“…This implies potential effects on the food web of the surrounding area as already reported by several authors studying marine systems (Riisgard and Hansen, 1990;Futter, 1994;Jarman et al, 1996;Atwell et al, 1998). This hypothesis is supported by the high mean HgT concentrations measured in pelagic species caught outside the bay, which are similar to those reported for other sites affected by Hg pollution: the Adriatic Sea (Wolfgang, 1983;Storelli and Marcotrigiano, 2001;Storelli et al, 2002Storelli et al, , 2004Storelli et al, , 2007Storelli et al, , 2010Gibičar et al, 2009), Turkish areas (Tuzen, 2009), Spanish coastal areas (Pastor et al, 1994) and Israel area (Hornung et al, 1980) (Table 2). …”

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.

Abstract. The pollution of the marine ecosystem is a world-wide problem. Heavy metals and organochlorine compounds are among the most harmful elemental pollutants and are of particular concern because of their toxicity to humans. Anchovy (Engraulis encrasicolus, Linnaeus 1758), small pelagic fish with a key ecological role in the marine food web, is an important link connecting the lower and upper trophic levels, being also a valuable species for human consumption. Thus, anchovy samples were collected from different stations along the Romanian Black Sea coast and the analyzed contaminants were organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and heavy metals (Cd, Pb, Ni, Cu and Cr) in muscle tissue. Cd and Pb are the heavy metals that exceeded the allowed levels under the EU legislation (0.3 μg/g), Cd recorded values within the range 0.29-0.51 μg/g (average 0.36 ± 0.09 μg/g) and Pb recorded values within the interval 0.29-1.62 μg/g (average 0.75 ± 0.57 μg/g). Regarding organochlorine pesticides, the highest level was recorded by p,p′-DDE (6.76±1.21 ng/g/dry weight), followed by p,p′-DDD (3.88±0.97 ng/g/dry weight). Among PCB's, the highest level was recorded by PCB 28 (5.19±1.29 ng/g/dry weight). The results of this study revealed that heavy metals, pesticides and polychlorinated biphenyls values identified in anchovy tissue, species of commercial interest from the Black Sea, are not threatening to human consumers.

“…Due to the fast development of industry and agriculture, As was released to estuarine and coastal environments with an average amount of more than 5000 tons/year from 2007 to 2010 in China from a variety of ways (e.g. the discharge of waste waters from mining and smelting, fertilizing and pesticides) (Mandal and Suzuki, 2002;Bissen and Frimmel, 2003;Tuzen, 2009;Wu et al, 2013;Gao et al, 2014).…”

“…Arsenic (As) is involved in many chemicals and exists in a number of inorganic and organic forms in marine environment (Hughes et al, 2011;Mandal and Suzuki, 2002;Tuzen, 2009). As an environmental pollutant, arsenic is toxic to marine organisms (Neff, 1997).…”

h i g h l i g h t s g r a p h i c a l a b s t r a c tAs (III) and As (V) induced differential proteomic responses in mussels. As (III) and As (V) induced osmotic and immune stresses in mussels. As (V) disturbed energy metabolism at metabolite level in mussels.a r t i c l e i n f o a b s t r a c tInorganic arsenic (As) is a known pollutant including two chemical forms (arsenite (As III) and arsenate (As V)), in marine and coastal environment. Marine mussel Mytilus galloprovincialis is an important environmental monitoring species around the world. In this study, we focused on valence-specific responses of As in juvenile mussel M. galloprovincialis using a combined proteomic and metabolomic approach. Metabolic responses indicated that As (III) mainly caused disturbance in osmotic regulation in juvenile mussels. As (V) caused disturbances in both osmotic regulation and energy metabolism marked by different metabolic responses, including betaine, taurine, glucose and glycogen. Proteomic responses exhibited that As (III) had a significant negative effect on cytoskeleton and cell structure (actin and collagen alpha-6(VI) chain). As (V) affected some key enzymes involved in energy metabolism (cytosolic malate dehydrogenase, cMDH) and cell development (ornithine aminotransferase and astacin). Overall, all these results confirmed the valence-specific responses in juvenile mussels to As exposures. These findings demonstrate that a combined metabolomic and proteomic approach could provide an important insight into the toxicological effects of environmental pollutants in organisms.
