SUMMARY

The discussion centers on the detection and elimination of per- and polyfluoroalkyl substances (PFAS), particularly focusing on the status of PFAS in the United States and internationally. PFAS, including PFOA and PFOS, are persistent chemicals linked to adverse health effects and have been phased out in U.S. manufacturing due to initiatives like the PFOA Stewardship Program. However, these substances continue to be produced globally and can still enter the U.S. market through various consumer goods. The Environmental Protection Agency (EPA) clarifies that while some PFAS are no longer manufactured domestically, imports remain a concern.

PREREQUISITES
  • Understanding of PFAS chemistry and its environmental impact
  • Familiarity with detection instruments for PFAS, such as mass spectrometry
  • Knowledge of regulatory frameworks regarding PFAS, including the PFOA Stewardship Program
  • Awareness of international regulations on PFAS, particularly in the EU
NEXT STEPS
  • Research the latest detection methods for PFAS, focusing on mass spectrometry techniques
  • Explore the implications of the PFOA Stewardship Program on chemical manufacturing
  • Investigate international PFAS regulations and their impact on imports into the U.S.
  • Learn about alternative materials and products that are PFAS-free
USEFUL FOR

Environmental scientists, regulatory compliance officers, public health officials, and anyone involved in the detection and management of PFAS contamination.

United States seems to be PFAS free already. How about the rest of us living elsewhere? How do you detect PFAS? What instruments can you possibly use?

"Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects."

"Certain PFAS chemicals are no longer manufactured in the United States as a result of phase outs including the PFOA Stewardship Program in which eight major chemical manufacturers agreed to eliminate the use of PFOA and PFOA-related chemicals in their products and as emissions from their facilities. Although PFOA and PFOS are no longer manufactured in the United States, they are still produced internationally and can be imported into the United States in consumer goods such as carpet, leather and apparel, textiles, paper and packaging, coatings, rubber and plastics."

That's not what EPA says (what you cite here). It says some PFAS are no longer produced in the US. This does not cover all PFAS, and it doesn't cover imports.
Similar regulations exist in the EU (with a full ban of all PFOA starting mid 2020).
 
As child, before I got my first X-ray, I used to fantasize that I might have a mirror image anatomy - my heart on the right, my appendix on the right. Why not? (Caveat: I'm not talking about sci-fi molecular-level mirroring. We're not talking starvation because I couldn't process certain proteins, etc.) I'm simpy tlakng about, when a normal zygote divides, it technically has two options which way to form. Oen would expcet a 50:50 split. But we all have our heart on the left and our...
