Ending the toxic trail of small-scale gold mining UNEP

In a practice that dates back 3,000 years, many small-scale mines add mercury to gold ores to create an amalgam, which is then heated to evaporate the mercury, leaving only gold. Photo Credit: UNEP/Veejay Mercury-dependent artisanal and small-scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The The Mercury Problem in Artisanal and Small-Scale

Health Impact Assessment of Artisanal and Small-Scale Gold Mining

Increasing artisanal and small-scale gold mining (ASGM) in developing countries has raised health concerns in mining communities. A preliminary health survey was conducted in Thabeikkyin Township, Mandalay Region, Myanmar, in February 2020 to assess the health conditions of an ASGM community.The Minamata Convention mandates formalization of artisanal and small-scale gold mining to reduce mercury emissions and releases. In this article, we review the reasons why previous attempts to do this have largely failed, outline miner-centric approaches that are more likely to succeed, and estimate the likely costs of such approaches. We argue Formalizing artisanal and small-scale gold mining: A grand

Emerging mercury mitigation solutions for artisanal small-scale gold

Over 15 million people are involved in artisanal small-scale gold mining (ASGM) globally. Often, ASGM includes smelters that use mercury to extract gold. If mishandled, these actions may cause adverse health effects for smelters and their surrounding communities. There are multiple tools to reduce health risks while involved in gold mining including illegal panning for gold along river beds. However, there is a considerable amount of mining on a small scale for other minerais such as beryl, chromite, vermiculite, agate and clay. Small scale miners are supported by well established government and non-government administrative structures which offerSmall-Scale LYRASIS

The Clinical Importance of the Mercury Problem in Artisanal Small-Scale

Artisanal or small-scale gold mining (ASGM) is usually characterized by the use of rudimentary or basic tools operating at a limited level of production with reduced capital investment. According to the International Labor Organization, ASGM operations are labor intensive, employing low, and basic level mechanization ( 1 ).Areas identified as gold mining in the land cover classification model were further differentiated into two categories: large-scale, industrial mining and small-scale, artisanal mining. Industrial mining operations within the study period (2005–2019) were assumed to have a significant change in elevation because of the nature of the mining The large footprint of small-scale artisanal gold mining in Ghana
