Abstract

The study was conducted to determine the level of concentration of heavy metals and physicochemical properties of the soils of the study area. The levels of pH varied slightly between 5.30 (ETAK IDIM) and 5.44(OKPSON 1).The concentration of the available Phosphorus varied from 2.08ppm(OKPSON 1) to 2.81ppm (ATAI 1). The Total Hydrocarbon Content varied from 4034.12 mg/kg (ITAK IDIM UKPA) to 4904.71 mg/kg (NEW BARRACK). The textural class of the soils was generally sand. The silt particles had range from 0.56% (ETAK IDIM and ATAI 11) to 2.00% (ITAK IBANG), The clay minimum value (1.00%) was obtained from ATAI 1 and maximum value of 3.00% was obtained from ITAK IBANG, OKPSON 1 and ATAI 11. The sand particles ranged from 95% (ITAK IBANG) to 98% (ATAI 1). While the concentration of Ammonium ion varied from 14.65ppmN (OKPSON 1) to 32.50ppmN (NEW BARRACK). The concentration of heavy metals showed that Pb varied between 12.41mg/kg (ETO ESEK) and 23.24mg/kg (NEW BARRACK); Cu ranged from 5.10mg/kg (ETO ESEK) to 18.12mg/kg (OKPSON 1);Cr levels ranged from 15.17mg/kg (OKPSON 1) to 23.00mg/kg (ETO ESEK); Ni varied from 1.00mg/kg (ETO ESEK) to 26.14mg/ kg (ATAI 1).
