Environmental Toxicology 2018: Toxicity response of aquatic bioindicators exposed to water polluted with glyphosate

Cristina A. Villamar

Herbicides based on glyphosate (C3H8NO5P / CAS 1071-83-6) have been used (actually close to 150 million kg/year) since 1974 on crop soils to eliminate invasive plant species. Sources water can be reached by this herbicide through runoff, leaching and direct exposure of the water receiving body by aerial application. On aquatic environmental, the glyphosate has been found at concentrations up to 4.0 µg/L.
