Lead Exposure Action Fund
One in Three Children Is Being Poisoned
Lead is a preventable neurotoxin quietly stealing IQ, health, and lives from hundreds of millions of children in poorer countries.

The evidence
A Third of the World's Children
An estimated 815 million children globally, roughly one in three, have blood lead levels at or above the threshold that requires action (UNICEF/Pure Earth, The Toxic Truth, 2020). Nearly half of them live in South Asia.
A Silent Mass-Casualty Event
Lead exposure is now estimated to cause approximately 1.5 million deaths a year worldwide, mostly from cardiovascular disease it triggers in adults (WHO/IHME, 2021), plus more than 33 million years of healthy life lost to disability.
Stealing IQ Before Birth
In 2019 alone, lead exposure cost the world's children an estimated 765 million IQ points, with roughly 95 percent of that loss falling on kids in low- and middle-income countries (The Lancet Planetary Health, 2023). This damage is permanent.
A Trillion-Dollar Drain
Childhood lead exposure costs low- and middle-income countries close to $1 trillion a year in lost economic potential (UNICEF, Pure Earth, World Bank, The Toxic Truth, 2020), exceeding 10 percent of GDP in these countries.
The Spice in the Cabinet
Turmeric processors across South Asia have long brightened their product with lead chromate, an industrial pigment otherwise used in paint (Stanford University/icddr,b). In Bangladesh, 47 percent of market turmeric samples tested positive before a coordinated crackdown brought contamination to zero.
Batteries, Paint, and Cookware
Up to half of all used lead-acid batteries worldwide are stripped down in informal, unregulated recycling operations. Lead paint remains legally unrestricted in more than half of all countries, including roughly 90 percent of low-income nations (UNEP, 2021).
What we can do
Groups like the Lead Exposure Elimination Project report preventing a case of childhood lead exposure for about $1.66. Phase 1 is detection and enforcement, cheap field testing of spices, paint, and consumer goods paired with real penalties. Phase 2 is regulation, universal legally binding lead paint limits and formalized, safe battery recycling. Phase 3 is remediation, testing and treating contaminated hotspots before more IQ points, and lives, are lost.
