Award-winning publicationThe overlooked impact of rising glyphosate use on phosphorus loading in agricultural watersheds

Abstract

The glyphosate-based herbicide most commonly sold as Roundup has received quite a bit of attention due to its potential toxicity to the environment and human health. The research conducted by Marie-Pier Hébert focuses on an environmental impact that has been take too lightly: glyphosate contains phosphorus, and these additional phosphorus loads in agricultural areas run off into aquatic habitats. The study is the first to quantify the inputs of glyphosate‐derived phosphorus by bridging ecotoxicology, biogeochemistry at the soil-water interface and agroecosystem ecology. This innovative contribution in applied environmental sciences could yield significant social benefits.
