During its different stages numerous impacts are generated to the environment. The activities in the region have generated a great amount of mining residues, which have caused severe pollution and health effects in both human population and biotic components. The aim of this paper was to assess the impact of mining activities ...Heavy Metals in Tailings,Soils and Vegetation of an ...Lead, copper, and zinc have been specifically considered. Chemical analyses have been achieved using ICP-AES. Results showed significant concentration of Pb in mining residues and vegetation that colonize the surrounding area. Concentrations of the three heavy metals in soil and plant samples were minimal at 1 km from the piles of tailings.

Effect of coal mining on vegetation disturbance and ...

 · Vegetation is an important part of the environment but may be subjected to disturbance in areas close to coal mines. This results in a slowing of the rate of biomass growth, which is caused by fading of vegetation. Simultaneously, carbon stored in vegetation is constantly released, weakening vegetation ability to act as a carbon sink. Indirect release of carbon during coal mining processes is ...Groundwater controls on vegetation composition and .Vegetation composition in this environment is influenced by both (1) oxygen stress that occurs when portions of the root zone are saturated and anaerobic conditions limit root respiration and (2) water stress that occurs when the water table drops and the rootAppendix C - Potential Threats to the Ecological ... · Mining (Caliche) Oil/Gas development Activities that alter structure, composition and process: - Removal of vegetation (Roads and pads can lead to loss of natural soil productivity) - Limited extent at landscape scale - Fragmentation Activities that alter structure, composition and process:
