Loads of trace metals in Biota, Sediment and Water of Southern I jaw Creeks of Bayelsa State, Nigeria

Abstract

The concentrations of four trace metals Fe, Mn, Pb, and Cd were determined in water snail (Ancylus fluviatilis), sediments and water of five creeks in Bayelsa state. Two categories of the aquatic organisms (Ancylus fluviatilis) were collected from the creeks. The samples were analyzed for the metals with Atomic Absorption Spectrophotometer model 206 A. The results revealed that in category A, the levels of the metals occurred in the following range in mg/kg Fe (101.69 – 135.4), Mn (30 – 47.73), Cd (0.001 – 0.005) and Pb (4.05 – 8.06). In category B Fe (105.34 – 173.06), Mn (18.11 – 39.12), Cd (
