TL;DR:
Endocrine-disrupting chemicals (EDCs) can interfere with hormones and are linked to disease across populations. Research estimates that EDC exposure costs the U.S. hundreds of billions of dollars each year—more than in Europe—likely due to differences in chemical exposure and regulation. Reducing exposure may lower long-term health risks and healthcare costs.
Pollution is Driving Up Our Health Costs
Research published in The Lancet examined how endocrine-disrupting chemicals (EDCs) contribute to disease and healthcare costs. EDCs are chemicals that can interfere with hormone systems and affect development, metabolism, and brain function.
Because chemical regulations differ between Europe and the United States, researchers used these differences to estimate disease burden and economic impact.
They found that EDC exposure accounts for more than 2% of the U.S. gross domestic product, or about $340 billion per year. In Europe, the estimated cost was lower — about $217 billion, or 1.3% of GDP. The authors concluded that differences in chemical exposure and regulation likely explain much of this gap.
In the United States, flame retardants called polybrominated diphenyl ethers (PBDEs) were a major contributor. PBDE exposure was linked to significant loss of IQ points and higher rates of intellectual disability, accounting for most of the estimated U.S. costs. These chemicals have been widely used in furniture, electronics, vehicles, and building materials.
In Europe, the largest contributors to cost were organophosphate pesticides, which were linked to neurological and developmental effects. Pesticide-related costs were much lower in the United States, reflecting differences in use patterns and regulation.
The authors concluded that improved screening for endocrine-disrupting chemicals and preventive regulation could significantly reduce disease burden and healthcare costs, particularly in countries with higher exposure levels.
