Study Examines How Glyphosate Contributes to Environmental Phosphorus Levels

Research from McGill University shows that the herbicide glyphosate is contributing to environmental phosphorus levels in soil and waterways. The study was published in Ecological Society of America’s Frontiers in Ecology and the Environment. As global use of glyphosate has increased 15-fold over the past 20 years, the small amount of phosphorus in glyphosate has begun to add up, researchers report. “Our study argues that the recent and rapid rise in glyphosate use has magnified its relative importance as a source of anthropogenic phosphorus, especially in areas of intensive corn, soybean, and cotton cultivation,” lead study author Marie-Pier Hébert says.
