On 22 October, during International Lead Poisoning Prevention Week, the World Health Organization (WHO) stated that countries need to accelerate their efforts to prevent exposure to lead.

Lead exposure is estimated to cause more than 3.5 million deaths every year around the world.

Children are at particularly high risk because their developing brains and nervous systems are more vulnerable to the toxic effects of lead. It is estimated that as many as 815 million children are affected by lead, a figure equivalent to one in three children worldwide. Young children are especially vulnerable because they absorb more ingested lead than adults and frequently put their hands and objects into their mouths.

Lead contamination can occur through cooking utensils, cosmetics, spices, informal recycling, and industrial sources. There is no known safe level of exposure, and even relatively low levels can cause irreversible harm. In addition, exposure risks vary depending on local economic activities, environmental conditions, and living situations.

Although lead exposure is preventable, WHO’s latest global assessment shows that fewer than half of countries have established legally binding regulations on lead-containing paint.

In May 2026, WHO released an overview module of its “PREVENT technical package for lead poisoning prevention.” The aim of this framework is to help countries turn evidence into action by prioritizing pollution sources, monitoring exposure, and responding to elevated blood lead levels. The full package is scheduled for release in 2027 and will provide countries with practical guidance.

In 2025, WHO also worked with partners in the “Lead Poisoning Prevention Initiative” to build and strengthen the capacity of laboratories to test blood lead levels, enabling early detection of lead exposure. Capacity-building and technical support are planned for Brazil, India, Nepal, and six countries in sub-Saharan Africa.

The 2026 campaign, “From Detection to Prevention,” focuses on the fact that lead poisoning is often invisible and has many causes, making it essential first to identify where it exists. By coordinating across a wide range of fields—including health, environment, education, industry, and labor—it is possible to protect people’s health.
