Cadmium accumulation in tissues of Sarotherodon melanotheron (Rüppel, 1852) from the Aby Lagoon system in Côte d'Ivoire.

Cyrille YD, Victor K, Sanogo TA, Boukary S, Joseph W - Int J Environ Res Public Health (2012)

Bottom Line: The organisms were grouped into two composite samples (juvenile and adult) of five individuals.Fish muscle appeared to have a significantly higher tendency to accumulate cadmium (1.19-5.18 µg/g dw) while gills and livers had minimum concentrations (0.07-1.32 and 0.12-1.25 µg/g dw).This study has revealed that the concentrations of Cd in Sarotherodon melanotheron muscle tissue were above the maximum acceptable concentrations for human consumption, thus precautions need to be taken in order to prevent future contamination.

ABSTRACT
This study assessed the concentrations of cadmium in the gills, livers and muscles of a commercially important tilapia fish (Sarotherodon melanotheron) from Aby Lagoon in Adiaké, Côte d'Ivoire, between January and December, 2010. The organisms were grouped into two composite samples (juvenile and adult) of five individuals. Levels of cadmium were determined in tissues using Perkin-Elmer (AAnalyst 200) Atomic Absorption Spectrophotometry (AAS) after a digestion method. Fish muscle appeared to have a significantly higher tendency to accumulate cadmium (1.19-5.18 µg/g dw) while gills and livers had minimum concentrations (0.07-1.32 and 0.12-1.25 µg/g dw). This study has revealed that the concentrations of Cd in Sarotherodon melanotheron muscle tissue were above the maximum acceptable concentrations for human consumption, thus precautions need to be taken in order to prevent future contamination.

ijerph-09-00821-f001: Map showing Aby lagoon and sampling site.

Mentions: The study was carried out in the Côte d’Ivoire’s rural Aby Lagoon system, located between longitudes 2°51'N and 3°21'N and latitudes 5°05'W and 5°22'W. Two main tributaries (Bia and Tanoe) are escape routes from anthropogenic and mining operations within its watershed in Côte d’Ivoire and Ghana [8]. Fish samples were collected at Adiake station during the three main seasons (January to April, May to August and September to December) (Figure 1).
