Comparative study of the bioaccumulation and elimination of trace metals (Cd, Pb, Zn, Mn and Fe) in the digestive gland, gills and muscle of bivalve Pinna nobilis during a field transplant experiment

First data on three bivalve species exposed to an intra-harbour polymetallic contamination (La Rochelle, France)

“…Statistic correlation tests were carried out to investigate relationships between inorganic pollutants and specific activity of biomarkers in order to determine the best bioindicator species for longer-term studies in the La Rochelle harbour. Indeed, it now seems necessary to bridge both, bioaccumulation and enzymatic data, which have not been covered together in previous reports on bivalve species in harbours (Caro et al, 2015;Hussein and Khaled, 2014;Walker and MacAskill, 2014;Jebali et al, 2014;Conte et al, 2015;Jitar et al, 2015;Walker and Grant, 2015).…”

Bioaccumulation patterns, element partitioning and biochemical performance of Venerupis corrugata from a low contaminated system

“…Among contaminants, inorganic compounds such as metals and metalloids, even at low concentration, may contribute to the estuaries deterioration affecting the organisms inhabiting these areas (Coelho et al, 2006;El-Nemr et al, 2012), particularly benthic macrofauna. Bivalves, which are mostly filter-feeders contacting directly with contaminated water and sediment, are greatly affected by these contaminants (Pellerin and Amiard, 2009;Al-Subiai et al, 2011;Moschino et al, 2012;Jebali et al, 2014). Furthermore, metals and metalloids can be accumulated in lower trophic levels and biomagnified along the food chains (Figueira et al, 2011).…”

“…In the last years, a large number of marine bivalves, such as Venerupis philippinarum (Sfriso et al, 2008;Moschino et al, 2012;Matozzo et al, 2012;Wang et al, 2012), Cerastoderma edule (Bergayou et al, 2009;Freitas et al, 2012b), V. decussata (Cravo et al, 2012;Matozzo et al, 2012;El-Nemr et al, 2012), Pinctada radiata, Saccostrea cucullata, Circentia callipyga, Pinna muricata (Mora et al, 2004), Pinna nobilis (Jebali et al, 2014), Mytilus edulis (Pellerin and Amiard, 2009), Mya arenaria (Pellerin and Amiard, 2009;Al-Subiai et al, 2011), Perna viridis (Jena et al, 2009), and Venerupis corrugata (Fern andez et al, 2013) have been used as indicators for the presence of toxic substances in the marine environment.…”

The Alteration Tissue Structure of Digestive diverticulum of Anodonta woodiana Induced by Lead

“…In the previous study, Mussel was used to evaluate In Situ metal contamination in wastewater effluent and in aquatic ecosystems [10,11]. The concentration metal in the tissue of mussel was increased concomitantly with the elevating of metal absorption or uptake and it showed the various metal bioaccumulation levels in different tissues of mussel [12,13].…”
