Summary Artisanal and small-scale gold mining (ASGM) is the world's largest source of anthropogenic mercury emissions releases. These have devastating consequences for miners' health environment. Most >20 million ASGM miners worldwide are not officially recognized, registered, regulated, or protected by state laws. Formalization—the process organizing, registering, reforming ASGM—is ma...
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...
• Mercury exposure (blood, urine and hair) in 238 ASGM miners was assessed Colombia. A 55% of the (n = 131) had Hg/methylmercury values hair above EPA threshold. levels amalgam burners were 6 to 8-fold higher than all other miners. Fish intake, burning manipulate significant indicators Hg exposure. Exposure clearly depend on different processing activities carried out ASGM. With aim protecting ...
Since its advent at the end of nineteenth century, cyanide processing facilitated intensification and global expansion industrial gold mining. Today, there are important indications that artisanal small-scale mining (ASGM) is on verge a similar revolution: while ASGM typically associated with mercury-based processing, mercury amalgamation increasingly replaced with, or complemented by, cyanidat...
This article argues that adopting a gender perspective when regulating artisanal and small-scale mining (ASM) is both necessary achievable. The authors analyse women’s often-ignored needs experiences as workers, decision-makers affected community members in the ASM sector. To address these concerns, this sets out standards for to guarantee access services information decision-making representat...
Artisanal and small-scale mining (ASM) is an important livelihood activity in many low- middle-income countries. It widely acknowledged that there are a myriad of health risk opportunities associated with ASM. However, little known regard to which aspects have been studied ASM settings. We conducted scoping review peer-reviewed publications, using readily available electronic databases (i.e., P...
