| Abstract | ||
| When Cyprinus carpio was exposed to different concentrations of glyphosate 2.5, 5.0, 6.5, 7.5, 8.5, 9.5, 10 ppm for 72 hrs at 25 – 27 C. The Lc50 was 8.5 ppm on acute exposure. We used serological test that included Glutamic Oxaloacetic Transaminase (GOT), Glutamic Pyruvic Transaminase (GPT), Alkaline Phosphatase and total protein estimation to determine the biochemical effect of herbicide in the serum of Cyprinus carpio. The test have performed after 7, 14, 21, 30 and 60 days of the acute and chronic exposure to 5.0 and 0.25 ppm in addition to control group .The results showed an increase in GPT, GOT and Alkaline Phosphatase enzyme values after one week and still after two mouths of exposure to glyphosate .The chronic exposure was more effective than acute exposure, while there were a decrease in total protein concentrations after two weeks of glyphosate exposure. | ||
