EFFECTS OF ACUTE AND CHRONIC EXPOSURE TO GLYPHOSATE ON COMMON CARP (CYPRINUS CARPIO L.) HEMATOLOGICAL PARAMETERS: THE BENEFICIAL EFFECT OF PROPOLIS

摘要

Glyphosate, a non-selective and broad-spectrum herbicide, is widely used for plant control in terrestrial and aquatic environments. The objective of this work was to evaluate the effects of this herbicide on blood parameters of the common carp (Cyprinus carpio L.), adult fish, which were acutely and chronically exposed (4 and 21 days) to 6 and 12 mg L~(-1) of glyphosate. In this study, a significant increase was determined in the number of total leucocyte count and agranulocytes for both acute and chronic exposure to glyphosate. On the other hand, granulocyte and erythrocyte count, hemoglobin level, hematocrit, mean corpuscular volume and platelet were significantly decreased in both acute and chronic exposure to glyphosate (p< 0.05). Experimental results indicated that the changes occurring in hematological parameters depending on the dose and duration were compensated by propolis.
