“…The lowest temperature was observed in January at S-5 (7°C), located toward the center of the lagoon, and the highest temperature at S-1 in September (33.8°C), located near the west coast of the lagoon. Lagoon temperature is recognized as a significant factor impacting freshwater, in association with low TDS m i x i n g i n t o h y p e r -s a l i n e l a g o o n w a t e r (Diamantopoulou et al 2008).…”

The water quality of the Akyatan Lagoon was characterized using hydrochemical methodology. The lagoon is located on the Mediterranean coast and is the largest wetland ecosystem in Turkey. In addition, the lagoon is classified as a hyper-salinity wetland. Water samples were collected monthly between December 2007 and November 2008. Eleven stations within the lagoon were determined, and triplicate grab samples were obtained from each station to characterize water quality as follows: T °C, pH, total alkalinity (TAlk), dissolved oxygen (DO), total dissolved solids (TDS), salinity, electrical conductivity (EC), and main anions, including chloride (Cl(-)), nitrates (NO3 (-)), and sulfate (SO4 (2-)). Results from selected stations indicated varying TDS, EC, salinity, and Cl(-) concentrations, from 20,892 to 175,824 mg/L, from 35.7 to 99.6 mS/cm, from 22.3 to 71.0 ppt, and from 14,819 to 44,198 mg Cl(-)/L, respectively. Data indicated that the spatial distribution of water quality parameters was significantly affected by freshwater input via the constructed drainage channels which collect water from a catchment area and discharge water into the lagoon as a point source, thus preventing drainage water to reach the lagoon as a nonpoint source.

“…Hydro-Bios polypropylene bottles were used for water sampling. Water samples were filtered sequentially through 8 mm and 0.45 mm Millipore nitrocellulose filters and stored in a refrigerator at 4 C. All samples were handled in a laminar flow bench in order to avoid any contamination [8]. Filtered samples were pre-concentrated by passing through Chelex 100 resin columns.…”

“…The sampling stations were selected in such a way to cover all parts of the lagoon: the north (stations 6,8,9), the central (stations 1, 3, 7) and the south (stations 2, 4, 5). Station 10 was located outside the lagoon, in the Mediterranean Sea, in order to be used as a reference station.…”

A B S T R A C TMar Menor lagoon is one of the largest hypersaline coastal lagoons in the Mediterranean Sea. The lagoon is threatened by environmental degradation due to the urban growth around it, the intensive agriculture in its watershed and the remains of mining activities in the nearby Cartagena-La Unió n area. The present study aims at estimating the levels of zinc and lead in the water column, sediments and marine flora and fauna of Mar Menor lagoon. The ranges of the total concentrations in the water column were 9.36-28.7 mg/L for Zn, 1.61-12.6 mg/L for Pb and 3.01-29.70 mg/L for Mn. Zinc was mostly found in the dissolved phase (70%) whereas lead and manganese in the suspended phase (63-76%). Highest values were measured at stations closer to streams flowing trough drainage basins including agricultural zone and the mining remains. Concerning sediments, the values were very high especially at the southern part, indicating transport of suspended matter from currents. The metal content in the sediments is higher than the content in particulate matter and there is an increased bioavailability of Zn and Pb. Zinc and lead were measured in the thallus of four marine flora species. Maximum zinc concentration was measured in Cymodosea nodosa (132 mg/g) and maximum lead in Acetabularia acetabulum (93.5 mg/g) in samples from the southern lagoon. From the two benthic fauna species studied, it was observed that heavy metals accumulate mostly in the animal flesh. The highest concentration of Zn and Pd was measured in the flesh of the mollusk Ostrea edullis with values of 1,856 and 51.0 mg/g respectively. These values reveal the effect of heavy metal pollution in the lagoon ecosystem.

“…Lagoonal waters may receive significant quantities of nutrients, heavy metals and pollutants (Sfriso et al 1992, Cobelo-García et al 2012, Prado et al 2014). Their shallowness along with the synergistic effect of the wind are responsible for the resuspension of the nutrients from the sediments and their further distribution to the water column through mixing (Diamantopoulou et al 2008, Pérez-Ruzafa et al 2011). …”

BackgroundCoastal lagoons are ecosystems of major importance as they host a number of species tolerant to disturbances and they are highly productive. Therefore, these ecosystems should be protected to ensure stability and resilience. The lagoons of Amvrakikos Gulf form one of the most important lagoonal complexes in Greece. The optimal ecological status of these lagoons is crucial for the well-being of the biodiversity and the economic prosperity of the local communities. Thus, monitoring of the area is necessary to detect possible sources of disturbance and restore stability.New informationThe environmental variables and heavy metals concentrations, from five lagoons of Amvrakikos Gulf were measured from seasonal samplings and compared to the findings of previous studies in the area, in order to check for possible sources of disturbance. The analysis, showed that i) the values of the abiotic parameters vary with time (season), space (lagoon) and with space over time; ii) the variability of the environmental factors and enrichment in certain elements is naturally induced and no source of contamination is detected in the lagoons.
