“…This difference is thought to be since the individuals used in both studies are not the same species and also the different pollution loads and amounts in their regions. Corrias et al (2020) conducted a study to determine the metal averages of Al, Cd, Cr, Cu, and Fe, which show accumulation in sea anemone Anemonia sulcata in 6 different stations of the Mediterranean region of Sardina. They calculated that the highest accumulation was Fe (80.828±24.108 mg/kg) and the lowest accumulation was Cd (0.002±0.003 mg/kg).…”

The purpose of this study was to determine the accumulation levels of ten metals (Fe, Zn, Cd, Cu, Co, Ni, Al, Mn, Pb, and Cr) in the muscle tissues of Actina equina indvduals. A total of 120 individuals of A. equina were collected at six different stations in İskenderun Bay in spring 2013. The accumulation levels of heavy metals in the tissues were found to vary significantly among stations. The mean concentrations of Fe were the highest at Samandağ station (105.11 ± 74.28 mg/kg) whereas the lowest average value of Co (0.84 ± 0.10 mg/kg) was obtained at Dörtyol station. Heavy metal concentratıons in muscle tissue of A. equina were ordered as Fe>Zn>Mn>Al>Cr>Cu>Pb>Ni>Cd>Co, respectively. This study is the first detailed bioaccumulation study conducted with A. equina in İskenderun Bay.

“…Also, a transfer of contaminants to humans through the food chain may occur. Biomonitoring studies represent a necessary tool to evaluate the environmental behaviour of elements potentially harmful for both humans and other living organisms (Corrias et al, 2020b). Anthropogenic activities are considered the primary source of metal pollution in aquatic ecosystems.…”

“…Hg and As sample preparations were carried out using an Agilent VGA-77 instrument (Agilent, Milan, Italy) according to the manufacturer instructions (Beach, 2010;Evans et al, 2010). Analysis was carried out using a Varian 710ES ICP optical emission spectrometer (Agilent, Milan, Italy), according to Corrias et al (2020b). Each measurement was conducted in triplicate.…”

This paper reports heavy metal and metalloid accumulation in wild brown trout (Salmo trutta L., 1758 complex) raised in freshwater and uncontaminated Sardinia system (Italy). Metals are widespread pollutants of aquatic systems, and their contamination can originate from anthropogenic activities such as industrial waste, agricultural and domestic environments, and geochemical release. Fish has a relevant position within the human diet; moreover, fishes can accumulate metals, making them a valuable tool as biomarkers for risk assessment studies. The concentration of 22 metals and metalloids after chemical digestion was assessed by inductively coupled plasma-optic emission spectroscopy (ICP-OES) in both the guts and the edible part (EP, muscle + skin) of brown trout. The results, expressed as μg g−1, showed different levels of accumulation in the EP and guts, following the series Cu > Zn > Ba > Al > Sr > Fe > Pb and Fe > Al > Hg > As > Mn > Cu > Ba > B > Zn > Pb, respectively. PCA analysis showed a fairly good correlation between the total lipid and SAFA content and Cd, Hg, and Pb accumulation in the gut. Non-carcinogenic risk assessment, expressed as THQ (target hazard quotient), showed values far below 1 for all metals in muscles, while high As and Hg contamination of the gut draws attention to possible health risks which should be discarded from the fish before consumption. TR (target cancer risk) values showed alarmingly high values for As and Cd when the fish were consumed entirely (gut + EP), while Pb levels were far below the safety levels.

Bottarga is a high-priced delicacy with high nutritional value, and, in Italy, bottarga from mullets has been recognized to be a traditional food product. The flathead grey mullet Mugil cephalus and the thinlip grey mullet Liza ramada are the main cultured grey mullets in the Mediterranean Sea. In this study, fresh roe and bottarga from these two species were investigated to evaluate the influence of the technological process and the species on their biochemical composition and health advantages. The 1 h/200 g salting-out step did not increase the levels of NaCl in the bottarga, although it highly decreased the levels of some heavy metals like Cu and Al. Processing of fresh roe in bottarga led to an essential modification of the lipid fraction, following a general series of monousatturated fatty acid (MUFA)> poliunsutturated fatti acid (PUFA) > saturated fatty acid (SAFA) and an increase in both ω3 and ω6 in Liza ramada. Moreover, bottarga showed higher levels of squalene and cholesterol and an increased Essential Amino Acid/Total Amino Acid ratio (EAA/TAA) in both species. In addition to the nutritional benefits for the consumer, the process proposed in this study may represent a reliable tool for local producers to obtain a final bottarga with both a reproducible biochemical composition and organoleptic characteristics.
