<b>Mobility and Distribution of Some Selected Trace Metals in Soil from Dumpsite in Lafia, Nasarawa State</b> Mobility and distribution of some selected trace metal was carried out using Tessier et al 1979sequential extraction method and the results obtained shows from dumpsite A, samples taken from 0 – 5cm the result ranges from 0.56 – 21.56 , 0.34 – 40.66 , 1.34 – 29.18 , 0.06 to 45.91 and 0.37 – 12.95 for the exchangeable, Fe – Mn oxide, organic carbonate and residual fractions respectively. For the samples taken from 10 – 15cm at dumpsite A, the results of the fractions are 0.42 – 13.63 , 0.03 – 18.48 , 1.01 – 25.34 , 0.03 – 35.19 and 0.27 – 9.31 for exchangeable, Fe – Mn oxide, organic, carbonate and residual fractions. The results of dumpsite Bare 0.48 27.36 , 0.28 40.07 , 2.93 31.15 , 3.87 42.50 and 0.84 30.67 for exchangeable, Fe Mn oxide, Organic, carbonate and residual fractions for sample taken from 0 5cm while for samples taken from 10 – 15cm the results show 0.32 – 36.38 , 0.23 – 16.49 , 0.53 – 15.83 , 1.53 – 34.88 and 0.04 – 5.27 for exchangeable Fe – Mn oxide, carbonate and residual fractions respectively. The dumpsite C has the concentration of the various fractions ranging from 0.25 – 18.34 , 2.73 to 15.58, 4.02 – 23.28 , 0.07 – 45.25 and 1.57 – 37.43 for exchangeable, Fe – Mn oxide, organic, carbonate and residual for samples taken from 0 – 5cm while for samples taken between 10 – 15cm the concentrations are 0.42 – 12 .62 0.80 – 11.59 , 2.16 – 17.33 , 9.86 – 34.48 and 0.99 – 32.99 respectively.
