Researchers from NWU’s Environmental Sciences Unit investigated glyphosate and AMPA in South Africa’s environmental samples. The study revealed no detected glyphosate in water, soil, or sediment, though concerns regarding monitoring and regulations persist. Experts suggest further research and farmer input are necessary to assess the herbicide’s environmental behavior.
A recent study from North-West University (NWU) focused on the environmental impact of glyphosate, a commonly used herbicide, in South Africa. Researchers analyzed water, soil, and sediment samples for glyphosate and its byproduct, AMPA. Notably, the study found no traces of these substances in both agricultural and non-agricultural areas within North West and Mpumalanga provinces. Despite the absence of glyphosate, researchers stress the importance of ongoing and sensitive monitoring due to potential environmental risks.
Glyphosate is a major ingredient in herbicides crucial for agricultural practices, especially in crops like maize and soybeans. Its global usage has surged, and in South Africa, it doubled between 2009 and 2017 to around 8,000 tonnes annually. The study, funded by the Water Research Commission, aimed to evaluate glyphosate’s risk to human health and the environment, given its widespread application.
The study indicates a lack of glyphosate in tested areas, suggesting current practices may be safe; however, it emphasizes the need for enhanced monitoring techniques and regulatory frameworks. The risks posed by glyphosate’s inert ingredients remain uncertain, warranting further investigation. Overall, ongoing research is essential to understand glyphosate’s long-term ecological effects in South Africa.
