原始语种摘要: This study evaluated the environmental risk assessment of sediment heavy metals of Nun River at Gbarantoru and Tombia town in Bayelsa state, Nigeria. Sediment samples were collected in triplicate from three locations (viz: Location A around oil and gas installations, B- Gbarantoru and C- Tombia town). The samples were dried, processed and heavy metals concentration was determined using atomic adsorption spectrometry. Heavy metals results in the sediment ranged from 0.005 – 0.012 mg/kg cadmium, 0.001 – 0.003 mg/kg chromium, 0.001 – 0.002 mg/kg cobalt, 0.001 – 0.032 mg/kg nickel, 0.007 – 0.017 mg/kg lead, 0.082 – 0.126 mg/kg zinc and 0.138 – 0.314 mg/kg iron. There was significant variation (P<0.05) among the different various locations. The heavy metals showed positive significant...
