Impacts of Manganese Mining Activity on the

2012-11-4  The mining district of Molango in the Hidalgo State, Mexico, possesses one of the largest deposits of manganese (Mn) ore in the world. This research assessed the impacts of Mn mining activity on the environment, particularly the interactions among soil, plants, and arbuscular mycorrhiza (AM) at a location under the influence of an open Mn mine.

Environmental effects of manganese-Metalpedia

Manganese that comes from human sources can also enter surface water, groundwater and sewage water. Through the application of manganese pesticides, manganese will enter soil. For animals, manganese is an essential component of over 36 enzymes that are used for their carbohydrate, protein and fat metabolism.
