Decades of tin extraction on the Jos Plateau have left behind heavily reworked ground, including open pits, spoil heaps and slurry deposits, much of which has gradually been absorbed back into local farming. This paper re-examines a field investigation of that reclamation process...

Heavy-metal Contamination of Soils and Water in the Apkai and Umusedege Oil-field Communities, Ndokwa East and Ndokwa West, Delta State, Nigeria

Sanda Yusuf Sadau, Ishaya Iliyasu, M. Alpha, Muhammad Lawal, Mubarak Mu’azu Gambo, Gada Sunday Samson & Oyadiran Wuyi Jonathan · Physical Science International Journal · 2026

Petroleum exploration and production can introduce potentially toxic metals into the soils and water bodies of host communities, with consequences for both ecosystem integrity and human exposure. This study assessed the concentrations and distribution of ten heavy metals: Ni, Cr,...

Geochemical Fractionation, Mobility and Environmental Risk of Lead, Cadmium and Zinc in Agricultural Soils from an Abandoned Mining Area in Jos-South, Nigeria

Sanda Yusuf Sadau, Ishaya Iliyasu, M. Ndawashi, M. Alpha, Sunday H. Sarki, Tina Abimbola A. & Oyadiran Wuyi Jonathan · Physical Science International Journal · 2026

The total amount of a potentially toxic element in soil, on its own, provides limited information about its mobility or bioavailability. This paper re-examines the geochemical partitioning, extractability and environmental status of lead (Pb), cadmium (Cd) and zinc (Zn) in agricu...

Geochemical Fractionation, Stability and Potential Mobility of Heavy Metals in Soils from Oil-field Communities of Delta State, Nigeria

Sanda Yusuf Sadau, Ishaya Iliyasu, Sunday Sarki Habila, A. A. Adelowo, Yusuf Umar, Gada Sunday Samson & A. Tina Abimbola · Asian Journal of Applied Chemistry Research · 2026

The total concentration of a heavy metal in soil provides limited information about its environmental behaviour, since mobility and potential bioavailability depend strongly on the geochemical phase with which the metal is associated. This study investigated the fractionation, st...

Human Health Risk Assessment of Heavy-metal Exposure in Soil and Water from Oil-producing Communities of Delta State, Nigeria: An Audited Reassessment

Sanda Yusuf Sadau, N. Rabiu, N. N. Garba, Suleiman Bello, Ishaya Iliyasu & Tina Abimbola Adeniji · Asian Journal of Physical and Chemical Sciences · 2026

Heavy-metal contamination in oil-producing environments may create human-health concerns through ingestion, inhalation and dermal exposure. This study reassessed non-carcinogenic and carcinogenic risks associated with Ni, Cr, Cu, Co, Pb, Cd, Fe, Mn, As and Zn in soil and water fr...
