The area is located in the tropical rain forest, with eight 116 months of rainy season ...
This study investigated the concentrations of cadmium (Cd), lead (Pb) and zinc (Zn) in soil and vegetables, and the associated health risk of ingesting vegetables from Amaonye-Ishiagu farming zone ...
Geo-hazard associated with Pb-Zn mining activity in Ishiagu over the past 40 years is of great concern to environmentalists and the community. Discharge of mine waste to farm lands and consequent drainage to nearby stream is environmental crime that calls for investigation in Ishiagu and in other communities along the Benue Trough of Nigeria. ...
To extend mining activities in Ishiagu, a better understanding and reconsideration of the continuation of exposed ores is necessary. Having confirmed the local mining in the area to be ... As Ishiagu Pb-Zn deposits represent an integral part of Benue Trough sedimentary basin evolution, strategies for exploring them must take into account the ...
