  F-53B was found to be removed most efficiently with surface modified nanoclay from electroplating wastewater.

• The Biden plan to secure environmental justice

  Policy

  10 Nov 2020

  Biden will tackle PFAS pollution by designating PFAS as a hazardous substance, setting enforceable limits for PFAS in the Safe Drinking Water Act, prioritizing substitutes through procurement, and accelerating toxicity studies and research on PFAS.

• Associations between six common per- and polyfluoroalkyl substances and estrogens in neonates of China.

  Science

  10 Nov 2020 | J Hazard Mater

  A review of the current methods to both detects the presence of fluorine and specific PFAS to better help regulators identify public health or environmental hazards.

• Emerging per- and polyfluoroalkyl substances (PFAS) in human milk from Sweden and China

  Science

  22 Sep 2020 | Environ Sci Process Impacts

  The significant concentrations of F53-B in Chinese milk suggest that human exposure assessments focused only on legacy substances may severely underestimate overall PFAS exposure in breastfeeding infants.
