Causes and Effects of Mining on Human Health and the,

The mining industry generates wastes containing high concentrations of metals and metalloids which are highly toxic to the environment.Moreover, the continued use of the traditional methods of mining intensifies the emission of toxic and non-ecofriendly products.This article details the causes and effects of mining on human health and the environment.How can metal mining impact the environment? | American,,Material adapted from: Hudson, T.L, Fox, F.D., and Plumlee, G.S. 1999. Metal Mining and the Environment, p. 7,20-27,31-35,38-39. Published by the American Geosciences Institute Environmental Awareness Series. Modern mining operations actively strive to mitigate potential environmental consequences of extracting metals, and such operations are strictly regulated in the United6 Potential Environmental Effects of Uranium Mining,,The human health effects of airborne particulate exposures are described in Chapter 5; in this chapter, the committee describes the potential for off-site transmission of contaminants and air pollution effects on the environment at modern uranium mining and processing facilities.

Gold mining can significantly alter the natural environment.Copper Sulfate Technical Fact Sheet,The U.S. EPA determined the chronic NOAEL for reproductive effects was 11.7 mg/kg body weight copper and the chronic LOAEL for reproductive effects was 15.1 mg/kg body weight of copper based on a study of mink. 3; Adult chickens were exposed to copper sulfate by gavage at concentrations of 200, 600, 800, 1200, and 1600 mg/kg body weight.Pollution - Wikipedia,Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.Pollution is often classed as point source or nonpoint source pollution.

Uses of Copper | Supply, Demand, Production, Resources

Although many historic mining operations were not required to conduct their mining activities in ways that would reduce their impact on the environment, current Federal and State regulations do require that mining operations use environmentally sound practices to minimize the effects of mineral development on human and ecosystem health.,,
