Meta-Analysis of Public Perception on Per- and Polyfluoroalkyl Substances (PFAS)

Abstract

Poly- and perfluoroalkyl substances (PFAS) are a class of synthetic chemicals widely used in consumer products due to their durability and resistance to water and oil. However, their environmental persistence and potential health hazards, such as immune suppression, liver damage, and increased cholesterol, have raised significant public health concerns. Despite these risks, public awareness of PFAS remains limited, with varied levels of concern across demographic groups. This meta-analysis synthesizes findings from nine studies published between 2018 and 2024 to evaluate trends in public perception of PFAS. Results show a notable increase in publications on PFAS awareness, reflecting a growing recognition of their risks. Analysis of demographic factors reveals that higher educational attainment is generally associated with increased PFAS concern, though the effect varies across education levels. Additionally, racial differences suggest that certain groups, such as Black or African populations, exhibit higher PFAS concern, whereas White and Other groups show lower levels of concern. These findings highlight the importance of targeted public health outreach to enhance PFAS awareness and address demographic disparities. By identifying patterns in public perception, this study provides insights for developing effective communication strategies and policy interventions aimed at reducing PFAS exposure risks.
