Artisanal and small-scale mining (ASM) is a vital livelihood practice around the world, especially in Global South. In Tanzania, millions of people depend on artisanal gold many these are Geita, main region Tanzania. Based qualitative research conducted this region, paper engages miners’ experiences mining. It highlights how extracting experienced as increasingly difficult miners worry that res...
BACKGROUND In 2010, Médecins Sans Frontières discovered a lead poisoning outbreak linked to artisanal gold processing in northwestern Nigeria. The outbreak has killed approximately 400 young children and affected thousands more. OBJECTIVES Our aim was to undertake an interdisciplinary geological- and health-science assessment to clarify lead sources and exposure pathways, identify additional ...
Innovation is an important source of economic growth and competitive advantage. Consequently, a diverse literature in economics and management addresses a variety of questions about how to manage technological change. This paper explores the "opposite" question: What explains the absence of change? We apply existing theories of non-adoption to our case study, salt mining in the Sahara desert, i...
BACKGROUND The continuous exposure to inorganic mercury vapour in artisanal small-scale gold mining (ASGM) areas leads to chronic health problems. It is therefore essential to have a quick, but reliable risk assessing tool to diagnose chronic inorganic mercury intoxication. This study re-evaluates the state-of-the-art toolkit to diagnose chronic inorganic mercury intoxication by analysing data ...
For the last two decades, Congolese Artisanal and small-scale mining (ASM) sector has been undergoing reforms of its governing structures. A recurrent argument supporting — predominantly in 3T ASM (i.e. tin, tantalum tungsten) is that artisanal feeds violence (including sexual violence), conflicts, underdevelopment, poverty.

Artisanal gold mining caused widespread contamination resulting in the deaths of > 400 children. Socioeconomic, logistic, and security challenges required remediation and medical protocols within the context of local resources, l...
Artisanal and Small-Scale Gold Mining (ASGM) is mining of gold deposits with simple physical chemical characteristics using equipment technology. In 2005, total mercury release in the environment ASGM was more than twice from this sector, around 35% mercury, an annual estimate at 727 tons, becoming largest global resource anthropogenic release. Indonesia, released to estimated 340 metric tons p...
