Harvard T.H. Chan School of Public HealthSep 9 2024 Higher exposure to fine particulate air pollution during infancy was associated with lower economic earnings in adulthood in a new study from Harvard T.H. Chan School of Public Health, Harvard John A. Paulson School of Engineering and Applied Sciences, and European University of Rome. The association was most pronounced in the midwestern and southern U.S.
"This study takes a big step toward filling the knowledge gap on the crucial link between environmental factors and long-term economic outcomes," said corresponding author Francesca Dominici, Clarence James Gamble Professor of Biostatistics, Population, and Data Science at Harvard Chan School and faculty director of the Harvard Data Science Initiative.
The study found that the higher a person's exposure in infancy to PM2.5, the lower their earnings in adulthood. Nationwide, on average, an increase in PM2.5 exposure by one microgram per cubic meter in 1982 was associated with a 1.146% lower AUM in 2015. The study also found that PM2.5 exposure had an outsize impact on AUM in specific regions of the U.S., particularly in the Midwest and South.

"They also suggest the necessity of locally tailored interventions to mitigate air pollution and of integrated policies that address both environmental and economic inequalities."
