摘要：Zinc (Zn) content was evaluated of the arable soils in the vicinity of mining and dumping sites in Nigeria. Its content the arable soils assayed by means of Atomic Absorption Spectrophotometry (AAS) ranged from 48.3 to 280.4 mg/kg. The Enrichment Factor (EF) calculated by using manganese as a crustal reference element fell within a range of 16.3-161.2. The mean values of the enrichment factor of 59.41 classified the soil as extremely high enrichment with zinc. Anthropogenic activities contribute significantly to the elevated level of zinc in the studied areas.
