• Evaluation of Developmental Toxicity, Developmental Neurotoxicity, and Tissue Dose in Zebrafish Exposed to GenX and Other PFAS

  Science

  14 Apr 2020 | Environ. Health Perspect.

  Exposure to PFPeS, PFHxS, PFHpS, and PFOS resulted in physical deformities and hyperactivity.

• Evaluation of residues in hen eggs after exposure of laying hens to water containing per‐ and poly‐fluoroalkyl substances

  Science

  13 Apr 2020 | Environ. Tox. & Chem.

  There was a clear correlation between the PFAS concentrations in the drinking water of hens and those detected in the egg, which could be useful in estimating PFAS concentrations in the egg by measuring water concentrations.
