This is what illegal gold mining does to the Amazon in Brazil — once lush jungles filled with all manners of tropical life are reduced to a hellscape of desert, mercury-polluted ponds, poisoned species and dislocated people. I’ve seen this damage up close in Madre de Dios, Peru. It is heartbreaking — and unrelenting.

They are clogging and redirecting streams with dams and waste materials or “tailings”. And worst of all, they are poisoning water-sources with the neuro-toxin mercury, endangering not only their own lives but the lives of all those who live nearby.
To effectively communicate with mining communities about mercury, it is crucial to consider culturally appropriate strategies, community social networks, and the socio-technical nature of the issue.

The project also supports gold miners and other players in the artisanal gold value chain to adopt good practices. Examples include eliminating the use of toxic products such as mercury from mining sites, ensuring the revenues from the gold do not help fund armed groups, reducing the environmental impact and, finally, initiating reforms at national level to improve governance.

The Executive Director of the Water Resource Commission (WRC), Dr Bob Alfa, has warned about the growing danger posed by illegal mining, known locally as galamsey, to water security and the ultimate threat to peace in Ghana and with neighboring countries.
These activities involve the unregulated extraction of gold and other minerals, often using environmentally destructive methods such as mercury amalgamation and indiscriminate excavation. Galamsey pollutes water sources with toxic chemicals, sedimentation, and siltation, degrading water quality and disrupting aquatic ecosystems.

Background Artisanal and small-scale gold mining (ASGM) areas potentially pose increased exposure to arsenic and mercury through community contamination, occupations at gold mines, and/or geophagy when soil is locally sourced.
The Tapajós River basin in Brazil is one of the world's regions most affected by artisanal gold mining (ASGM), which is responsible for the release of mercury and high energy consumption. Mercury, mixed with gold-containing materials and then released through heating to extract the gold, can be recovered using a simple distillation device called a retort

Indigenous people say armed miners threaten them, scare off wild game, and pollute rivers with mercury – poisoning the fish and their drinking water.
Mercury (Hg) is a heavy metal that can cause several adverse health effects based on its form (organic, inorganic or elemental), duration and pathway of exposure. Measurement of mercury present in human biological media is often used to assess human exposure to mercury at mining sites.

The “artisanal” label added to small-scale miners refers to their labor-intensive methods for extracting minerals. The work is associated with unsafe working conditions; the illegal use of mercury and cyanide, unrehabilitated pits, and environmental damage. Miners can fall sick, communities can lose drinking water, and the precious metals they unearth can contribute to and fund conflicts and corruption.

Artisanal and small-scale gold mining uses mercury to isolate gold from ore. Although uncommon in the United States, it is more common in poor and undeveloped countries. This practice requires heating mercury, which vaporizes into an odorless gas that can be inspired and absorbed into the blood.

The group’s pioneering work in artisanal small-scale gold mining to reduce the use of mercury among women and men miners has been consistent with this thrust. The current campaign to reduce the prolific use of mercury-added skin-lightening products is another important advocacy that exemplifies how gender mainstreaming takes into account the differences in the situation of women and men,” Edel Garingan from BAN Toxics said in the webinar.
Illegal gold mining has also led to contamination of the rivers with mercury, a substance highly toxic to humans, especially children. A report by the Carnegie Amazon Mercury Project states that the mercury level of children in native communities is more than five times higher than the safety limit.

Additionally, water resources, which serve as sources of potable water for drinking and irrigation, are heavily contaminated with arsenic, mercury, lead, copper, and nickel. The study concluded that implementing stricter regulations on mining practices, promoting sustainable mining methodologies, and providing comprehensive training to miners on environmental protection and land rehabilitation can help mitigate the negative impacts of ASM.

“These miners are the number one source of mercury pollution on the planet, and they don’t do it because they don’t care about the environment,” said Dr. Adam Kiefer, Distinguished University Professor of Chemistry at Mercer. “They do it because they need to feed their families.

This study presents a picture of ASGM in Brazil and prospective numbers on mercury emissions and releases in 2016, when the country declared production of about 90 tonnes of gold, of which circa 25 tonnes came from ASGM. However, it is also necessary to consider the illegal production of ASGM which is estimated to vary between 10% and eight times more than the legal production.
Artisanal small-scale gold mining (ASGM) is the world's largest anthropogenic source of mercury emission. Gold miners are highly exposed to metallic mercury and suffer occupational mercury intoxication. The global disease burden as a result of this exposure is largely unknown because the informal character of ASGM restricts the availability of reliable data.

The gold mining sector, particularly in the Amazon region, exemplifies the environmental challenges associated with mining, including mercury pollution and deforestation. The reform of the mining code is seen as a crucial step towards mitigating these impacts and ensuring the sustainability of the industry. By attracting new investments and diversifying the sources of equipment and services, Brazil aims to foster a more responsible and competitive mining sector.

Despite being a vital economic driver for 20–30 million people, ASGM threatens the health of aquatic systems from Hg pollution, presenting a complex challenge that demands urgent interventions.

.Bolivia has long been criticised for using mercury in small-scale gold mining, and growing evidence shows that mercury contamination is causing illnesses in poor communities. Mercury is used across the country, in mining projects in the cordilleras of the Andes and on dredgers extracting gold from the sediment at the bottom of waterways. The uncontrolled disposal of mercury waste creates toxic flows in Bolivia’s river systems.
Artisanal gold mining uses metallic mercury to form an amalgam with gold containing ore. Heating of this amalgam causes the mercury to evaporate and leave behind the gold contained in the ore
