COVID-19 isn't the only problem going viral. Economic insecurity is driving gold prices to record highs around $1,700 per ounce, causing levels of global mercury pollution to rise too.In the United States coal-fired power plants drive mercury pollution, but globally, the leading cause is small-scale 'artisanal' gold mining. Roughly 30 million men, women, and children in poor countries ...

Abstract. Artisanal and small-scale mining (A&SM) is a growing economic sector in many third-world countries. This review focuses on anthropo-geomorphic factors and processes associated with small-scale opencast mining (SSOM), a form of A&SM in which near-surface ores are extracted by removing relatively thin covers of soil, bedrock or sediments.
