Eine Studie, die die Konzentrationen von Glyphosat und seinem Metaboliten AMPA im menschlichen Urin untersuchten fand eine deutliche Erhöhung im Verlauf des letzten Jahrzehnte:
“What we saw was that prior to the introduction of genetically modified foods, very few people had detectable levels of glyphosate,” said Mills. “As of 2016, 70 percent of the study cohort had detectable levels.”
Of study participants with detectable amounts of these chemicals, the mean level of glyphosate increased from 0.203 µg/L in 1993-1996 to 0.449 µg/L in 2014-2016. The mean level of AMPA went from 0.168 µg/L in 1993-1996 to 0.401µg/L in 2014 to 2016.
