Seasonal accumulation of trace elements in native Mediterranean mussels (Mytilus galloprovincialis Lamarck, 1819) collected in the Calich Lagoon (Sardinia, Italy)

Occurrence of trace elements in Mediterranean mussels (<em>Mytilus galloprovincialis</em> Lamarck, 1819) from an experimental pilot farm in the Calich Lagoon (Sardinia, Italy)

“…According to previous studies reporting very low concentrations for Ag, Be, Bi, In and Tl in Mytilus spp. (Rodríguez-Hernández et al, 2019;Esposito et al, 2021), these trace elements scarcely or not investigated in mussels, were always below the method quantitation limit (LOQ) of 0.010 mg kg -1 in all the samples (Table 3).…”

“…The lagoon extends for 92 ha with a depth varying between about 0.5 and 1.5 m. It is connected with the Alghero Gulf through a natural channel (60-m wide and 2-m deep) hosting a medium-size shipyard and a tourist harbor. The lagoon receives freshwater from natural fluvial tributaries and an artificial channel (Pulina et al, 2017;Esposito et al, 2021). The Calich Lagoon suffers from high eutrophication due to urban, agricultural, and industrial activities (Fenza et al, 2014;Baralla et al, 2017;Bazzoni et al, 2018): its catchment area extends for about 42,000 ha, receiving water from several surrounding municipalities.…”

“…It is widely considered as one of the most suitable biological indicators of chemical pollution, due to its sedentary filter feeders' nature, wide geographical distribution, ease of sampling, and remarkably tolerance to chemical pollution (Emmanouil et al, 2008;Gupta and Singh, 2011;Waykar and Deshmukh, 2012;Zuykov et al, 2013) Lagoon is a typical Mediterranean lagoon of the northwest of Sardinia (Italy) located in an area of strong touristic impact (Baralla et al, 2017). In the late years, different authors have studied its ecology (Ielmini et al, 2014;Pulina et al, 2017Pulina et al, , 2018Bazzoni et al, 2018;Satta et al, 2020), proposed sustainable exploitation strategies (Chessa et al, 2005;Pais et al, 2006;Cannas et al, 2011) and highlighted the occurrence of bacteria, viruses, biotoxins and trace elements in native shellfish (Sedda et al, 2016;Baralla et al, 2017;Esposito et al, 2018;Bazzoni et al, 2019;Esposito et al, 2021). The main aims of the present…”

Environmental Stressors and Pathology of Marine Molluscs

“…Molluscs, particularly gastropods and bivalves, are suitable organisms (bioindicators) to assess the contamination levels of terrestrial, freshwater, and marine ecosystems worldwide [50][51][52][53][54]. This fact is related to some important features such as their widespread distribution, abundance, sedentary habits, body size, and, often, their ecological and/or economic relevance [55].…”

Determination of phytoplankton in water samples, algal biotoxins, microbiological parameters and microplastics in Mediterranean mussels (Mytilus galloprovincialis Lamarck, 1819) from an experimental pilot farm in the Calich Lagoon (Sardinia, Italy)

“…The lagoon extends for 92 ha with a depth varying between about 0.5 and 1.5 m. It is connected with the Alghero Gulf through a natural channel (60-m wide and 2-m deep) hosting a medium size shipyard and a tourist harbour. The lagoon receives freshwater from two natural fluvial tributaries and an artificial channel (Pulina et al, 2017;Esposito et al, 2021). The Calich Lagoon suffers of high eutrophication due to urban, agricultural, and industrial activities (Fenza et al, 2014;Bazzoni et al, 2018).…”
