Relationship between trace element concentration and condition index in bivalves from lagoons in Ghana

The study investigated the seasonal relationship between the Condition Index (CI) and concentrations of six trace metals in the tissues of three bivalves: Crassostrea tulipa (n = 275), Anadara (Senilia) senilis (n = 310) from two 'open' lagoons (Benya and Ningo), a 'closed' lagoon (Sakumo), and Perna perna (n = 155) from rocky shores adjacent to Benya and Sakumo. These bivalves were analyzed for their...

Valorization of mining waste through fertilizer formulation: substitution of phosphoric acid by slimes and characterization of the obtained fertilizers

This study aims to valorize the slimes (<40 µm and rich in P2O5) generated during the processing of phosphate ore from Taiba by formulating complex compound fertilizers using these wastes as a source of P2O5 through the progressive substitution of phosphoric acid. Following a complete characterization of the raw material using atomic absorption spectrophotometry and X-ray fluorescence, NPK complex fertilizers...
