Dynamics and behavior of trace elements in marine waters

The management of aquatic resources worldwide is becoming increasingly problematic in the so-called Anthropocene era. With the aim of characterizing and studying the biogeochemical processes taking place in the lagoon waters of C te d'Ivoire, this study was carried out on the water, sediment and sediment core matrices of the Aby lagoon (C te d'Ivoire), using conventional methods adapted to modern times and the African region. The results of this study showed that the water and sediment were contaminated with mercury, but also that the water could be carcinogenic. In addition, index characterization showed that the sources of these trace elements were anthropogenic and that trace element dynamics were evolving with atypical marine sedimentation.
