Where In Mexico Is Manganese Mined

To investigate this, we chose a region of rural Mexico where Mn has been extensively mined for the past 50 years (see Study site), where elevated levels of Mn in the soil, waterways, vegetation, and atmosphere have been recorded (SolísVivanco et al. 2009;JuárezSantillán et al. 2010), and where significant deficits in motor and cognitive performance have been reported (Rodríguez .
