Alarm bells over toxic farm chemicals in SA water
SA and Norway researchers find high levels of a toxic herbicide in water bodies surrounding maize fields
Scientists have raised a red flag after finding high levels of toxic farm chemicals in local rivers and dams close to where genetically modified (GM) maize is commonly grown.
In a research paper published in the SA Journal of Science on Thursday, a group of researchers from SA and Norway said they had found high levels of the toxic herbicide 2,4-D in several water bodies surrounding maize fields on the border between the Free State and North West.
Dr Suranie Horn and Rialet Pieters of North West University in Potchefstroom and Thomas Bøhn of the Institute of Marine Research in Tromsø, Norway, said the concentrations of 2,4-D far exceeded the European Union (EU) guideline for drinking water, and this indicated “a risk to people using these water sources”...
