Changes in the tissue concentrations of trace elements during the reproductive cycle of Noah's Ark shells (Arca noae Linnaeus, 1758)

Abstract

Concentrations of 23 trace elements (TEs; essential: Co, Cu, Fe, Mn, Mo, Se, V, Zn; non-essential: Ag, Al, As, Ba, Cd, Cr, Cs, Li, Ni, Pb, Rb, Sr, Ti, Tl, U) in whole soft tissues of Noah's Ark shell (Arca noae) were determined monthly during one year (March 2013-February 2014) at two sampling sites in the central part of the Eastern Adriatic Sea. Our aim was to detect the influence of reproductive cycle and changes in the environmental factors on the variabilities of TEs' contents. Higher concentrations of Pb, Ba, V, Mo, Mn and Fe were found at potentially contaminated site in Pašman channel, whereas higher concentrations of Tl, Ni, Li, Cr, Cd, Ti and Se were found at reference site in Nature Park Telašćica. Since several bioaccumulated TEs were associated to mean gonadal index, in TEs monitoring in A. noae, animal gonadal status has to be considered.

Trace elements and oxidative stress in the Ark shell Arca noae from a Mediterranean coastal lagoon (Bizerte lagoon, Tunisia): are there health risks associated with their consumption?

“…Comparing our results with those reported for A. noae from the Croatian (Cuculic´et al 2010, Ivankovic et al 2016, Milun et al 2016, Erk et al 2018 and Yugoslav Adriatic coasts (Ozretic´et al 1990), Zn, Cu, Ni, Cr, Pb, Cd, Fe, Mn, Se and Al concentrations were within the same range of concentrations (Table 5). Concentrations of these TE in A. noae flesh were similar to lower when compared with other bivalves from Bizerte lagoon, Tunisian and Mediterranean coasts (Kamel et al 2014;Richir and Gobert 2014;Boussoufa et al 2014;Joksimovic et al 2018;Prato et al 2019;Uluturhan et al 2019) (Table 5).…”

“…Recent studies on A. noae from the eastern and central Adriatic coasts (Croatia) have shown that this shellfish may accumulate various trace elements, polychlorinated biphenyls and organochlorine pesticides (Ivankovic et al 2016;Milun et al 2016;Erk et al 2018). Marine bivalves are known to pump large amounts of seawater and therefore come into contact with various chemicals in the water.…”

Oocyte analysis of species Arca noae Linnaeus, 1758 (Mollusca: Bivalvia) from Adriatic Sea

“…The present work aims to establish quantitative and qualitative parameters of oocyte sizes investigated in two Arca noae Linnaeus, 1758 (Bivalvia: Arcidae) populations along the Adriatic Sea of Croatia based on oocyte diameter analysis to study reproductive activity in females. According to defined developmental stages of the female gonads determined by Erk et al (2018) on the same samples, measurements of the oocyte diameters in one microscopic field were conducted. The results of oocyte diameter analysis and histological gonad examinations led us to propose a qualitative reproductive scale for help in accurate prediction of the spawning events important for potential commercial aquaculture operations.…”

“…Previous studies investigated Mediterranean and Adriatic Sea populations of this species. These studies include research on ecology (Marin & López Belluga 2005;Peharda & Morton 2006), functional morphology (Morton & Peharda 2008), population structure (Hrs-Brenko 1980;Bello & Paparella 2001;Peharda et al 2002aPeharda et al , 2003Peharda et al , 2009, reproduction (Peharda et al 2003Bello et al 2013;Ghribi et al 2017), aquaculture potential (Župan et al 2012Peharda et al 2013), nutritional composition (Ezgeta-Balić et al 2012Dupčić Radić et al 2014), growth and longevity of the species (Peharda et al 2002b(Peharda et al , 2003Puljas et al 2015), changes in heavy metal concentrations in the bivalve tissues during the reproductive cycle (Erk et al 2018) and the study of trace elements in shells (Kobelja et al 2016).…”

An Overview of Cadmium, Chromium, and Lead Content in Bivalves Consumed by the Community of Santa Rosa Island (Ecuador) and Its Health Risk Assessment

“…Bivalve mollusks are benthic organisms, used as sentinel species because of their long-life cycle and sedentary lifestyle (da Silveira Fiori et al, 2018). They allow pollution levels of marine ecosystems to be evaluated, providing integrated information over time on the presence of pollutants in the environment (Boening, 1999;Erk et al, 2018). Bivalves are characterized by their ability to filter water to feed (Ruiz et al, 2018).…”
