Environmental Risks of Mining

When companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. As dust, these minerals (such as the asbestos-like mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as "Black Lung" (Paul & Campbell, 2011).

The Mining effects and green solutions Follow Green Living

Health problems due to mining: 1) The toxicity of metal can cause problems due to mercury, fluorine and also arsenic. These metals enter the food chain and affect all the animals in suit. 2) Mining also cause lung defects like Pneumoconiosis which is due to the inhalation of coal and other dust particles in the process of mining.
