Heavy metal concentrations in molluscs from the Senegal coast

Spatial and seasonal variations of trace elements concentrations in liver and muscle of round Sardinelle (Sardinella aurita) and Senegalese sole (Solea senegalensis) along the Senegalese coast

“…None of the sole or sardinella had a Cd concentration exceeding this value. These results differ with those for molluscs where the threshold limit for Cd was exceeded at other locations along the Senegal coast (Sidoumou et al, 2006;Bodin et al, 2013). The Pb concentrations in muscle samples in our study ranged from <0.001 to 0.014 mg kg À1 ww with a mean ± sd of 0.006 ± 0.002 mg kg À1 ww ( Table 3).…”

“…Data from the literature generally reported cadmium concentrations in the liver of various species to be less than 10 mg kg À1 dw, and more often less than 1 mg kg À1 (Henry et al, 2004;Velusamy et al, 2014;Perugini et al, 2014). High levels of cadmium have already been found in the livers of different fish species and in molluscs from West African coastal areas such as the Mauritanian waters (Rom eo et al, 1999;Sidoumou et al, 2005) or Senegalese coast (Sidoumou et al, 2006;Bodin et al, 2013). These levels of Cd were attributed to natural origins, such as the upwelling of deep waters which takes place along the Western Atlantic coast (Rom eo et al, 1999).…”

Assessment of trace metals contamination level, bioavailability and toxicity in sediments from Dakar coast and Saint Louis estuary in Senegal, West Africa

“…Some Western Africa estuarine habitats have been seriously degraded for the last 30 years by climate changes causing severe droughts with reduction of freshwater flow, combined with the increase in domestic and industrial effluents (Bouvy et al, 2008). In Senegal, very few studies (Biney et al, 1994;Sidoumou et al, 2006;Diop et al, 2012) concern heavy metal concentrations in aquatic environment. The Dakar coast is located in an industrialised and populated area.…”

Concentrations of Metals in Tissues of Cockle Anadara granosa (Linnaeus, 1758) from East Java Coast, Indonesia, and Potential Risks to Human Health

“…Besides having an important economic value, bivalves have been well established as biomonitoring organisms to assess metal pollution due to their capability to accumulate metals within their tissues [7]. The use of bivalves as bioindicators for monitoring the concentration of heavy metals has been conducted in many areas in the world [8][9][10][11][12][13][14][15][16]. Due to their widespread distribution, cockles therefore can be used as biomonitoring organism for comparative study.…”
