- Five marine species from different trophic levels were analyzed for trace elements.
- Differences in element concentrations and bioaccumulation were found between species.
- Transfer factors to biota from water were greater than those from sediments.
- Spatial variation in element concentrations and bioaccumulation were recorded.
- Cd and Pb concentration in biota were below the EU limit values for edible seafood.
Concentrations of 11 elements were quantified in five marine species from different trophic levels of a food web (algae, mussel, shrimp and fish), representative for shallow Senegalese coastal waters, and including species of commercial importance. Significant differences in element concentrations and bioaccumulation were demonstrated, revealing the utility of employing a suite of organisms as bioindicators to monitor metal contamination in coastal areas. There was no clear seasonal pattern in concentration of elements, however inter-site differences were observed. Calculations of transfer factors for all the studied elements showed that transfer factors from water were greater than those from sediments. For shrimp and mussel, the concentrations of Pb and Cd were below the EU's maximum level for human consumption, however high concentrations of arsenic in shrimp were recorded at all sites.
