What are the environmental impacts of gold mining?
Gold mining is one of the most destructive industries in the world. It can displace communities, contaminate drinking water, hurt workers, and destroy pristine environments. It pollutes water and land with mercury and cyanide, endangering the health of people and ecosystems.
What are the dangers of mining gold?
Artisanal and small-scale gold mining is a vital source of income, but it is also very dangerous because miners use toxic mercury to separate the gold from the ore. Mercury is a shiny liquid metal that attacks the nervous system. Exposure can result in life-long disability, and is particularly harmful to children.
What are positive impacts of mining?
In terms of positive impacts, mining is often a source of local employment and may contribute to local and regional economies [18, 19]. Remediation of the potential environmental impacts, for example through water treatment and ecological restoration, can have positive net effects on environmental systems .
Why is gold mining bad?
Artisanal gold mining releases mercury into the environment in its metallic form during amalgamation and as mercury vapor during the burning process. Once mercury is released into waterways, it enters the food chain through the digestion of bacteria and becomes the far more toxic – methylmercury.
