Welcome to c/news! We aim to foster a book-club type environment for discussion and critical analysis of the news. Our policy objectives are:

We ask community members to appreciate the uncertainty inherent in critical analysis of current events, the need to constantly learn, and take part in the community with humility. None of us are the One True Leftist, not even you, the reader.

Newcomm and Newsmega Rules:

The Hexbear Code of Conduct and Terms of Service apply here.

  1. Link titles: Please use informative link titles. Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed.

  2. Content warnings: Posts on the newscomm and top-level replies on the newsmega should use content warnings appropriately. Please be thoughtful about wording and triggers when describing awful things in post titles.

  3. Fake news: No fake news posts ever, including April 1st. Deliberate fake news posting is a bannable offense. If you mistakenly post fake news the mod team may ask you to delete/modify the post or we may delete it ourselves.

  4. Link sources: All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. If you are citing a Twitter post as news, please include the Xcancel.com (or another Nitter instance) or at least strip out identifier information from the twitter link. There is also a Firefox extension that can redirect Twitter links to a Nitter instance, such as Libredirect or archive them as you would any other reactionary source.

  5. Archive sites: We highly encourage use of non-paywalled archive sites (i.e. archive.is, web.archive.org, ghostarchive.org) so that links are widely accessible to the community and so that reactionary sources don’t derive data/ad revenue from Hexbear users. If you see a link without an archive link, please archive it yourself and add it to the thread, ask the OP to fix it, or report to mods. Including text of articles in threads is welcome.

  6. Low effort material: Avoid memes/jokes/shitposts in newscomm posts and top-level replies to the newsmega. This kind of content is OK in post replies and in newsmega sub-threads. We encourage the community to balance their contribution of low effort material with effort posts, links to real news/analysis, and meaningful engagement with material posted in the community.

  7. American politics: Discussion and effort posts on the (potential) material impacts of American electoral politics is welcome, but the never-ending circus of American Politics© Brought to You by Mountain Dew™ is not welcome. This refers to polling, pundit reactions, electoral horse races, rumors of who might run, etc.

  8. Electoralism: Please try to avoid struggle sessions about the value of voting/taking part in the electoral system in the West. c/electoralism is right over there.

  9. AI Slop: Don't post AI generated content. Posts about AI race/chip wars/data centers are fine.

So the highest was about 8 ppm. That doesn't really alarm me.

I used to design and perform trace metal assays on incoming raw materials for a factory that made supplements out of powdered botanicals. A typical specification would say "no more than 20 ppm lead". Soil naturally has around 10 ppm lead, so it ends up in practically every plant.

Also think about the doses involved here. How much toothpaste do you consume (swallow) each day. A couple milligrams? Now compare it to the amount food you consume.

Toothpaste would be one of my last concerns.

It does make me question the common advice not to rinse out after brushing though.

[–] bishbosh@lemm.ee 8 points 1 year ago (2 children)

Could rinse with mouth wash work. I assume, perhaps naively, it's less likely to have lead, and it would keep the fluoride present.

[–] quarrk@hexbear.net 7 points 1 year ago* (last edited 1 year ago)

Mouthwash has a much lower fluoride content than toothpaste, so using mouthwash is still removing the fluoride that brushing applied to your teeth. Though I’m not an expert on this, I’m sure there are studies already comparing these two methods.

If you're on city water in the USA, we thankfully have flouride in the water supply. Unless you're in one of those places where the local government took it out.

it got banned across my entire state

Oh, God, that's fucking depressing. I hate capitalism.

My toothpaste I've used for years is in the red and other toothpastes are even worse.

[–] valium_aggelein@hexbear.net 11 points 1 year ago (1 children)

fellow spy kids toothpaste user I see!

[–] anarchoilluminati@hexbear.net 10 points 1 year ago

Honestly, the presence of so many toothpastes for kids is even more angering.

I don't think adults should consume lead either, obviously, but the lack of care capitalists have for kids is just so fucking sickening and makes me so angry. I'll just leave it at that.
