Glyphosate: Las consecuencias no pueden ser calculables ni imaginables

Sebastião Pinheiro*


Amigos y ciudadanos, en los últimos 25 años surgieron y expandieron cultivos genéticamente modificados,principalmente para incrementar el uso de herbicidas a base de Glyphosate y Glufosinato.


El resultado es que millones de hectáreas de áreas cultivadas están infestadas por malezas mutantes resistentes a estos herbicidas que ya superan a más de 300 espécies en el mundo. Las consecuencias no pueden ser calculables ni imaginables.

Es raro en el mundo agua libre de contaminación por estos herbicidas y lo más grave es el hecho de la ciencia callar ante el grave y severo riesgo de formación de varias nitrosaminas de glyphosate y nitrosaminas de glufosinato de altísima toxicidad y capacidad de provocar cáncer por actuar, también como aminoácidos sintéticos de condiciones muy adversas en Biología.

El gobierno de California el 16 de junio de 2017 oficializó el riesgo de contaminación por nitrosaminas:

The government of California on June 16, 2017 made the risk of contamination by nitrosamines:

Glyphosate Listed Effective July 7, 2017, as Known to the State of California to Cause Cancer

Jun 26, 2017

On March 28, 2017, the Office of Environmental Health Hazard Assessment (OEHHA) posted a Notice on its website[1] that glyphosate (CAS No. 1071-83-6) would be added to the list of chemicals known to the state to cause cancer for purposes of Proposition 65[2] with a delayed effective date due to the pending case Monsanto v OEHHA.[3]

Monsanto’s challenge was unsuccessful in the trial court. Although the case has been appealed, no stay of the listing has been granted. Therefore, glyphosate is being added to the Proposition 65 list on July 7, 2017.

In summary, glyphosate is listed under Proposition 65 effective July 7, 2017 as known to the state to cause cancer, as follows:

Chemical CAS No. Endpoint Listing Mechanism*

Glyphosate** 1071-83-6 Cancer LC

*Listing mechanism: LC – “Labor Code” mechanism (Health and Safety Code section 25249.8(a) and Title 27 Cal. Code of Regs. section 25904)

** The International Agency for Research on Cancer (IARC) indicates the following chemicals are “also relevant: 38641-94-0 (glyphosate-isopropylamine salt) 40465-66-5 (monoammonium salt) 69254-40-6 (diammonium salt) 34494-03-6 (glyphosate-sodium) 81591-81-3 (glyphosate-trimesium)” (IARC, 2015b), because these salts dissociate to free glyphosate.

Friends and citizens, in the last 25 years have emerged and expanded genetically modified crops, mainly to increase the use of herbicides based on Glyphosate and Gluphosinate. The result is that millions of hectares of cultivated areas are infested by mutant adventitious herbs resistant to these herbicides that already surpass more than 300 species in the world. The consequences can not be calculated or imaginable.

It is already rare in the world water free of contamination by these herbicides and the most serious is the fact that science is silent on the serious and severe risk of formation of various nitrosamines of glyphosate and nitrosamines glufosinate of very high toxicity and ability to cause cancer by acting, also as synthetic amino acids from very adverse conditions in Biology.

The government of California on June 16, 2017 made the risk of contamination by nitrosamines:
