Bioaccumulation and biomagnification

In my view, this addition would need to be condensed considerably. The text includes general information on bioaccumulation and biomagnification. --Leyo 22:54, 15 November 2023 (UTC)

Yes, we prefer wikilinks to concepts like bioaccumulation and biomagnification. I don´t understand why the review (Houde M, Martin JW, Letcher RJ, Solomon KR, Muir DC (June 2006). "Biological monitoring of polyfluoroalkyl substances: A review". Environmental Science & Technology. 40 (11): 3463–3473) was removed; secondary sources are generally preferred in wp. Feel free to condense the text. JimRenge (talk) 08:49, 16 November 2023 (UTC)

Merge "Economic role" and "Estimated contemporary costs"?

The sections "Economic role" and "Estimated contemporary costs" partly cover the same topic. What about merging the contents in a section called "Socio-economic role"? 195.176.112.14 (talk) 20:14, 23 April 2024 (UTC)

Both sections (as such) do not exist anymore. --Leyo 18:49, 24 June 2024 (UTC)

Presence in Fertilizer

Which section does this go under? ‘This is Chernobyl’: Texas ranchers say ‘forever chemicals’ in waste-based fertilizers ruined their land Hcobb (talk) 18:49, 30 April 2024 (UTC)

Examples

Other than Teflon, that list isn't particularly meaningful to a non-chemist. Maybe list common products that contain these chemicals? 57.135.233.22 (talk) 13:38, 29 May 2024 (UTC)

Unsupported statement in the article

Under the subheading of United States in the section titled "Concerns, litigation, and regulations in specific countries and regions" this statement is made: "but the Republican Party, supported by the U.S. chemical industry filibustered the bill."

I read the article linked as support for this statement. It mentions filibuster once and does not state who did the filibuster. Txantimedia (talk) 07:54, 22 August 2024 (UTC)

The quote from the article is "All legislation aimed at regulating toxic PFAS “forever chemicals” died in the Democratic-controlled US Congress last session as companies flexed their lobbying muscle and bills did not gain enough Republican support to overcome a Senate filibuster." It doesn't say that there was an actual filibuster. I take it to mean if there was a filibuster, there was not enough Republican support to overcome it. So I agree that the wording in the article should be clarified. Nowa (talk) 21:51, 1 September 2024 (UTC)

Even if well-sourced, the factoid may not merit inclusion in this article. It's not really about PFAS themselves. I don't know if this type of political information is appropriate for this article. (It doesn't sound like it belongs in an encyclopedia.) Drsruli (talk) 03:36, 2 September 2024 (UTC)

You raise some interesting points. I agree that the article doesn't need a note about US legislation that didn't pass back in 2021. If we can get someone to second this point, then I'm in favor of removing the paragraph. Nowa (talk) 12:32, 2 September 2024 (UTC)

I agree, not necessary for this article. Should also be removed from intro section. Gahundle (talk) 20:18, 21 September 2024 (UTC)

Inconsistent - PFAS vs. PFASs

Article alternates between using PFAS as plural and PFASs. Should be standardized throughout. I see there was previously a RfC on this topic that did not lead to any changes. I am partial to "PFAS" without plural s, as that seems to be more common in literature (and it's what the group I work with uses, so that helps). Whichever way it goes, a decision should be made and article updated to reflect that. Gahundle (talk) 00:11, 17 September 2024 (UTC)

Leaning towards using PFAS. There are more instances of that being used over the other version, and I haven't seen any instances where PFAS was used to refer to something in the singular. —Tenryuu 🐲 ( 💬 • 📝 ) 01:58, 17 September 2024 (UTC)

Even the OECD in its revised definition (doi:10.1787/e458e796-en) uses "PFAS" as a singular: any chemical with at least a perfluorinated methyl group (−CF₃) or a perfluorinated methylene group (−CF₂−) is a PFAS.
"PFAS" is even sometimes used in singular, when actually the plural is meant, e.g. Where PFAS is found at levels that exceed these standards or If PFAS is detected in your water. When using "PFASs", nobody would use "is" instead of "are". Furthermore, I've seen it several times, that people mistake "PFAS" to be a single chemical, similar to similar-looking acronyms such as PFOS, PFOA etc. This wouldn't happen if "PFASs" was used.
Initially, "PFASs" was used. A few years ago, there was a shift towards "PFAS". Recently, there has been a shift back to "PFASs" by Organisations such as the UN (incl. Stockholm Convention), OECD, but also in the scientific literature.
For the reasons stated, I do strongly prefer "PFASs" (with plural-s). --Leyo 21:32, 17 September 2024 (UTC)

Condensing sections: adverse health outcomes, regulatory concerns, remediation

These three sections are pretty bloated. Health outcomes I think can be reduced to a single paragraph, rather than 7 subheadings. Same idea for litigation and regulation: there are quite a lot of details about litigation from individual US states that I think the breadth of this article does not warrant. Much of this can be condensed, removed, or moved to an article specific to PFAS litigation/regulation. The section on remediation needs a rewrite; it's not organized, it's unclear which technologies are in use and which are under research, or how well developed any of them are. I'm planning to start tackling these when I get a chance, but wanted to give people a chance to weigh in (or beat me to it!) in case there are any strong feelings about any of this.

analytical methods

The following paper could be useful to improve and update the section on analytical methods: Closing PFAS analytical gaps: Inter-method evaluation of total organofluorine techniques for AFFF-impacted water, https://doi.org/10.1016/j.hazl.2024.100122 194.230.145.139 (talk) 23:59, 28 September 2024 (UTC)
