Artisanal and small-scale gold mining and biodiversity: a global literature review

Ecotoxicology
Artisanal and small-scale gold mining (ASGM) is crucial to the livelihoods of close to 20 million people in over 80 countries, including 4-5 million women, mainly in rural areas with limited alternative economic prospects, particularly in developing countries.

Environmental Impact of Small-scale and Artisanal Gold Mining in Southern Ecuador

AMBIO: A Journal of the Human Environment, 2000
Small-scale gold mining in southern Ecuador is causing considerable environmental impacts, the most important of which are related to the discharge of metals, metalloids and cyanide into adjacent rivers. In the rivers, these contaminants are generally not present in water-soluble forms, but are instead associated with suspended particles and river bed ...

Tracing Atmospheric Mercury from Artisanal and Small-Scale Gold Mining

Environmental Science & Technology
Artisanal and small-scale gold mining (ASGM) is one of the largest primary sources of mercury (Hg) pollution in the atmosphere globally; however, there is a paucity of atmospheric Hg data in ASGM areas. We measured atmospheric gaseous elemental mercury (GEM) concentrations and stable Hg isotopes at fine spatial resolution in the Madre de Dios region of

Responsible gold sourcing from artisanal and small-scale mining

2016
Public and political discussions increasingly acknowledge the role of responsible supply chains in order to support decent working conditions, protect the environment and apply adequate due diligence. In recent years, companies have demonstrated that through applying supply chain due diligence they may act as partners contributing to improved ...

A behavioral model of collective action in artisanal and small-scale gold mining

Ecological Economics, 2015
There is a rising global concern about mercury use in small-scale gold mining because of its harmful effects on ecosystems and human health. Associative entrepreneurship has been promoted as a way of accessing alternative techniques to address this concern.

Characterization and Reprocessing of Artisanal and Small-Scale Gold Mine Tailings

Mining, Metallurgy & Exploration
Millions of tons of solid waste are generated by artisanal and small-scale gold mining in several regions of the world. This study focused on the tailings from the Abu Hamad artisanal gold mine located in northeastern Sudan. The results of the analyses carried out showed that this amalgam waste contained on average 5.5 g/ton of gold, 50 g/ton of ...

Environmental and health risk of artisanal and small-scale gold mining in Ghana: a review

Environmental Science and Pollution Research
Artisanal and small-scale mining (ASM) has emerged as a vital economic lifeline for millions across Africa, Asia, and Latin America, driven by increasing gold prices, global demand, unemployment, and poverty. This sector accounts for approximately 28.9% of Ghana's GDP and provides a livelihood for nearly 70% of Ghanaians, predominantly those residing ...

Degradation of mine site alluvial soil – the case of artisanal and small-scale gold mining in Ghana

Environmental Monitoring and Assessment
Artisanal and small-scale mining (ASM) is contributing to land degradation and loss of fertility of agricultural soils in Ghana. Although there is a legal requirement for soil restoration after mining, it is rarely carried out, and when it is done, it is often inconsistent with regulatory requirements.

Risk management framework for methylmercury in artisanal small-scale gold mining

2023
Artisanal Small Scale Gold Mining (ASGM) is largely a poverty-driven activity that has become the largest contributor (i.e., 38%) to mercury pollution globally. There is growing evidence that the sector is expanding rapidly with an increased emission of mercury into the environment.
