标题:Concentration of heavy metals and its risk assessments on Pseudotolithus senegalensis, Sciaenops ocellatus and Chloroscombrus chrysurus smoked on different ovens
摘要:AbstractThis study sought to investigate the concentration of heavy metals and risk assessment in the fresh and smoked fish tissues (Muscles, gills and bones) ofPseudotolithus senegalensis, Sciaenops ocellatus, andChloroscombrus chrysurus. Pseudotolithus senegalensis, Sciaenops ocellatus,andChloroscombrus chrysuruswere caught off the coast of Jamestown beach in Accra and treated as fresh, smoked, unwashed and washed. Smoking was done onAhotor, Chorkor,and Oil drum ovens, and analyzed for heavy metals using Atomic Absorption Spectrophotometry. Fish tissues ofPseudolithus senegalensis, Sciaenops ocellatus, andChloroscombrus chrysurussmoked onAhotoroven respectively followed a different pattern of heavy metal concentration as Muscles > Bones > Gills; Bones > Gills > Muscles and Gills > Bones > Muscles whereas smoked fish tissues ofPseudolithus senegalensis, Sciaenops ocellatus, andChloroscombrus chrysuruson Chorkor and Oil drum oven showed a similar pattern as Gills > Bones > Muscles. Studied Fish species showed higher levels of heavy metals concentration onAhotorfollowed by Oil drum andChorkorovens. The concentration of heavy metals inPseudotolithus senegalensis, Sciaenops ocellatus,andChloroscombrus chrysuruswas reduced after washing. All EDI values recorded exceeded the permissible limit but THQ and TTHQ values were <1, indicating a lower health risk hazard when smoked fish from these species is consumed.
