What is the purpose of this study?

Researchers at the Pacific Northwest Center for Translational Environmental Health Research Oregon State University are working with Klamath County Public Health to learn more about pregnant individuals' personal exposure to chemicals and particles in the air before and during the wildfire season in Klamath County. The data collected by Oregon State University will help us understand what is in wildfire smoke and how this might impact health during pregnancy and after birth.

This project was initiated by Klamath County Public Health (KCPH) in response to concerns about ongoing and unexplained high rates of infant mortality, preterm birth, and low birthweight, alongside years of heavy wildfire smoke impact.

Principal Investigator: Diana Rohlman, PhD
