ARTISANAL AND SMALL-SCALE GOLD MINING AND HEALTH 2 1.1 SCOPE AND PURPOSE An early version of this report served as a background document for a WHO technical consultation on artisanal and small-scale gold mining and health, which took place on 1-2 October 2014 in Geneva, Switzerland. The overarching goals of this meeting were to:
[email protected]Jun 15, 2021 Gold mining is the largest source of mercury (Hg) pollution worldwide. The discharge of mercury in the environment bears direct human health risks and is likely to increase cascading effects throughout local food chains. In the Peruvian Amazon the mining process consists of slashing and burning trees, followed by extraction of gold-bearing
Get PriceDec 01, 2020 Mining is very vital to the production of goods, services and infrastructure; it advances the quality of lives in the society. However, the possible hazard of waste and radioactivity generated by mining, dumping and tailing, has called on the society to find ways of seeking remedy that will adequately treat mining waste from mine dump, tailing and abandoned mine
