Long-term exposure to tiny amounts of Roundup – thousands of times lower than what is permitted in US drinking water – may lead to serious problems in the liver and kidneys, according to a new study.
The study looked at the function of genes in these organs and bolsters a controversial 2012 study that found rats exposed to small amounts of the herbicide Roundup in their drinking water had liver and kidney damage.
It is the first to examine the impacts of chronic, low exposure of Roundup on genes in livers and kidneys and suggests another potential health impact for people and animals from the widely used weed killer.
“Given even very low levels of exposure, Roundup can potentially result in organ damage when it comes to liver and kidney function,” said senior author Michael Antoniou, head of the Gene Expression and Therapy Group at King’s College London.
“The severity we don’t know, but our data say there will be harm given enough time,” he said.
