In 2015, the University of California – San Francisco started conducting a study about glyphosate in humans after it has been classified as carcinogenic by the United Nations.
The results, as published only last month, indicated that at least 93% of urine samples, tested in the early phase of the study, contain certain levels of carcinogenic glyphosate.
The question now is: are these field exposure levels of the chemical fall within the safe levels previously published?
Is there really a true level of safety when it comes to manmade chemicals?
Glyphosate was found in 93% of the 131 urine samples tested at an average level of 3.096 parts per billion (PPB). Children had the highest levels with an average of 3.586 PPB.
The regions with the highest levels were the West and the Midwest with an average of 3.053 PPB and 3.050 PPB respectively.
Glyphosate residues were not observed in any tap water samples during the early phase of the project, most likely due to phosphorus removal during water treatment.
