Study finds diet and culture influence Hispanic children's exposure to 'forever chemicals'

A recent study led by George Mason University has uncovered that the diet and cultural background of Hispanic children in Northern Virginia impact their exposure to PFAS, chemicals often referred to as "forever chemicals." School meal participation was linked to lower blood concentrations of these pollutants in the children, while higher consumption of animal-based foods was associated with elevated levels of certain PFAS.

The study, published in the Journal of Exposure Science & Environmental Epidemiology, found that English proficiency, being born in the United States, and mothers who had lived in the country longer were all associated with lower exposure to specific PFAS. The research, conducted by Rooshna Mohsin, a recent Ph.D. graduate, and her mentor Professor Michael S. Bloom, is one of the first to examine potential sources of PFAS exposure in children from primarily Central American households.

The study highlights the need for community-informed interventions, such as dietary habits, to mitigate exposure. PFAS, or per- and polyfluoroalkyl substances, are manufactured chemicals used in various products like nonstick cookware and stain-resistant fabrics, but they can also contaminate food and drinking water, persisting in the body for years.

While the study did not examine health impacts, it identifies potential sources of PFAS exposure and opportunities to limit it. The researchers caution that the findings should not be generalized to other communities due to the small sample size and limited scope of the study.
