Glyphosate

Here : http://seaus.free.fr/spip.php?article27 "Il se retrouve presque systématiquement dans les rivières mais désormais aussi dans les eaux souterraines, où 20 % des prélèvements l'ont mis en évidence." Sorry for non-french readers Still no levels stated (as, for example, ng/ml). Even the third paragraph in "Faune menacée", which states the toxic level to fish, does not give actual levels found. You can also find some interest in readind : http://www.ifen.fr/acces-thematique/...ncontrees.html knowing that AMPA is the result of degradation (not sure of the word in english) of glyphosate. Just have a look at the graph... amazing. Indeed. Many toxic substances were found. It's not good, but without actual levels no real conclusions can be drawn. Analytical methods are now so sensitive that many chemicals can be detected at extraordinarily low levels - far below what would be considered toxic. Yet, they would appear in that graph as they had been detected. -- Jeff |
