“…This destruction of the environment negatively impacts the health of the miners and people living within the neighbourhood. More so, unregulated artisanal mining in Nigeria increases the severity of the risks involved as gold ores are often extracted, handled, stored and transported without precautions (Oke et al, 2020).…”

The human health risk assessment conducted by Oke et al (2020) found that the concentration of chromium was beyond safe levels in the Epe gold mining area and contributed to increased cancer risks for people with prolonged exposure.

Though the gold mining industry potentially generates employment and increases Nigeria's foreign exchange, the crude practices of artisanal miners often exacerbate environmental degradation and health hazards. Hence, humans face health risks when excessively exposed to the heavy metals released during gold mineralization. This study, therefore, adopts a descriptive approach towards suggesting a comprehensive economic evaluation and risk analysis for managing the impact of gold mining industry sustainably and bearing in mind people's health that should equally be managed in a healthy and sustainable manner. A review of existing Environment-Health Risk Assessment (EHRA) studies on gold mining areas in Nigeria reveals that the estimated risk quotients are generally above recommended limits consequent upon inadequate enforcement of mining precautions. This study, therefore, argues that incorporating EHRA studies and considering economic costs and benefits of mining could provide an objective benchmark for managing various estimated health risk quotients and returns from more gold mining. For Nigeria's, harnessing opportunities in the gold mining industry requires interdisciplinary drive that seeks to incorporate environmental-health risks into optimization of gold mining industry. Appropriate policy interventions will be expedient for gold mining industry to be less harmful and not constitute direct threat to sustainable development in Nigeria.

“…It accounts for both the individual concentrations of HM and their potential combined effects. The mCd index provides valuable information about the pollution status of an ecosystem, helping to assess the cumulative effects of various heavy metals on the environment (Oke et al 2020). The mCd index is calculated using the following formula in Eq.…”

Given increasing concerns about the environmental impact of heavy metal pollution, assessing the level of contamination in floodplain suspended sediments is an important task. Effective environmental management and the preservation of an ecosystem depend on understanding existing pollution levels and potential concerns in the future. For this reason, floodplain-suspended sediments from major industrialized cities in Southeast Nigeria were sampled and analyzed for heavy metal contents. The investigation was conducted to evaluate the immediate and long-term bioavailability and pollution status of heavy metals in receptor organisms. A five-step sequential extraction procedure was adopted to fractionate iron, manganese, copper, zinc, nickel, lead, cadmium, and chromium to determine the geochemical phases in which they were distributed. Generally, the heavy metals were partitioned in the following order: residual > > oxidizable > carbonate > reducible > exchangeable. This indicates that a significant portion of the metals was tightly bound to the soil matrix, rendering them not readily bioavailable to the biota, except over an extended period. The levels of heavy metals, except for lead and cadmium in specific areas, were below the saturation point in terms of their bioavailability. Furthermore, the pollution assessment indices, such as the geo-accumulation index, reflected high levels of cadmium, copper, and lead contamination. This suggests a potential ecotoxicological risk to organisms near the sampling sites. The sites were classified as moderate and high risk in terms of immediate and future risk assessment, respectively. Proper cleaning methods and potential site reclamation are imperative to minimize or contain these heavy metals in stable forms within urban areas to prevent bioaccumulation.
