New research from McGill University reveals an overlooked impact that the widely used herbicide glyphosate may be having on the environment.

First commercialized by Monsanto under the name Roundup, glyphosate has come under scrutiny in the past, mostly in relation to its potential toxicity. This new research, published recently in the Ecological Society of America’s Frontiers in Ecology and the Environment, focuses not on direct health risks associated with the herbicide, but on its contribution to environmental phosphorus levels, an issue that has yet to receive much attention.
