  "summary": "Hexafluoropropylene oxide dimer acid (GenX), a replacement for legacy per and polyfluoroalkyl substances (PFAS), is increasingly detected in the environment, yet its chronic toxicity remains poorly characterized. Current safety assessments rely largely on short term, high dose studies that may not capture the biological consequences of long term, low dose exposure. To address this gap, we…",
