原始语种摘要: The level and tissue bioconcentration V,Mn,Fe,Co,Ni,Cu,Zn,As,Se,Mo,Ag,Cd and Pb were determined in the viscera and shell of the freshwater snail, Melanoides tuberculata in the upstream and downstream of Alaro stream, South West Nigeria. Trace metal concentrations in snail and sediment samples collected from six stations were measured using an inductively coupled plasma-mass spectrometry (ICP-MS). The mean trace metal concentrations (ppm) of V,Mn,Fe,Co,Ni,Cu,Zn,As,Se,Mo,Ag,Cd and Pb in the snail were estimated to be 2.10-3.26,28.31-33.32,1668.21-2398.43,1.75-3.98,6.18-8.12,33.86-89.23,12.10-66.35,0.78-0.96,9.86-11.35,1.44-1.73,1.98-2.33,2.88-3.22 and 10.12-14.12 respectively. The study shows that M. tuberculata is capable of bioconcentrating trace metals in magnified quantity than that...
