Pioneering evidence-based solutions to protect children from mercury and lead poisoning

Pure Earth partners with governments, communities and industry leaders to identify and implement solutions that stop toxic exposures, protect health, and restore environments.


USAID Administrator Samantha Power makes groundbreaking statement at the World Economic Forum, calling for global action to end lead poisoning and for funders to join the effort

“I can say right here, that never in my career have I seen an opportunity like the one we are about to discuss – to deliver such a powerful blow to such an invisible killer for such a relatively small amount of funding. And I’m speaking, of course, we are speaking about lead poisoning,” said Power, calling on all funders at Davos to join the effort and substantially increase investment in solutions.



Why Lead + Mercury?

Lead and mercury exposure pose a greater risk than all other Top Ten Chemicals of Concern identified by World Health Organization.


Lead poisoning affects 1 in 3 children, around 800 million globally. This is mass poisoning on a previously unknown scale. 90% of children with high lead levels are in low- and middle-income countries.


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.

Where We Work

With 10 regional offices around the world, Pure Earth has worked on projects in more than 50 low- and middle-income countries. Pure Earth prioritizes locations for long-term investment based on quantitative and qualitative factors.

Understanding Our Impact

Enhancing Health Surveillance
Pure Earth collaborates with governments to enhance health surveillance, revealing the scale and severity of heavy metal exposure. Working in collaboration with implementing partners across six countries, we’ve conducted blood lead level tests for more than 11,500 children and parents.
Identifying Sources of Exposure
Pure Earth conducts investigations to identify the main sources of heavy metal exposure in communities and countries. We've identified nearly 5000 toxic sites across 50+ countries, analyzed 5,800+ consumer product samples for lead contamination in 25 countries, and assessed lead exposure sources in 750+ homes across 6 countries.
Reducing Exposure to Pollution
Pure Earth's impactful interventions result in measurable reductions in exposure to lead and mercury pollution. With over 120 interventions conducted across over 35 countries, we are actively working to diminish the threat of heavy metal poisoning worldwide.
Raising Awareness
Pure Earth uses our research, expertise, and global presence to advocate for ending the multigenerational cycle of mercury and lead poisoning. Between 2020 and 2023, Pure Earth organized 80+ events around the world to raise awareness of the health impacts of pollution, including webinars, briefings, and outreach events.
