Acute Toxicity, Chronic Toxicity, D. magna, Four Successive Generations


This present study focuses on assessing the toxicity of glyphosate on Daphnia magna. The first part of this work was devoted to evaluate the acute and chronic toxicity of the herbicide studied according to the Moroccan standards ISO 6341 and ISO 100706. Analysis of the test results revealed that glyphosate is toxic to D. magna. This effect is marked by short-term responses at high concentrations, immobility of juveniles (24h), and chronic disturbances (21d) onthe growth and reproduction of this species. Then, the second part was dedicated to evaluating the toxicity of glyphosate over four successive generations from the F0 mother generation to the F4 daughter generation. The results show that the toxic effect of glyphosate was more pronounced in the F4 daughter generation than in the F0 parent generation.
