accidentally exposed or something. "Significant" is also vague and subjective, so it's better to "show not tell" and give the actual number. Something like this would be less vague: "Epidemiological studies find the opposite response in humans; an exposure of X is statistically correlated with a Y increase in total cholesterol and a Z increase in LDL cholesterol." The rest of that sentence seems to assume that the relationship is causal, rather than allowing that correlation does not prove causation and saying something like: "If PFOS exposure actually causes higher cholesterol, this would indicate..." --
290: 269: 822:...especially, as a citation reference is given for that sentence. The entire point of the article is that there are undetermined correlations without established causality or mechanism; connections have been documented without the exact nature of them being known. This, necessarily, falls into the territory of "vagueness". Therefore, there is no reason to cast doubt upon a simple, self-evident statement (one which has a reference) by hanging a "vague" tag on it. Discussion? 1752:
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.

self-published by C8SciencePanel.org. C8SciencePanel.org is registered anonymously, but appears to be owned by a plaintiff's law firm with a financial interest in PFAS litigation. Knowledge's editorial standards say that content "must be verifiable." The C8SciencePanel.org position papers are not verifiable. That Table should be deleted.
1419:. 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. 1239:
Of course: "It contains analysis, evaluation, interpretation, or synthesis of the facts, evidence, concepts, and ideas taken from primary sources". In this case the primary sources are the historical documents that they reviewed. It was published in a peer reviewed journal and is on PUBMED. So it is

I don't think it's particularly required to be a medical expert in order to point out a phrase that is not clear to a general audience, but I do actually have a science background. Thanks for pointing out this thread, but it would be helpful to direct your comments to the merits of the text, rather

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
1578:
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
870:
I don't have access to the referenced article, so I can't clarify whether the association is based on epidemiology that indicates a statistical correlation that may or may not indicate causation, medical studies that were testing PFOS as a treatment, or case reports from people who had just been
1289:“manipulation of the research question to obtain predetermined results; funding and publishing research that supports industry interests; suppressing unfavorable research; distorting the public discourse about research; changing or setting scientific standards to serve corporate interests;" 776:
Echoing the previous comment, the page provides a Table titled "Probable links to health issues as identified by the C8 Science Panel." The Table lists position papers that did not meet the quality standards for publication in a reputable peer-reviewed scientific journal, and thus were
1722:. 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. 1594:
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.)
1559:
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."
721: 190: 153: 1610:
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.
1453: 1263:
They also "developed deductive codes to assess industry influence". And this "development" is original work (primary research). The review element pertains to determining document dating, so far as I can see.
1284:
Drawing on the work of Bero and White , we deduced six codes from the cross-industry strategies of manipulation that researchers previously established to see whether the same practices emerge among the PFAS

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.
1651:, 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. 44: 147: 1519: 1647:
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.

The publisher categorize this as an "Original Article", but PUBMED has it as a review. On inspection, it's a composite of both. So, the question is: is the cited material

Bits are primary and bits are secondary, as for many sources. However looking with that in mind the bits you added seem to be secondary, so there is not an issue.

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
