"And this is not at extremely high concentrations" said co-author of the review Val Beasley of the University of Illinois in a press release. "These are at concentrations that are found in the environment."
Humans aren't spared the effects of atrazine, the world's second most common herbicide after glyphosate, Hayes said.
Hayes pointed to studies correlating atrazine exposure to low sperm quality, birth defects, miscarriage, and breast cancer
"The hotspot is probably the US, because we use so much" Hayes said. "The biggest hotspot in the US is the Midwest, the cornbelt, another is Florida where it is used on sugar cane."
But, he added, "We're all exposed to it. Surface water, rainwater you name it atrazine is in it."
The European Union has already banned the use of atrazine "I think a global ban is certainly in order" Hayes said.
The maker of atrazine, Switzerland-based Syngenta, disagrees "The science is clear. Atrazine cannot, does not, and will not cause adverse effects at levels to which people would ever be exposed in the real world" Ann Bryan, Syngenta's senior manager of external communications told Discovery News.
