摘要：
The concentrations of heavy metals (mg/g) Pb, Ni, Cu, Cr, Fe, Co, Cd, and Hg in the tissues of young and adult toads exposed to petroleum-polluted environment were determined in order to assess the impact of petroleum-processing activities in Ekpan. The data showed that the levels of these Metals ranged between 0.15-1.18 and 0.10-0.48 in young and adult toads respectively. The heavy metals concentrations reported for the young toads have an abundance trend in the order of Pb > Fe > Ni > Cr > Cu > Co > Cd > Hg, while those of the adult toads are in the order of Pb > Fe > Cr > Ni > Cu > Cd > Hg > Co. The control analysis was carried out in a non-oil polluted area (Obiaruku) and the values served as base line values for the study. © 2008 Springer Science+Business Media, LLC.
