“…However, detailed investigations on different groups of species and on a wide range of HgT concentrations are lacking and, when available, sometimes controversial (Stafford and Haines, 2001), especially for fishes with low mercury levels (average below 0.2 ppm) (Park and Curtis, 1997; Burger and Gochfeld, 2011). Strong correlations between size and Hg levels in fish are reported for Swordfish (Xiphias gladius) and Bluefin Tuna (Thunnus thynnus) from the Mediterranean Sea (Storelli and Marcotrigiano, 2001), for several pelagic fish species from the Adriatic Sea (Storelli, 2008) and for S. pilchardus specimens from Tunisia (Joiris et al, 1999). Furthermore, Burger et al (2007) found a positive correlation between size and Hg levels for 11 of 14 species of marine fishes collected in the western Aleutians (Bering Sea/North Pacific) and Luten et al (1987) found the same positive correlation in Atlantic Cod.…”

“…Accordingly, here we estimated health risk for Hg intake only on THQ and EWI parameters. These indexes are widely used to assess risk associated with fish consumption (Storelli et al, 2004(Storelli et al, , 2010Storelli, 2008;Martorell et al, 2011;Domingo et al, 2012). In particular, for no carcinogenic effects, an HQ exceeding 1.0 indicates a potential health risk (US EPA, 1989).…”

“…In the last decade, several studies have provided detailed information on the pollution levels and risks for human health of resident populations of Augusta Bay (ICRAM, 2005;Ausili et al, 2008;Di Leonardo et al, 2007, 2008ENVIRON International Team, 2008;Ficco et al, 2009;Sprovieri et al, 2011). Sprovieri et al (2011) reported high-resolution maps of HgT distribution from superficial sediments collected in 2005, highlighting extremely high concentrations (ranging between 0.1 and 527.3 mg kg À1 ) and speculating on the key role that Augusta Bay could play in exporting Hg to the Mediterranean Sea, as an effect of the outflow intercepted by the Levantine Intermediate Waters (LIWs).…”

a b s t r a c tOur study reports on the total mercury (HgT) concentrations measured in the muscles and livers of several benthic, demersal and pelagic fish species caught inside and outside of Augusta Bay (southern Italy), a semi-enclosed marine area, highly contaminated by the uncontrolled (since the 1950s to 1978s) discharge of the largest European petrochemical plant. Mercury levels in fish tissues are discussed with regard to specific habitat, size and/or age of the specimens and HgT distribution in the bottom sediments. Results suggest a still active Hg release mechanism from the polluted sediments to the marine environment. Also, the high HgT concentrations measured in fishes caught in the external area of the bay imply a potential role of Augusta Bay as a pollutant source for the Mediterranean ecosystem. Finally, values of hazard target quotient (THQ) and estimated weekly intake (EWI) demonstrate that consumption of fishes caught inside the bay represents a serious risk for human health. Also, data indicate that intake of fishes caught from the external area of the bay, especially for that concern demersal and benthic species, could be represent a significant component of risk for the local population.

Fish is an excellent, low-fat source of protein and provides many benefits, such as contributing to low blood cholesterol. Heavy metals are increasingly being released into natural waters from geological and anthropogenic sources. Due to the rapid development of agriculture and industry, and a historical lack of enforcement of regulations, the study areas have become contaminated by metals, especially cadmium (Cd) and lead (Pb) which has been emitted into the environment through atmospheric deposition, solid-waste emissions, sludge applications, and irrigations with wastewater.The health risks posed to the local inhabitants by exposure to Pb and Cd in two coastal regions of Iran through the consumption of contaminated fish were investigated, based on estimated target hazard quotients (THQs). The results showed that THQ values are less than 1 for both adults and children by either group consuming fish alone.The distribution of several heavy metals (Cd and Pb) was investigated in muscle and liver in six different fish species seasonally collected in the Persian Gulf (autumn 2008 -summer 2009). The concentrations of all metals were lower in flesh than those recorded in liver due to their physiological roles. The THQ index for fish was calculated. Estimation of target hazard quotients calculations for the contaminated fish consumption was calculated to evaluate the effect of pollution on human health. Total metal THQs values (Pb and Cd) for adults were 0.05 and 0.04 in Bushehr and Bandar-Genaveh, respectively, and for children was 0.08 and 0.05 in Bushehr and Bandar-Genaveh, respectively.The dietary intake of Pb estimated for the inhabitants in this area is far below the limit considered tolerable. The Cd intake through the consumption of fish is also less than the limit of daily dietary intake considered tolerable by FAO/WHO. RÉSUMÉ: L'évaluation des risques pour la santé des métaux lourds présents dans les produits alimentaires d'origine marine.Le poisson est un aliment excellent, une source de protéine maigre qui offre des nombreux bénéfices, tel que la contribution à la diminution du taux du cholestérol dans le sang. Les métaux lourds sont de plus en plus présents dans l'eau en provenance des sources géologiques et anthropiques. Dû au développement rapide de l'agriculture et de l'industrie ainsi qu'au manque historique d'application de la législation, la zone d'étude est devenue contaminée par des métaux lourds, plus particulièrement par le cadmium (Cd) et le plomb (Pb) qui se sont retrouvées dans le milieu en provenance des poussières atmosphériques, des déchets solides, des application des boues des usines de traitement des eaux usées ainsi que due à l'irrigation des cultures avec de l'eau usée. Les risques pour la santé représentées par l'exposition au Pb et au Cd des habitants de deux régions côtières d'Iran par la consommation des poissons contaminés ont été investigués en utilisant les quotients de danger cible estimés (les THQs). Les résultats ont montré que les valeurs THQ sont moins de 1 pour le...

“…However, overfishing has led to the development of aquaculture, which can be a viable solution to these problems. Mussels are an excellent aquaculture candidate, but they accumulate a wide range of metals in the meat (Romeo et Marine resources for human consumption have grown rapidly worldwide with the widespread use of seafood, which is recognized as important sources of protein, minerals and vitamins (Heu et al, 2003;Storelli, 2008;Hellberg et al, 2012). Shellfish has many nutritional advantages, but at the same time it poses health risks such as heavy metal contamination because they filter large quantities of water to extract their food and are good bioaccumulators (Guéguen et al, 2011;Grotto et al, 2012;Hellberg et al, 2012).…”

This study focuses on evaluation of the effects of 3 different thermal preparation methods (boiling, roasting, microwaving) on mineral concentrations of mussels from Bucharest market. The mineral content in raw and cooked mussel samples was evaluated by ICP-OES and relative humidity of raw and cooked mussels by thermogravimetry. Se level in microwaved samples was significantly decreased compared to raw and the other 2 cooked mussel samples. Zn concentration in raw samples was not significantly different compared to those in roasted samples. Fe level was insignificantly different between boiled and roasted samples and significantly lowers in microwaved samples. Ni, Pb, and Se levels were significantly higher in boiled samples, and Cd levels were insignificantly different reported to cooking method. The percentage of water loss during roasting was lower than the other 2 thermal preparation methods. Potassium concentrations in cooked mussels were higher compared to raw ones. Mineral concentrations were highest in roasted samples and heavy metal concentrations in boiled mussels.
