“…The estimated values of present-day seawater lead contents(Table 5supplementary materials)are in good agreement with data from the central Adriatic Sea in 2004 of 130 pmol/L(Annibaldi et al, 2009) and data from the outer Saronikos Gulf, Greece, of 128 pmol/L (median value between 2000 and 2010)(Paraskevopoulou et al, 2014). Nevertheless, some specific areas in the Mediterranean Sea still have high Pb concentrations, such as the Ancona coast of the Central Adriatic Sea [560 pmol/L,(Annibaldi et al, 2011)], or the inner Saronikos Gulf [2600 pmol/L,(Paraskevopoulou et al, 2014)].…”

Lead (Pb) profiles in red coral skeletons as high resolution records of pollution in the Mediterranean Sea

Lead concentrations in long-lived Corallium species of known age, from the Mediterranean Sea, Atlantic and Pacific Oceans, were determined by laser ablation, inductively coupled plasma mass spectrometer (LA-ICPMS). Lead concentrations in a 2000-year-old sub-fossil Mediterranean C. rubrum are ca 0.09 ± 0.03 µg/g. For the period 1894-1955, lead concentrations in C. rubrum skeletons from the Mediterranean are stable within the range 0.2-0.4 µg/g; concentrations increase to about 1-1.2 µg/g during the period 1960-1978, then decrease progressively to stabilize and reach values in the range 0.2-0.4 µg/g in present-day corals. These variations can be related to the lead gasoline pollution event that (1) started in the early 1950s with the increase of the numbers of cars in the world, and (2) was mitigated by the implementation of new regulations starting in 1975, leading to a return to pre-1950 levels in 2000. In the Pacific, lead concentrations in C. japonicum and C. konojoi are lower than in the Mediterranean C. rubrum, with values close to 0.17 ± 0.03 µg/g. The lowest lead concentrations in present-day samples (0.11 µg/g) are found in C. johnsoni and C. niobe from the Azores islands in the Atlantic, and in a Mediterranean C. rubrum from Montecristo Island, one of the least accessible and most protected areas in the Mediterranean Sea. Using lead concentrations in C. rubrum and in the Mediterranean seawaters, a partition coefficient Kd = [Pb/Ca] calcite / [Pb/Ca] seawater of 13 +/-3 is estimated; it allows calculating past and present lead contents in seawater in which corals grew. Application to Corallium species indicates that values endangering human health or threatening the preservation of aquatic ecosystem on long terms were nearly reached or exceeded in Mediterranean seawaters at the maximum of the lead gasoline pollution event in the 1980s. Measurements in C. rubrum from different places in the Mediterranean indicate that present-day seawater concentrations vary between 2 40 and 200 pmol/kg. As expected, the lowest concentrations come from protected areas insulated from human activities, while the highest come from places close to lead mining or processing sites.

“…Reliable and accurate measurements of elements at trace and ultra-trace concentrations (Table 11) are needed in a variety of research activities. LEC-NKUA utilizes conventional atomic absorption spectrometers and inductively coupled plasma-mass spectrometry (ICP-MS) for the determination of multiple elements in various contaminant monitoring and bioaccumulation studies [42][43][44][45][46]. Inductively coupled plasma-mass spectrometry (ICP-MS) (Figure 18) is a powerful technique to measure the level of trace metal contamination and assess environmental status, and is advantageous in that ionization is more complete as it occurs in a chemically inert environment, preventing oxide formation.…”

Research infrastructures have been established throughout Europe in order to create robust organizations that will facilitate and enhance research and innovation processes and will advance society with innovative products and services. The Hellenic Integrated Marine Observing, Forecasting and Technology System (component of HIMIOFoTS RI) has been implemented in the framework of the National Roadmap for Research Infrastructures to form a large-scale infrastructure for the marine environment in Greece. It links together ocean observing and forecasting systems, coastal zone monitoring and management practices, as well as ocean engineering testing facilities. The overarching framework of the system supports the coordination of five organizations with expertise in the field of marine science and technology, the central management of research activities, and the common development of services and products. It comprises facilities and resources while it provides open access to research communities (academia, industry) to support the scientific advancements and innovation in their fields. The Hellenic Marine Observing, Forecasting and Technology System was further enhanced during its implementation through significant upgrades and developments in order to extend its observing capacity and the forecasting and technological abilities, while advancing the provided services and products.

“…The daily discharge of pollutants from human activities such as industry, agriculture, shipping, ports, domestic waste and anthropogenic pressure is a serious problem that has harmful effects on aquatic organisms (Paraskevopoulou et al 2014). Many animals and plants living in polluted environments are often exposed to complex mixtures of chemical contaminants (Sureda et al 2011), and these species have been proposed as a biomonitor of pollutants in coastal areas (Bodin et al 2011).…”

Our study aimed to evaluate the effect of trace element pollution in the polychaete Perinereis cultrifera (Grube, 1840) from two Tunisian coasts (the port of Rades, S1; and the Punic port of Carthage, S2). To this end, we used an approach based on proximate composition, biomarker responses and trace element bioaccumulation. Our results showed a decreasing order of metals concentrations (Zn>Cu>Cd>Pb) in P. cultrifera from S1 and S2. The accumulation of Cd, Cu and Zn was significantly higher in S1 than in S2, especially in summer. Lipid, protein and glycogen content also changed significantly between S1 and S2 in relation to trace metal accumulation and environmental conditions. The results revealed a higher level of thiobarbituric acid in P. cultrifera from S1 than from S2. In addition, the enzymatic and non-enzymatic antioxidant defence system (catalase, glutathione-S-transferase, superoxide dismutase, glutathione and metallothionein) was enhanced and acetylcholinesterase activities decreased in P. cultrifera in S1 in comparison with S2. A principal component analysis showed that P. cultrifera from S1 exhibited a clear disruption of oxidative stress responses and trace element bioaccumulation among seasons. Overall, these findings revealed the sensitivity of those organisms to environmental conditions.
