Long-term intake of the Monsanto's most popular Roundup herbicide, even in very small amounts lower than permissible in US water, may lead to kidney and liver damage, a new study claims.
The research, conducted by an international group of scientists from the UK, Italy and France, studied the effects of prolonged exposure to small amounts of the Roundup herbicide and one of its main components – glyphosate.
In their study, published in Environmental Health on August 25, the scientists particularly focused on the influence of Monsanto's Roundup on gene expression in the kidneys and liver.
In the new two-year study, which extended the findings from one conducted in 2012, the team added tiny amounts of Roundup to water that was given to rats in doses much smaller than allowed in US drinking water.
Scientists say that some of the rats experienced "25 percent body weight loss, presence of tumors over 25 percent bodyweight, hemorrhagic bleeding, or prostration."
