilus galloprovincialis from Sicilian coasts (Southern Italy)

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.

Trace Elements and Omega-3 Fatty Acids of Wild and Farmed Mussels (Mytilus galloprovincialis) Consumed in Bulgaria: Human Health Risks

“…Cd concentration in the literature ranged between 0.292 ± 0.008 mg/kg ww and 0.970 ± 0.043 mg/kg ww in M. galloprovincialis from the Marmara Sea, Turkey [ 41 ], up to 0.201 ± 0.025 mg/kg ww for the same bivalve species from the Sicilian coast, Italy [ 53 ], and between 0.09 ± 0.005 and 0.91 ± 0.02 mg/kg in D. trunculus , C. gallina and M. galloprovincialis in our previous study of the Black Sea, Bulgaria [ 11 ]. The current values do not exceed the limit of 1.0 mg/kg set by the European Commission [ 35 ].…”

Salmo salar fish waste oil: Fatty acids composition and antibacterial activity

“…Aquaculture fish management practices can represent an important stressing factor for fishes, in particular for salmon, and could result in high mortalities leading to significant economic loss for producers (Wilson et al, 2009;Sudheesh et al, 2012;Overton et al, 2019). In fact, stressors like handling, stripping of brood stock, antimicrobial treatments, vaccination, temperature, crowding, starvation and transport can result in an increase of a number of diseases evaluable through the measure of the levels of cytokines, heat shock proteins (HSP), corticosteroid hormones, immunoglobulin and immune cells levels, haematological parameters (Gabriel & Akinrotimi, 2011;Cordero et al, 2016;Rehman et al, 2017;Parisi et al, 2017;Chiaramonte et al, 2019;Cammilleri et al, 2019a;Inguglia et al, 2020;Vazzana et al, 2020). Moreover, salmon, which are usually farmed in crowded conditions, are easily targeted by infective pathologies (Poppe, Barnes & Midtlyng, 2002;Håstein, 2004;Bang-Jensen, Gu & Sindre, 2019).…”

Essential and non-essential elements in white lupin ( Lupinus albus L.) cultivated in Southern Italy

“…The repeatability limit was calculated by adding to 15 digested samples spiked 1.00 -2.00 to 5.00 µg / L of all analytes. repeatability and reproducibility within-laboratory was calculated according to Cammilleri et al (2019); all the two values must be smaller than 2.…”
