> Half life [1] in biological systems isn't quite the same as radioactive decay.
It typically is shorter, as real systems are often hyper-exponential. And if you're talking about persistance in isolated clays, then it's by definition is not a bilogical system. A sealed glass vial is technically a type of clay, and glyphosate can survive in sealed vials for decades.
There's a thing about glyphosate: it's the safest pesticide. It's non-toxic to mammals, is not carcinogenic, non persistent, and is highly useful. And this somehow triggers all the cranks because it apparently MUST be hiding something.
And glyphosate has been _extensively_ studied by legitimate scientists.
So at this point, pretty much all articles about glyphosate's harm are pseudoscience and/or transparent grifting.
Clays form a good proportion in some soil profiles in some parts of the world and very much part of the biological system even if it isn't that apparent.
Glyphosate and the by products are certainly safer than many registered herbicides currently available to much of the western world.
The wetter in the formulation of the official Roundup has certainly changed - what I used in the 1990's a few drops of the diluted ready to spray mix accidentally making skin contact would give me a bad headache even if I noticed it right away and washed it off ... when I used the official brand again (for a time, mostly 00's) they priced Roundup out of my farming budget) in the late 10's I noted that I was able to easily wash off any splash back without resulting in a bad headache.
I have been long following the twists and turns that certain big companies, one of which used to own the patent on Glyphosate until 1999 when they let it expire, with a plan to simply create a very large plant in iirc South America which would chase off the competition that have sought to produce Glyphosate for export usage. Unfortunately they put the price up (3x retail here in Australia) due to oil prices costs during the 00's and then China stepped up. I also know they have in place $$$$ BS products to suit their new patented seed which is herbicide ready which when I look over application requirements, complete 100% leaf coverage to work properly implies it is no where near as easy to use as regular roundup.
To be clear I really value Glyphosate as a herbicide as for agriculture it saves fuel, equipment wear and time when used properly. Even so since many are pointing fingers, it is important not to just gloss over any problems that using it might cause, even though I am quite sure there are worse herbicides to be had coming into use having observed this in my immediate locale.
