PFAS and micro plastics, we know nothing, again.

[BeyondKnowledge]

PFAS and micro plastics, what was recently discovered that we now know nothing about the test results.

Yes, all the hype is about bad lab work. Testing labritories use gloves with a release agent that memics positive test results for PFAS chemicals and micro plastics. 

I am not saying it is not bad but no one has any accurate numbers any more. The ones doing the testing were in fact contaminating the samples with their glove dust. 

This was recently measure in a lab to be 1000 times what it should have been after a complete cleaning of the lab.

Have some links to chew on. The lawyers certainly will.

So, now we know nothing again about the contamination levels. Everyone from the lawyers to the locals are not going to like this.

All I can really come away with is the general casual attitudes about making inflammatory claims, only to find out the more than one lab may have been processing the task without stringent discipline and methods... or perhaps just got the results they certainly expected to see and stopped there.

This is one of those "fixed the barn doors, after the cows came home" deals...

The gold star comes from accurate data without distortion or error...

By misrepresenting the results (even accidentally,) activists hinging their terror-porn on it, harm more than only research.

[BeyondKnowledge]

I see it as a lot of the lawsuits being thrown out. Many going on for years, some over ten years now. All because there is no credible evidence any more of anything other then bad lab work. 

All those lawyers will have to start over after new testing with new procedures in place for these particular tests. 

I see this doing to the activists much like what COVID did to medical trust. Then again, it was always about the lawyers and what they promised to get form the corporations.

Bad lab procedures gave the corporations a do over card for free. There might not be enough evidence to refile again in some cases.

It appears not all studies were contaminated in this way.

"No, not all microplastic studies are contaminated, though a recent University of Michigan study indicates that standard nitrile and latex gloves can cause significant overestimations in specific research contexts.  The contamination stems from stearate salts, non-plastic residues used to coat gloves for easy removal, which chemically resemble polyethylene and create false positives at a rate of approximately 2,000 particles per square millimeter upon contact with samples. 

• Scope of Contamination: The issue specifically arises when researchers use standard gloves that shed stearates, which can be mistaken for microplastics by vibrational spectroscopy (Raman or infrared) due to their similar chemical fingerprints. 
  
• Mitigation Strategies: Researchers can avoid this contamination by avoiding glove use entirely where safe, or by switching to cleanroom gloves manufactured without stearates, which produce significantly fewer false positives (around 100 per square millimeter). 
  
• Data Recovery: Scientists have developed new statistical methods and spectral libraries to differentiate between true microplastics and stearate contamination, allowing them to recover and correct older datasets that may have been affected by this source of error. 
  

While the study highlights a widespread potential for error in current protocols, it does not suggest that all existing data is invalid or that microplastic pollution is non-existent; rather, it emphasizes the need for refined methodologies to ensure accuracy. "

I certainly hope most of those studies have overestimated plastics contamination and accumulations in our bodies.

Well synthetic materials for gloves were a profit boon...
Those who 'always used those gloves' better monitor themselves...
just in case.

Now old-fashioned rubber gloves will be in demand again...
And Eco-activist will declare there's too much rubber in our food.

Rinse, repeat.

Sorry for the spurious cynicism... just wishing this kind of 'convenient' error in public affairs actually was prevented by scientists, rather than 'enjoined' when subsidized by wealthy speculators.

Please explane that to the lawyers and the legal system. They only understand the numbers are now bad. 

One side is happy they are getting a do over card while the other is betrayed by the science. Both sides are seeing more dollar signs in their future because of this development.

You are saying they don't use modern synthetic mold release agents when making latex gloves? Do you have any proof.

In a recommendation on Google search, environmentalists want to put even more PFAS in your land, water and food.

Even if the numbers are no where near as bad as they said they are, why keep doing it?

[ReturnofBroccoli]

Maybe its time people really start utilizing all of their space to grow their own food, raise some chickens and other things. At the very least your own spices. We grow spices. If everyone grew their own stuffs we could all trade with one another ^.^

Beware of soap that really isn't soap, like Dove, Dial, Axe, Irish Spring etc. By law they are not permitted to use the word 'soap' but some companies sidestep the law with certain wording. It is not soap, what you are using are forever chemicals, endocrine disruptors, and carcinogens which are absorbed through your skin and get into your blood steam to forever accumulate in your organs and tissues. There are natural saponins out there with no plastics, petroleum or chemicals, such as the plant soapwort which ancient peoples used until recent times, until Tide introduced detergents in the early 20th Century.

They keep doing it because they make Billions of dollars catering to our vanity or misleading up into believing their products are safe and better.
