WHO calls for accelerated action as lead exposure kills over 3.5 million people each year

The World Health Organization estimates that lead exposure is responsible for more than 3.5 million deaths annually, making it a major preventable health threat. Hundreds of millions of children are affected, and even low‑level contact can cause irreversible damage to the brain, heart, kidneys and other organs. In adults, lead contributes to cardiovascular and kidney disease; in children it leads to learning difficulties, behavioural problems and lifelong health deficits. Because symptoms often remain hidden, many cases are identified only after serious harm has occurred.

Lead enters households through a variety of products, including paint, cookware, cosmetics, spices, informal recycling operations and industrial emissions. International Lead Poisoning Prevention Week, held from 18 to 26 October, highlights the preventable nature of the problem. Yet fewer than half of countries have confirmed legally binding controls on lead‑containing paint, leaving large populations exposed to these sources. The diversity of exposure routes underscores the need for comprehensive policies that address both product safety and environmental contamination.

In response, WHO will present a Global Action Plan on Lead Mitigation to the World Health Assembly next year, outlining coordinated strategies for upstream removal of lead from products and environments. The agency also plans to launch the PREVENT Technical Package on Lead Poisoning Prevention in 2027, offering practical guidance on prioritising sources, strengthening regulations and monitoring progress. Building on the Lead Poisoning Prevention Initiative, WHO is expanding laboratory capacity for blood‑lead testing in Brazil, India, Nepal and six sub‑Saharan African nations—Ethiopia, Ghana, Malawi, Rwanda, South Africa and Tanzania—to enable early detection and response.
