Effects of Low Concentration of Glyphosate-Based Herbicide on Genotoxic, Oxidative, Inflammatory, and Behavioral Meters in (Teleostei and Cyprinidae).

The glyphosate herbicide is a pesticide widely used in the world and can contaminate soil, air, and water. The objective of this work was to evaluate the toxicity of a glyphosate-based herbicide (GBH) in zebrafish (). Fish were exposed to different concentrations of GBH (0, 50, 250, and 500 g/L) for 96 hours.
