(Natural News) A scientific study has reaffirmed that a popular weedkiller manufactured by Syngenta and used on crop fields all across the United States is so damaging to the endocrine system that it can actually turn natural-born males into females.
Published in the journal Proceedings of the National Academy of Sciences, the paper by researchers from the University of California, Berkeley found that African clawed frogs (Xenopus laevis) exposed to just 2.5 parts per billion (ppb) of atrazine for three years – a level below the 3 ppb allowed by the Environmental Protection Agency (EPA) in human drinking water – ended up losing their maleness and becoming chemically castrated.
