“…Our finding coincided with the values obtained by Kayhan et al [13] in the seawater of Tuzla Shipyard area of Turkey. The seawater salinity was influenced by the freshwater influx coming from the neighboring rivers during the rainy periods [14,15]. Water temperature began to rise in February, and the peak temperature of 20.67 ± 0.153 °C was recorded in August.…”

The monthly variations in metal concentration of Cadmium (Cd), Zinc (Zn) and Chromium (Cr) were determined in tissues of Mytilus galloprovincialis and seawater obtained from the mussel farm installed along the Al Hoceima coasts, during the sampling period of 2018. The heavy metals encountered in the bivalves were higher than those observed in their environment with a decreasing order of Zn > Cr > Cd. The results also showed a decreasing trend for the metals studied during the summer sampling campaign. The maximum values were obtained during the wet periods. The monthly variations in trace metals observed in the mussel tissues were due to environmental parameters and the physiological state of the bivalves. Our results revealed that the average concentrations of pollutants found in M. galloprovincialis were below the limits allowed by the Food and Agriculture Organization of the United Nations (FAO) which are 2.0, 1000 and 1.0 mg/kg, for Cd, Zn and Cr, respectively in molluscan shellfish for human consumption. Therefore, the trace elements present in the tissues of Al Hoceima shore mussels do not represent a risk to human health associated with their consumption, even during the period of their maximum bioaccumulation. Our work highlights the potential use of Mytilus galloprovincialis in the Biomonitoring of metallic pollutants in this region of the northern Moroccan coasts.

“…Mussels have also been extensively applied to environmental monitoring programs [11]. Many Mytilidae mussels have been employed as biomonitors throughout the Indo-Pacific region for assessing chemical and heavy metal pollutants [12, 13]. They are useful due to their widespread distribution and sedentary life style, and they grow enough tissue for studying the accumulation of heavy metals.…”

The Byssus, which is derived from the foot gland of mussels, has been proved to bind heavy metals effectively, but few studies have focused on the molecular mechanisms behind the accumulation of heavy metals by the byssus. In this study, we integrated high-throughput transcriptome and proteome sequencing to construct a comprehensive protein database for the byssus of Chinese green mussel ( Perna viridis ), aiming at providing novel insights into the molecular mechanisms by which the byssus binds to heavy metals. Illumina transcriptome sequencing generated a total of 55,670,668 reads. After filtration, we obtained 53,047,718 clean reads and subjected them to de novo assembly using Trinity software. Finally, we annotated 73,264 unigenes and predicted a total of 34,298 protein coding sequences. Moreover, byssal samples were analyzed by proteome sequencing, with the translated protein database from the foot transcriptome as the reference for further prediction of byssal proteins. We eventually determined 187 protein sequences in the byssus, of which 181 proteins are reported for the first time. Interestingly, we observed that many of these byssal proteins are rich in histidine or cysteine residues, which may contribute to the byssal accumulation of heavy metals. Finally, we picked one representative protein, Pvfp-5-1, for recombinant protein synthesis and experimental verification of its efficient binding to cadmium (Cd 2+ ) ions.

“…Los periodos de lluvias aumentan el caudal del río Neverí, lo cual aunado a cambios en la hidrodinámica del mar Caribe, pueden contribuir a la disponibilidad de metales pesados de manera estacional. En otras localidades se ha demostrado la incidencia de los cambios ambientales de las temporadas secas y lluviosas sobre la variación del contenido de metales pesados (Cd, Pb) en distintas especies de bivalvos (Frías-Espericueta et al 2008, Pinto et al 2014.…”
