> the safe level is zero.

This is not true of any substance.

> Well it is scary and harmful

Well that narrative certainly came through. The facts supporting it did not.

> Do you work for the chemical industry?

No. Do you? Does this invalidate that the article did not use the opportunity to inform me?

The article has no responsibility of explaining to you why PFAS is harmful, considering its harms are well established in science over many years. Your denialism and ignorance of the harms of PFAS is a malicious attempt to discredit the article. I suggest asking your preferred LLM service with access to the web to find you the necessary evidence.
