How do everyday plastics and ‘forever chemicals’ shape a child’s earliest months of life? A new University of Hawaiʻi at 惭ā苍辞补 study is set to find out by following 300 local families.
Funded by the National Institute of Environmental Health Sciences, part of the National Institutes of Health, the Hawaiʻi-based study tracks families from the first trimester through the baby’s first year.
PFAS (Per- and polyfluoroalkyl substances), often called “forever chemicals,” are widely used in consumer products. Microplastics are plastic particles smaller than 5 millimeters. Both can enter the body through food, water, air and everyday products and have been detected in human tissues.
The five-year study is co-led by Shiwen “Sherlock” Li, assistant professor and Chin Sik and Hyun Sook Chung Endowed Chair in the Thompson School of Social Work & Public Health’s , and Cassandra L. Hendrix, assistant professor in the .
“Pregnancy and infancy are critical windows of development, when the brain and other parts of the body are rapidly forming and may be especially vulnerable to environmental exposures,” said Li. “By studying PFAS and microplastics during this early period of life, we hope to understand whether these exposures can influence a child’s brain development and generate knowledge that can help give every child a healthier start in life.”
Hawaiʻi-focused study
Hawaiʻi provides an important setting for the research because ocean currents concentrate microplastics on island shores and in marine life, while previous research estimated Hawaiʻi’s per-capita seafood consumption at about 1.8 times the U.S. average.
Researchers will measure exposure through maternal blood, examine fetal brain development through ultrasound and collect cord blood and placenta samples. Infants will be assessed at 2, 6 and 12 months for neurological function, motor development, language skills and cognition.
“By doing assessments early and often, we can see when these chemicals first impact babies’ brain development,” said Hendrix. “Knowing when and how babies are affected can inform policies and interventions that will support families across the Hawaiian Islands.”
