“…Unfortunately, there is little information about this problem. The present results showed that although the Mediterranean Sea is subjected to relative high inputs of pollutants (Kuetting, 1994, Turley, 1999, trace element concentrations in specimens from the Tyrrhenian Sea (South Western Mediterranean) are comparable or even lower than those determined in the same species from other areas (Table 4). For comparative purposes, data which were originally presented on a wet weight basis were converted to approximate dry weights using the mean water content of each tissue determined in this study (see Results section).…”

Trace element (Cd, Cu, Hg, Se, Zn) accumulation and tissue distribution in loggerhead turtles (Caretta caretta) from the Western Mediterranean Sea (southern Italy)

et al. 2005

Cadmium (Cd), copper (Cu), mercury (Hg), selenium (Se) and zinc (Zn) were determined in the liver, kidney and muscle of 29 loggerhead turtles, Caretta caretta, from the South Tyrrhenian Sea (Western Mediterranean). No significant differences (p>0.05) were detected between males and females. Trace element concentrations were not influenced by the size of the specimen except Se in the liver, which was negatively correlated with the curved carapace length (p<0.001). Muscles generally displayed the lowest trace element burdens, with the exception of Zn which contained concentrations as high as 176 microgg-1dwt. Kidneys displayed the highest Cd and Se mean concentrations (57.2+/-34.6 and 15.5+/-9.1 microgg-1dwt, respectively), while liver exhibited the highest Cu and Hg levels (37.3+/-8.7 and 1.1+/-1.7 microgg-1dwt, respectively). Whichever tissue is considered, the toxic elements had elevated coefficients of variation (i.e. from 60% to 177%) compared to those of the essential ones (i.e. from 14% to 65%), which is a consequence of homeostatic processes for Cu, Se and Zn. Globally, the concentrations of Hg remained low in all the considered tissues, possibly the result of low trophic level in sea turtles. In contrast, the diet of loggerhead turtles would result in a significant exposure to Cd. Highly significant correlations between Cd and Cu and Zn in the liver and kidney suggest that efficient detoxification processes involving MT occur which prevent Cd toxicity in loggerhead turtles.

“…Turkish fishermen catch albacore from the Eastern Mediterranean Sea, but publications on the concentrations of trace elements in T. alalunga from that region are very limited (Storelli et al, 2002;Storelli and Marcotrigiano, 2004). Due to its semi-closed nature, and since it is surrounded by large centers of human population, levels of marine contaminants are high in the Mediterranean Sea (Bacci, 1989;Borrell et al, 1997;Kuetting, 1994). It is known that the Antalya Coast of the Mediterranean Sea became polluted in recent years due to industrial and domestic waste (Ergin, 2005).…”

Albacore has been exported mainly to Europe from Turkey. To evaluate the possible health risks and provide information for surveillance programs, concentrations of cadmium, mercury, and lead were determined in albacore from the Eastern Mediterranean Sea. Of the 34 individuals, 25 contained mercury and 9 contained cadmium above the permissible limits set by the European Union (1 mg/kg and 0.1 mg/kg, respectively). None of the samples contained lead above the limit (0.3 mg/kg). It was concluded that concentrations of trace metals in albacore, especially mercury, must be controlled comprehensively and periodically with respect to consumer health.

“…This aspect is especially interesting for biota residing in contaminated marine areas. It has been often reported that the Mediterranean Sea is at high toxicological risk (Meadows 1992;Kuetting 1994), as a consequence of its particular hydrographical characteristics and high pressure of the human impact. The Adriatic Sea, in particular, is a shallow and semi-enclosed basin which receives some of the largest Italian rivers, such as Po, Adige, and Brenta.…”

Trace element concentrations (Hg, Cd, Pb, Cr, Ni, Cu, Zn) were determined in the muscle, gonads, skin, and brain of smooth hound Mustelus mustelus in order to define the metal distribution patterns. The data indicated that metal accumulation depended on the tissues probably as a consequence of metabolic needs, physiochemical properties, and detoxification processes specific for each element. Metal concentrations were higher in gonads (Hg 0.10-0.70 μg g(-1); Cd 0.02-0.10 μg g(-1); Pb 0.08-0.39 μg g(-1); Cr 0.06-0.36 μg g(-1); Ni 1.37-3.00 μg g(-1); Zn 9.15-16.30 μg g(-1); Cu 1.95-21.62 μg g(-1)) and skin (Hg 0.16-0.66 μg g(-1); Cd 0.01-0.04 μg g(-1); Pb 0.10-0.62 μg g(-1); Cr 0.15-0.68 μg g(-1); Ni 1.60-7.20 μg g(-1); Zn 9.00-16.00 μg g(-1); Cu 0.78-6.80 μg g(-1)) than brain (Hg 0.04-0.34 μg g(-1); Cd 0.01-0.05 μg g(-1); Pb 0.03-0.59 μg g(-1); Cr 0.08-0.48 μg g(-1); Ni 5.59-9.69 μg g(-1); Zn 5.90-7.35 μg g(-1); Cu 0.90-4.02 μg g(-1)), while muscle always exhibited the lowest levels (Hg 1.03-2.58 μg g(-1); Cd 0.01-0.06 μg g(-1); Pb 0.02-0.16 μg g(-1); Cr 0.05-0.28 μg g(-1); Ni 1.13-2.48 μg g(-1); Zn 2.64-5.06 μg g(-1); Cu 0.33-2.23 μg g(-1)). Ni and Hg took exception having the highest concentrations in brain and muscle, respectively. An assessment of the risk for human due to the consumption of these marine organisms was also undertaken. Regarding Cd and Pb intakes, consumption did not guide to any concerns, while it should be extremely moderate when considering Hg intake. The comparative analyses revealed that Mediterranean sharks were exposed to higher Hg levels than biota inhabiting open ocean.
