Removing lead from the global economy

Area of Science:

• Environmental Science
• Toxicology
• Global Health

Background:

• Lead is a naturally occurring element sequestered in the lithosphere.
• Human activities extract and distribute lead, leading to widespread toxic effects.
• Lead pollution impacts biological processes across all life forms.

Purpose of the Study:

• To highlight the extensive harms caused by lead mining and manufacturing.
• To quantify the global economic and health costs of lead exposure.
• To advocate for the elimination of lead from the global economy.

Main Methods:

• Review of lead's toxicological impacts on various organisms.
• Analysis of economic costs associated with lead exposure, including cardiovascular disease and impaired cognitive development.
• Assessment of lead recycling practices and environmental dispersal, particularly in low- and middle-income countries.

Main Results:

• Lead exposure causes 5.5 million premature adult deaths from cardiovascular disease annually.
• Global economy losses reach US$1.4 trillion due to lead's impact on children's cognitive development.
• Millions of metric tonnes of lead are dispersed annually, with disproportionate impacts on lower-income nations.

Conclusions:

• Lead's pervasive toxicity necessitates urgent global action.
• Available substitutes for lead exist, making its elimination feasible.
• Eliminating lead from the global economy by 2035 is essential for planetary and human well-being.
