TL;DR: Key points with love ❤️

A group of 20 internationally renowned scientists has issued a strong warning against attempts to narrow the definition of 'forever chemicals' (Per- and polyfluoroalkyl substances - Pfas). They argue this effort, potentially influenced by some within the International Union of Pure and Applied Chemistry (IUpac), is politically or economically motivated to weaken regulation. Such a change could drastically reduce the scope of control, undermine monitoring, and weaken public health and environmental protections in regions like the EU and UK.

Trending
  1. 1 Last year: IUpac launched a project aimed at providing a rigorous definition of Pfas.
  2. 2 This week: A group of 20 scientists published a paper in Environmental Science & Technology Letters defending the current definition.
  3. 3 Ongoing: Regulation regimes for Pfas are being worked out in the EU and UK.
  • Potential weakening of Pfas regulation
  • Reduced scope of substances subject to control
  • Undermining of monitoring efforts
  • Potential weakening of public health and environmental protections
  • Substantial delays in scrutiny and regulation of harmful contaminants
What: International scientists are warning against efforts to narrow the definition of 'forever chemicals' (Pfas).
When: A paper was published this week in Environmental Science & Technology Letters; IUpac launched a project last year.
Where: International context, with implications for regulation in the EU and UK.
Why: Scientists believe the attempts to change the definition are politically and/or economically motivated, aiming to weaken regulation and reduce the number of substances subject to control, thereby undermining public health and environmental protections.
How: By publishing a paper defending the current OECD definition and urging policymakers to continue using it, while also highlighting the potential negative impacts of a narrower definition.
