AB  - Agricultural activities are taking place on/or around abandoned tin mine areas on the Jos Plateau, Nigeria. Agricultural practices on mine soils intensify contamination of soils by heavy metals and pesticide residues and the challenging problem to produce food safe for human or animal consumption.
