“…25 Concentrations of Cd and Zn over the local legislative limits were found. 20 Liang et al 26 found that Cu and Zn contents of Crassostrea talienwhanen were 27.3 and 135 µg g −1 , respectively. Abbe et al 19 reported that mean monthly Cu concentrations of Crassostrea virginica ranged from 70 to 200 µg g −1 , and Cd concentrations ranged between 6 and 15 µg g −1 .…”

Pearl oysters (Pinctada radiata) were investigated for proximate and elemental composition throughout the year. Oysters were collected bimonthly by hand during scuba diving from the Gulf of Antalya. Ranges of dry matter, protein, fat and ash contents were 144.7-209.8, 65.9-160.4, 4.3-10.9 and 4.6-27.0 g kg −1 , respectively. While the highest protein and fat values were found in the summer months, the highest dry matter and ash contents were found in the winter months. The highest element contents were found in the spring and autumn months. Cadmium and zinc were found to be over the legislative limits, while copper was below, throughout year. The highest concentration among the elements was obtained for zinc.

“…Other studies focused on M. galloprovincialis and R. venosa showed that these species can be used as ecological indicators [35,36]. Due to its capacity for bioaccumulation of Cd and Ni in high concentration, R. venosa is used as biomonitor to control the aquatic contaminations with heavy metals [37].…”

The aim of this research was to study the accumulation of heavy metals (cadmium - Cd, lead - Pb, chromium - Cr, nickel - Ni, and copper - Cu) from water and sediments into living tissues of relevant marine species from different trophic levels of a food web, representative for shallow waters of the Romanian Black Sea Coast where the main anthropogenic impacts exist. The heavy metals concentrations were analysed by using an Atomic Absorption Spectrometer with graphite furnace, the results being further used to calculate the bioconcentration factors for a few key taxa like green and red algae, molluscs and fishes. Seven sampling sites influenced by anthropogenic pollution sources (municipal wastewater treatment plants and diffuse sources) were considered and a total of 300 samples were analysed for the period 2011-2012, this being the first unitary study for the Romanian Black Sea marine ecosystem. In 2011 and 2012 there were no significant differences between the sampling areas considering the heavy metals concentrations in water. For the sediments significant differences were observed between sampling sites for some heavy metals, namely Pb in 2011 and Pb, Cu and Cd in 2012, the highest concentrations being registered in the southern sector of the Romanian Black Sea shore, where the anthropogenic pollution sources are represented by the harbour and wastewater treatment plants. The values of the bioaccumulation factors (BCFsed) shows that algae are good accumulators for Cu>Pb>Ni>Cr>Cd, in comparison with BCFwater where the order of heavy metal accumulation was different: Cr>Ni>Pb>Cd>Cu. Molluscs have higher bioconcentration factors for Cu and Cd for sediments and for Cu and Ni for water. Rapana venosa accumulated more Cd and Cu. For fishes, Pb, Cu and Ni had the highest values in the tissues of benthonic species Mullus barbatus. In bivalve molluscs and fishes, in the majority of cases, there were not recorded exceeding mean concentrations as compared to the maximum allowed concentrations for Cd and Pb.

“…The R. venosa collected by divers in the Black Sea is consumed in Turkey and exported to Japan (Bat et al, 2000). This species has been used as a contamination indicator in various studies (Öztürk and Öztürk, 1994;Bat et al, 2000;Altug and Güler, 2002;Liang et al, 2004;Çulha Türk, 2007;Das et al, 2009;Moncheva et al, 2011;Ros ßioru et al, 2013).…”
