Lead exposure is tied to 3.5 million deaths a year
WHO attributes more than 3.5 million deaths in 2023 to lead exposure and says up to 815 million children are affected. Pure Earth puts the number above one billion.
How this affects people
Lead damages brain development and learning in children and drives cardiovascular disease in adults. WHO counts more than 71.5 million healthy life years lost to it in 2023.
Sources include informal recycling of lead-acid batteries, lead in cosmetics, cookware and spices, pigments and paints, mining and smelting, and contaminated water from pipes. Estimates of affected children differ by source: WHO says up to 815 million, Pure Earth says more than one billion.

What could happen next
The future leaves room for choices. Compare the outlooks, check what supports them and notice where the evidence becomes less certain
A large, mostly cardiovascular burden
WHO attributes more than 3.5 million deaths in 2023 to lead exposure, primarily through cardiovascular effects.
The future is not a timetable. These summaries reflect published scenarios and trends, with deeper uncertainty at longer horizons. Choices made now matter.
