Airborne PCBs and how they may affect teen brain development
Airborne PCBs and Their Metabolites: Risk Factors for Adverse Neurodevelopmental Outcomes in Adolescence
This project looks at whether breathing airborne PCBs and the chemicals they form in the body harms brain development in adolescents.

What this research studies
You will learn about research focused on PCBs found in school and Superfund-site air and whether breathing them affects teen brain development. Researchers study how parent PCBs and their metabolites impact astrocytes, the brain support cells, by causing oxidative stress and mitochondrial dysfunction. The team combines measurements of PCB mixtures in school air, lab studies using human-relevant cells or samples, and analyses related to adolescent neurodevelopment to connect exposure to functional outcomes. The goal is to explain mechanisms that could link inhaled PCBs to changes in learning, behavior, or brain function during adolescence.
Who could benefit from this research
Good fit: Adolescents roughly 12–20 years old who attend schools or live near PCB-contaminated sites or who are concerned about airborne PCB exposure would be the most relevant candidates.
Not a fit: People whose neurological problems are clearly unrelated to adolescent PCB exposure or whose exposure occurred long before adolescence may not receive direct benefit from this work.
Why it matters
Potential benefit: If successful, this work could point to ways to reduce harmful air exposures in schools and guide interventions to protect adolescent brain health.
How similar studies have performed: Previous studies have linked PCBs to neurodevelopmental problems and implicated astrocytes, but directly tying school-air PCB mixtures and human metabolites to adolescent outcomes is a newer area of work.
