Paper 1: 'no cytotoxic effects at concentrations at or below 100 μM' -- A non trivial amount.
(Sorry don't have the full text for the others)
And your 'worst one of all' is a joke of a paper. Its a review and begs the question that glycophosphate is substituting an amino acid.
Its presupposition that
” Glyphosate is a glycine molecule with a
methyl-phosphonyl group bound to the nitrogen atom. As
an analogue of glycine, it can be expected to displace
glycine at random points in the protein synthesis process,
with unknown consequences.
Demonstrates a clear lack of understanding of the specificity of the ribosomes and enzymes/proteins in general.
Of course they have no actual evidence - say isolating glycophosphate substituted proteins? Fairly easy to do as normal proteins do not contain phosphorous, or it could be via C13 labeling of the what would be the glycine residue.
To say nothing that its quoting studies dosing the equivalent (10mg+/kg) of having a person do literal shots of herbicide.
Everything (except e-caprolactam, go figure) causes cancer, and most everything will kill you if you have enough of it. Hell the IARC has glycophosphate in the same category as red meat and drinking beverages warmer than 65C. They've also classified cell phones as 'possibly carcinogenic to humans'. http://www.iarc.fr/en/media-centre/pr/2011/pdfs/pr208_E.pdf
