“…High Zn concentrations were also found by Strogyloudi et al (2014) in the sea urchin Paracentrotus lividus used as a bioindicator species in Amvrakikos Gulf. Karageorgis (2007) and Vasileiadou et al (2016) highlighted that the metal enrichment in the gulf results from natural processes rather than anthropogenic stressors, which seems consistent with the results of the present study.…”

“…Characterized by a complex system of lagoons, extensive delta formations, salt meadows, marshlands, and swamps, it is a shallow semi-enclosed gulf connected with the Ionian Sea through a narrow channel. It is protected by the Ramsar, Barcelona, Berne, and Bonne Conventions and has been declared a national park (2008) (Tsangaris et al, 2010;Vasileiadou et al, 2016). The rivers Vovos, Krikeliotis, Arachthos, and Louros drain into the gulf, with the two latter discharging contaminants carried from agricultural land (Tsangaris et al, 2010;Karaouzas et al, 2021;Tzempelikou et al, 2021).…”

Sardine and anchovy as bioindicators of metal content in Greek coastal waters

Metal and element concentrations (Li, Na, Mg, P, Ca, V, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Mo, Pd, Cd, Cs, Ba, Hg, Tl, Pb, U) were monitored in the tissues of sardine (Sardina pilchardus) and anchovy (Engraulis encrasicolus) from six Greek coastal areas subjected to different natural and anthropogenic forcings in order to be assessed as bioindicator species of marine metal pollution. Sardine and anchovy provided a thorough view of the metal pollution load of each site in accordance with local pollution sources. The wide range of pressures applied in Elefsina Gulf and Thermaikos Gulf are depicted in the large number and the kind of elements reaching maximum concentrations among the sites (e.g. Pb, Cu, Hg, As in Elefsina Gulf, and Cd, Ni, P in Thermaikos Gulf) while in the rest of the sites (Amvrakikos Gulf, Strymonian Sea, Thracian Sea, Artemisium Straits), few elements were found at maximum levels. Statistically significant site-specific differences in metal content were detected. The differentiation in metal content of the fish tissues among the sites could be attributed to anthropogenic pressures, different background levels and environmental conditions. Sardine and anchovy can be evaluated as appropriate, reliable and useful bioindicator species of marine metal pollution.

Incessant monitoring of water is essential in terms of heavy metals and toxic substances as it provides detailed information on aquatic resources. Majority of lagoons receive freshwater from their catchment areas containing industrial and domestic waste. The paper analysed seasonal variations in the distribution and concentrations of Lead (Pb), Copper (Cu), Cadmium (Cd), and Manganese (Mn) in the Fosu lagoon in Ghana to ascertain the quality of the lagoon. Water was sampled from eighteen (18) different points on the lagoon and was analysed at the Water Research Institute (WRI) of the Center for Scientific and Industrial Research (CSIR) using Atomic Absorption Spectrometry (AAS) and the results were interpolated using kriging. The results obtained were compared with the World Health Organisation water quality index. Statistical analysis of heavy metal concentrations using Pearson’s two-tailed significance correlation showed positive correlations for both seasons; between Pb and Cu (0.297; sig. = 0.232, and 0.196; sig. = 0.436), and Cd and Mn (0.119; sig. = 0.643 and 0.191; sig. = 0.447) for the wet and dry seasons respectively. A paired sample t-test on concentrations also showed statistical differences between wet and dry seasons’ concentrations for Pb (t = 1.324; sig. = 0.203), Cu (t = 2.759; sig. = 0.013), and Cd (t = 3.056; sig. = 0.007), and Mn (t = -4.014; sig. = 0.001). Pb and Cd showed higher concentrations above the World Health Organisation's permissible limits. Heavy metal concentrations of water samples analysed varied widely in terms of seasons and sampling points.

“…As for their characteristics, the coastal lagoons are mostly shallow, with maximum depths of up to ten meters, except those where the connection with the sea is open and are used for navigation, so they have up to 58 m as the deepest value [26] in the case of the Gulf of Amvrakikos (number 27). The maximum extension is presented in the Razim-Sinoie lagoon (number 25), located in the Danube delta [16], with an area of 1292 km 2 .…”

Mediterranean Coastal Lagoons Review: Sites to Visit before Disappearance

Coastal lagoons are an established priority habitat in the European environment because of the biological communities that inhabit them. Their origin is related to the transport of sediments from a nearby river or the movement of sands by the marine currents that produce the closure of a gulf. Therefore, they are recent geological formations, which also disappear quickly if environmental conditions change. The 37 coastal lagoons with a surface area greater than 10 km2 located in the Mediterranean basin have been identified. Fishing has been the traditional use of these lagoons, in addition to their use as a navigation harbor when they are open to the sea. Pollution, quality problems and their consequences are the most studied topics in recent publications. Sentinel-2 images taken in the summer of 2020 have been used to study water transparency, suspended matter and chlorophyll a concentration. The result was that only six of them are in good ecological condition, but most of them are eutrophic due to the impacts on their environment and the inflow of poor quality water. The cultural values of these lagoons must also be protected and preserved.
