Levels of glyphosate, a controversial chemical found in herbicides, markedly increased in the bodies of a sample population over two decades, a study published Tuesday in a US medical journal said.
The increase dated from the introduction of genetically-modified glyphosate-tolerant crops in the United States in 1994.
The findings published in the Journal of the American Medical Association (JAMA) came as the European Commission proposed on Tuesday to renew the license for glyphosate for a shorter than usual five to seven years.
That decision by the EU’s executive arm followed a growing uproar over the alleged danger of its use.
Researchers compared the levels of glyphosate in the urine of 100 people living in California. It covered a 23-year period starting from 1993, the year before the introduction of genetically-modified crops tolerant to Roundup.
