Assessment of Heavy Metals and Polycyclic Aromatic Hydrocarbons in Agricultural Soils around Kubanni Bridge area, Zaria, Kaduna State, Nigeria

The level of heavy metals and polycyclic aromatic hydrocarbons (PAH) were determined from agricultural soil collected in Kubanni area Zaria using standard methods. result mean±SD the five study locations; (KP1- KP3) ranges 4.05±0.18-1.25±0.32 for Lead, 4.43±0.11-0.03±0.01 Cadmium,4.30±0.14 - 0.13±0.08 Chromium, 3.32±0.25-1.03±0.13 copper. And 1.80±0.01- 0.02±0.01 Zinc. results persistent organic pollutants locations KP1- KP3 showed mean range (±SD) concentrations from7.08±0.02-0.13±0.01 (naphthalene), 7.00±0.08 (anthracene) 7.31±0.21 (phenanthrene). There was appreciable number PAH even though it found to be below permissible set by United State Environmental Protection Agency (USEPA) National Standards Regulations Enforcement (NESREA) most locations. is tendency these residues accumulate into crops grown studied area, which can constitute serious health risk.
