Geochemical study of heavy metals in samples from dumpsites at Onitsha, Anambra Basin, Southeastern Nigeria

Year: 2024

Type: article

Abstract: Core (0-60cm) samples were collected from selected dumpsites at Onitsha and control site at Awka, Nigeria. Physiochemical parameters (particle size distribution, cation exchange capacity (CEC), pH, Organic Matter (OM in %)) and heavy metals (Lead (Pb), Copper (Cu), Zinc (Zn), Chromium (Cr), Nickel (Ni), Aluminium (Al), Cobalt (Co), Molybdenium (Mo), Cadmium (Cd), Manganese (Mn) and Silicon (Si)) were analyzed using standard methods. The result of the physiochemical analysis shows that the samples were generally sandy with acidic pH values (4.89-6.24); OM ranged from 5.693-27.71%; CEC ranged from 0.072-0.62(Cmol/kg). Comparatively, DS 5 (Obosi) has the highest levels of these heavy metals followed by DS 2 (Woliwo). The order is Bida < Okpoko
