Detailed introduction

Environmental Impacts of Mining and Smelting

We visited gold mines, ore processing sites and lead mines where we collected soil and water samples and completed a hazard evaluation for each site. We also worked with the Nigerian Ministry of Mines and Steel Development (MMSD) in coordination with other government agencies to conduct a three-day training session to increase the capacity within government agencies to evaluate hazards in ASM.
