Speciation and bioavailability of potentially toxic element in soils and sediments of mining areas in Meiganga Adamawa plateau (Cameroon).

Contamination by potentially toxic elements (PTEs) is a major environmental concern, especially in mining sites, given the often-increasing concentrations in soil and sediments. Under certain conditions, such contamination may expand beyond the mining area, posing risks to human health. This study investigates the environmental hazard associated with PTEs in soils and river sediments from the Meiganga gold district by evaluating their speciation and mobility.
