  Environmental Quality of the Boula-Nuasahi Chromite Mine Area in India ...

  20101224 · Chromite mining can create hostile conditions for organisms in the surrounding environment. Overburden soil and mine water samples were collected and analyzed for their microbial diversity, nutrient content, and water quality at the Boula-Nuasahi Mine. Most of the water parameters that were measured exceed national/international …
