Impacts of Atrazine on some blood and biochemical indices in farmed Acipenser nudiventris

Abstract

In this study, the effects of the Atrazine were studied on some blood biochemistry parameters in 135Acipenser nudiventris during a 96 hours period. These examinations were made by 4 treatments and each treatment repeated these exams three times with a blank. The amount of LC50-96h of Atrazine was estimated 32.01 mg per liter. Albumin showed significant difference at some concentrations (P<0.05). The Cholesterol level in all concentrations showed significant decrease in comparison with the blank in time. The Triglyceride had its minimum amount in the concentration of 37 mg per liter, which had a significant difference with respect to the blank and some other treatments (P<0.05). Hematocrit percent increased meaningfully with the increase of the Atrazine concentration, and the red blood cells (RBC) decreased meaningfully in different treatments. Hemoglobin showed meaningful tolerance in different times and concentrations. Changes in the average cellular volume had a meaningful difference with the increase of the Atrazine dose and in different treatments and times. The average changes in the hemoglobin corpuscular showed a meaningful difference in different treatments and different times. The average of corpuscular hemoglobin in 24 hours had a meaningful increase in the most of the treatment in comparison with the blank. Neutrophils have increased meaningfully with the increase of concentration and with passing time. Lymphocytes have increased meaningfully with the increase of the Atrazine concentration in comparison to the blank. The monocytes have increased meaningfully in time and with the increase of the Atrazine concentration. According to the table of the toxicity levels, Atrazine is considered as ‘toxic’ for Acipenser nudiventris and we can use the changes in the desired parameters as tools in analyzing the status in the pathobiology of fishes.
