Environmental Consequences of Open Pit Mining Blogger
Mar 14, 2012Environmental Consequences of Open Pit Mining An open pit mine is a type of excavation where surface and subsurface materials (soil and rock) are removed, typically through use of explosives and mechanical mining and hauling equipment, to gain access to commercially valuable ores or other buried natural resources, including coal and gemstones
Cadmium An Illusive Presence Dartmouth Toxic Metals
But true scrutiny over the toxic effects of cadmium exposure did not come until 1945 when the fall-out from chronic cadmium poisoning incidents in Japan caused an uproar over the metal. In the prefecture of Toyama, the Kakioma mining facility was digging for zinc ore.
Toxic metals have a variety of harmful effects. Cadmium, arsenic, nickel, chromium, and beryllium can cause cancer, and each of these has additional harmful effects of its own. Lead causes neurological disorders such as seizures, mental retardation, and behavioral disorders, and it also contributes to high blood pressure and heart disease.
Coal and Air Pollution Union of Concerned Scientists
This air pollution includes Mercury Coal plants are responsible for 42 percent of US mercury emissions, a toxic heavy metal that can damage the nervous, digestive, and immune systems, and is a serious threat to the child development.
Boom in Mining Rare Earths Poses Mounting Toxic Risks
The mining of rare earth metals, used in everything from smart phones to wind turbines, has long been dominated by China. But as mining of these key elements spreads to countries like Malaysia and Brazil, scientists warn of the dangers of the toxic and radioactive waste generated by the mines and processing plants.
Mining, manufacturing, and the use of synthetic products (e.g. pesticides, paints, batteries, industrial waste, and land application of industrial or domestic sludge) can result in heavy metal contamination of urban and agricultural soils. Heavy metals also occur naturally, but rarely at toxic
Below is an interesting article submitted on the risks associated to working in the mining industry. On-the-Job Risks of Mining. Coal mining equipment must be monitored on a regular basis to look for faults that can cause sparks and set off explosions. Mercury poisoning symptoms include mouth ulcers, weakness, tremors, bleeding gums
Researchers create lithium-ion batteries with lower levels
According to reports, half the world's supply for cobalt is sourced from Africa, where child labour in the mining industry is still prevalent. The toxicity from cobalt has been shown to cause premature death in these children, by poisoning or susceptibility of children to its toxic effects.

Peru Gold Mining Causes Toxic Mercury Release Pulitzer
It's estimated that gold mining activity annually releases more than 35 tons of toxic mercury into the air and rivers of Madre de Dios, poisoning the food chain. Of course, it's the global demand for gold, with the metal becoming a hedge against financial uncertainty, that's driving illegal mining in Madre de Dios.
