Solve pollution. Save lives. Protect the planet.

Pure Earth has identified mercury as one of the world’s top toxic threats. Because much of the mercury released into the environment is the result of artisanal and small-scale gold mining (ASGM), Pure Earth’s global mercury work focuses on ASGM mining communities around the world.

Understanding The Problem

Mercury is a toxic heavy metal and one of the top ten chemicals of major public health concern, according to the World Health Organization. Pure Earth estimates that 19 million people are at risk for exposure to mercury globally. Exposure to mercury can cause damage to the nervous, digestive, and immune systems, as well as the lungs, kidneys, skin, and eyes. Mercury is particularly dangerous to young children, babies in utero, and pregnant women. The mercury released into the environment knows no borders and contaminates rivers and oceans, fish and other marine animals, and eventually the global food chain. Pure Earth’s Toxic Sites Identification Program has identified and assessed over 500 sites around the world where exposure to mercury threatens the health of the population.

 Toxic Gold:
Mercury and Artisanal Gold Mining

This video explains why and how small-scale gold miners use mercury

The Impact from Artisanal and Small-Scale Gold Mining

Up to 20% of the world’s gold comes from artisanal and small-scale gold mining (ASGM) which is responsible for the release of an estimated 1,000 tons of mercury annually, representing about 30% of the world’s anthropogenic mercury releases, according to United Nations Industrial Development Organization (UNIDO). As much as 95% of all mercury used in ASGM mining is released into the environment. Once released, mercury travels around the world, dropping into oceans and rivers, contaminating the seafood we all consume.

PURE EARTH’S 4-PHASE SOLUTION
to Mercury Pollution Across the Globe

1. FIND MERCURY HOT SPOTS
Work with governments to identify ASGM sites where mercury use is poisoning children and families and damaging ecosystems.

2. MEASURE AND EDUCATE
Assess the extent of mercury contamination in the environment and the level of mercury exposure threatening a community. Educate miners and families on the dangers of mercury use, safe work practices, and methods to protect themselves and their children.

3. TRAIN AND CLEAN UP
Train miners in safe and profitable mercury-free mining techniques; test a range of remediation approaches to remove mercury.

4. REFORESTATION
Replant and restore regions of the Amazon rainforest stripped bare by mining activity. Native tree species are carefully selected for inclusion in landscape restoration. The species offer multiple benefits—ecological, medicinal, economic and more.

Mercury-Free Methods
Mercury-Free Methods
Over 1500 miners trained worldwide

Pure Earth trains miners to go mercury-free, to safeguard their livelihoods and enable them to work safely while protecting their families and environment.

To date, Pure Earth has trained over 1500 miners, including many women, to go mercury-free.

Education 
Education 
Over 6,000 Mining Community Members Reached

Pure Earth raises awareness about mercury poisoning with miners, their families, school children and others in the community.

Our community education and training programs have reached over 6000 mining community members.

Reforestation
Reforestation
About 10 Hectares of the Amazon Rainforest Restored

Pure Earth is one of the few organizations working directly with miners to safely close out old mining sites through reforestation, which rehabilitates previously degraded ecosystems. Miners Pure Earth has worked within Peru calls it “fulfilling their obligation to the rainforest.

To date, Pure Earth has helped artisanal gold miners in Peru restore about 10 hectares of the Amazon rainforest stripped and polluted by gold mining activity.

Connecting Miners with Jewelry Industry

Pure Earth is working to help create awareness and demand for mercury-free gold and connect jewelers and others in this industry to mercury-free miners.
Our efforts include working with the international jewelry industry to find a mine-to-market solution, and supporting women mining cooperatives in Indonesia, and connecting them with local jewelers who agree to buy their mercury-free gold at a premium.

The Toxic Truth

Trapping a Slippery Foe

Pure Earth’s innovative global mercury index explained in The Chemical Engineer magazine.

The Jewelry Industry Can Be A Leader In Solving The Global Issue Of Mercury Pollution From Artisanal & Small-Scale Gold Mining (ASGM)

Why Should the Jewelry Industry Care?

  • Supply chain and reputational risk

> Even best practices cannot ensure that supply chains are completely free of gold from ASGM sources using mercury;

> Without a commitment to mercury-free practices there will always be “dirty” gold that can tarnish the reputation of the industry.

  • Investors, employees and consumers care

> Consumers expect companies to have purpose, societal impact and do no harm;

> Investors are looking for companies that incorporate ESG criteria – profits and purpose are linked;

> Employees want to work for companies that care.

  • It’s the right thing to do

> Being a truly responsible business means going beyond the norm. It means supporting disadvantaged communities and reducing toxic releases. This is true sustainability;

> We have a moral imperative to make the world a better place.
