Monthly variation of micro- and macro-element composition in smooth scallop, Flexopecten glaber (Linnaeus, 1758), from the Çardak Lagoon (Çanakkale Strait, Turkey)

Abstract

The present study investigated the total elemental composition (Fe, Cu, Mn, Zn, Al, S, B, Na, Mg, K, Ca, P, S) in smooth scallop (Flexopecten glaber) meat collected monthly in the Çardak Lagoon (Turkey) in 2017- 2018. Considering the distribution of elements in terms of quantity during the year, the elements were sorted as S> Na> K> P> Mg> Ca> Fe> Zn> Mn> Al> B> Cu> Se and the heavy metals were below the detection limit. Although the elements were at their highest values during autumn and summer, they were at their lowest values during spring and winter. The differences between the months in terms of Fe, Mn, Mg, and Ca elements were found to be statistically significant (p <0.05). It was determined that the element composition of smooth scallop meat was suitable for consumption in terms of the area where it is collected and is beneficial for health when consumed in the amounts recommended by FAO/WHO, and CODEX. The Hazard Quotient (THQ) and the Hazard Index (HI), which was conducted to evaluate the health risks of consuming smooth

Amino Acid Composition in Different Tissues of Iceland Scallop from the Barents Sea

“…In the three tissues analyzed, glycine and arginine were identified as the dominant amino acids. Similar predominance of these amino acids, particularly glycine, has been documented in the adductor muscle of several scallop species including the Pacific lions-paw scallop (Nodipecten subnodosus) at Laguna Manuela, Mexico [29], the king scallop (Pecten maximus) from France and Norway, the Atlantic sea scallop (Placopecten magellanicus) from the Northwest Atlantic Ocean [30], the smooth scallop (Flexopecten glaber) from the Çardak Lagoon, Türkiye [31], the bay scallop (Argopecten irradians) in the North China Sea [32], and the Yesso scallop (Mizuhopecten yessoensis) in the Yellow Sea, China [33]. Substantial glycine concentration has also been detected in the muscle of the Mediterranean scallop (Pecten jacobaeus) from the Gulf of Antalya, Türkiye [34], as well as in the Zhikong scallop (Chlamys farreri) from the Yellow and Bohai Seas, China [35].…”

Monthly variation of fatty acids, lipid quality index and metal content of Pontastacus leptodactylus (Eschscholtz, 1823) in Atikhisar Dam Lake (Çanakkale, Türkiye)

“…Al, the third most abundant element in the Earth's crust, is extensively used in developing industries (Bohrer et al 2008). High levels of Al accumulation can lead to chronic kidney diseases and neurological disorders in humans (Bondy 2016;Vural and Acarlı 2021). Al concentrations in both female and male individuals were lowest in August (5.66 ± 0.109 and 2.51 ± 0.042 mg kg −1 ww, respectively) and highest in male individuals in September (55.00 ± 2.901 mg kg −1 ww) and in female individuals in October (33.70 ± 0.756 mg kg −1 ww).…”

Exotic Polychaetes of a Sewage Pollution Influenced Lagoon (Çardak Lagoon, Turkish Straits)

“…It is a leaky type lagoon with a coastline of 4.3 km, a surface area of 1.2 km 2 , and an average depth of 1.3 m, having a rich natural habitat. The commercial marine bivalves harvested in Çardak Lagoon are the venerid clam Chamelea gallina (Linnaeus, 1758), scallop Flexopecten glaber (Linnaeus, 1758), Mediterranean mussel Mytilus galloprovincialis (Lamarck, 1819), carpet shell clam Ruditapes decussatus (Linnaeus, 1758), Manila clam Ruditapes philippinarum (Adams, 1850), and oyster, Ostrea edulis (Linnaeus 1758) [15]. Çardak Lagoon was declared a first-degree natural site by the Council for the Protection of Cultural and Natural Assets in Türkiye (Decree No.…”
