Abstract

A recent World Bank Report ‘A World Without Lead: Paving the Path to a Healthy Productive Future’ describes the global lead poisoning crisis, and its impacts on health, the environment, and human capital. The report offers a roadmap for eliminating exposure, comprising strategic investments, policy reforms and foundational public health practices like monitoring and surveillance that every country can use to address this crisis.

Removal of lead from gasoline reduced average blood lead levels globally but was not the only source of lead. Global lead consumption exceeded 12 million tons in 2022. Toxic emissions are routinely released from formal and informal lead mining, smelting and recycling and contaminate adjacent communities.  Lead is found in a multitude of foodstuffs, remedies, low fire glazed pottery, jewelry, leaded residential paint and water pipes. One study estimated that 800 million children worldwide, most living in low-middle income countries, have blood lead levels known to affect learning, behavior and later adult health.

But good news: fugitive emissions from lead mining and smelting can be controlled, contaminated sites can be cleaned up, and old lead mines can be permanently closed. Lead contamination of foodstuffs and leaded paint have been successfully regulated. Population-level blood lead surveillance, together with studies of blood and environmental lead levels in areas with known lead contamination, help countries and communities identify risks and monitor progress to eliminate the danger. And, the costs of these interventions are far less than the costs of letting the exposure continue. 

In this seminar, Dr. Brown will describe the current status of lead exposure with a focus on low and middle income countries, the expected costs/benefits of eliminating exposure globally, and the work that remains to be done.
