In this study, the effects of the Atrazine on some blood biochemistry indices in Acipenser nudiventris during a 96 hours period was studied. These examinations were made by 4 treatments and each treatment repeated these exams three times with a blank, and these were done on 135 Acipenser nudiventris with the average weight of 50 ±10 g. The temperature, pH and hardness of the water and the dissolved oxygen were 24±1oC, 8, 400 and 7 mg per liter, respectively. The amount of LC50-96h of Atrazine was estimated 32.01 mg per liter. The minimum and maximum level of albumin in treatment 50 mg per liter was observed in the 24th and 48th hour and there was a significant difference (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). The glucose level in all the treatments in 24 hours showed no significant difference with the blank treatment (p<0.05). As time went, the hematocrit increased meaningfully with the increase of the atrazine concentration, and the red blood cells (RBC) decreased meaningfully in different treatments. The amount of the white blood cells (WBC) had decreased meaningfully in the 24th and 48th hour in comparison to the blank. The amount of 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. In some of the treatments the neutrophils have increased meaningfully with the increase of concentration and with time passing by. Its minimum amount has been observed in 96 hours in the concentration of 50 mg per liter. In some of the treatments, with time going by, the amount of the lymphocytes with the increase of the atrazine concentration has increased meaningfully in comparison to the blank. The amount of neutrophils in the 24th and 48th hour showed meaningful increase with the increase of the atrazine concentration and in time, in some of the treatments 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 indices as tools in analyzing the situation in the pathobiology of fishes.
