• Toxic PFAS, the “everywhere chemicals,” are in organic pasta sauce and ketchup, drugs, pesticides, and foodware

  News

  8 Jun 2022 | Sierra

  Organic pasta sauce and ketchup, common medicines and drugs such as Flonase nasal spray, Prozac, and Cipro, and even the basic packaging in which our foods are wrapped were found to be contaminated with a toxic class of chemicals known as PFAS.

• State rolls out dashboard showing PFAS monitoring results for drinking water

  Policy

  7 Jun 2022

  Minnesota residents who get their drinking water from a community public water system will now be able to find out if their system’s water has any level of PFAS, through an interactive online dashboard unveiled today by the Minnesota Department of Health.

• EPA Issues First Test Order Under National Testing Strategy for PFAS in Commercial Fire Fighting Foam and Other Uses

  Policy

  6 Jun 2022

  "For far too long, families across America, especially those in underserved communities, have suffered from PFAS. High-quality, robust data on PFAS helps EPA to better understand and ultimately reduce the potential risks caused by these chemicals,” said EPA Administrator Michael S. Regan.

• Colorado bans PFAS in oil- and gas-extraction products

  News

  6 Jun 2022 | C&EN

• Concerning measures to increase protections from perfluoroalkyl and polyfluoroalkyl chemicals

  Policy

  6 Jun 2022

  The Colorado state legislature passed HB22-1345, which was signed into law by Gov. Jared Polis (D).

• Is the use of paper food contact materials treated with per- and polyfluorinated alkyl substances safe for high-temperature applications? – Migration study in real food and food simulants

  Science

  6 Jun 2022 | Food Chemistry

  Several PFAS migrated from paper-based food contact materials into real food, contributing significantly to tolerable weekly intake.

• Early-pregnancy plasma per- and polyfluoroalkyl substance (PFAS) concentrations and hypertensive disorders of pregnancy in the Project Viva cohort

  Science

  6 Jun 2022 | Environ Int

  Exposure to certain PFAS may increase the odds of gestational hypertension during pregnancy, with potential implications for maternal and child health outcomes.

• Per- and polyfluoroalkyl substances (PFAS) exposure in women seeking in vitro fertilization-embryo transfer treatment (IVF-ET) in China: Blood-follicular transfer and associations with IVF-ET outcomes

  Science

  6 Jun 2022 | Sci Total Environ

  Based on their physicochemical properties, many PFAS can easily cross the blood-follicle barrier, but there was no significant association between PFAS concentrations and select in vitro fertilization outcomes.
