Abstract

Widespread artisanal, alongside small-scale mining operations are currently increasing in intensity in Nigeria. These activities are causing immeasurable damage to the environment and populations that live in the vicinity of these mine fields. The discharges of Potentially Harmful Elements (PHEs) from the exposed mine-out /mineral processing sites and their subsequent remobilization into the soils, and natural water bodies constitute serious human health problems. A study aiming at understanding the extent by which these elements contaminate the soils at the vicinity of the mining operations was conducted. This study also sought to identify the possible effects on human health and how it can be best mitigated. Geochemical results suggest that the discharges of PHEs from the mining/mineral ore processing operations have contributed significantly to the enrichment of these elements in the surrounding environment, thereby contaminating drinking water sources, food crops, and are disposed to subsequent entry into the human body through the food chain. Many of the mining communities make their living from subsistence farming, growing food from the surroundings, and obtaining drinking water from nearby surface and sub-surface water resources. The direct or indirect exposure of the human population to PHEs constitutes a potential risk to human health if not monitored and abated. Reports of in-vitro bio-accessibility tests show that less than 50% of bio available heavy metal contaminants in ingested soil are bio accessible during digestion process. Thus, there is need for the reduction of bio-available PHE in the soil by ensuring that mining operations generally are done in a manner that will secure a quality of environment adequate for good health and well-being of the communities around.
