Mercury Poisoning in Artisanal Gold Mining: A Growing Threat to Tropical Forested Ecosystems

Artisanal and small-scale gold mining (ASGM) has become a significant threat to tropical forested ecosystems around the world. While ASGM provides an important livelihood for local communities, it also results in widespread deforestation, environmental degradation, and exposure to mercury poisoning. In this article, we will explore the impact of ASGM on the environment and human health, particularly with regards to mercury emissions.

The use of mercury in ASGM is staggering. It is estimated that 675-1000 tons of mercury are volatilized and emitted to the atmosphere globally from ASGM operations each year. This has shifted the major emission source of atmospheric mercury from the Global North to the Global South, with significant consequences for patterns in mercury fate, transport, and exposure.

ASGM sites are often located within global biodiversity hotspots, leading to decreased diversity, loss of sensitive species, and high exposure to mercury in both people and top predators. The use of mercury in ASGM is not only harmful to the environment but also poses a significant threat to human health. Mercury exposure has been linked to neurological damage, birth defects, and other serious health problems.

Despite its negative impacts, ASGM remains an important livelihood for many local communities. However, it is essential that governments and international organizations work together to mitigate the environmental and health impacts of ASGM. This can be achieved through the implementation of sustainable mining practices, regulation of mercury use, and provision of alternative livelihoods for affected communities.

In conclusion, mercury poisoning in artisanal gold mining is a growing threat to tropical forested ecosystems around the world. It is essential that we take action to mitigate its impacts and promote more sustainable mining practices. By working together, we can reduce the harm caused by ASGM and protect the health of our planet and its inhabitants.
