| Popis: | Glyphosate herbicides are the most widely produced and used herbicides in the world. The intensive applications of glyphosate and its half-life in water result into many aquatic ecosystems. The present study focuses on the evaluation of glyphosate toxicity on the early life stages of the fish Danio rerio. Analysis of the test results revealed that glyphosate is toxic to zebrafish. This effect is marked by the increase in percent mortality at peak concentrations. Long-term exposure to glyphosate affects the hatching rate, heart rate and swimming ability of zebrafish. Significant malformations were observed at the highest concentration in the form of tail bending or fin absence. |
