The notable increase in the use of zinc in different forms has led to environmental concerns regarding this element. In this study, three different forms of zinc metal, including zinc heavy metal zinc, zinc chemical and green synthesized nanoparticles were evaluated on blood indices of common carp for 21 days. 420 carp juveniles were divided into 7 experimental groups T0 (control), T1 and T2 (1.5 and 2.5 mg per liter of zinc heavy metal), T3 and T4 (1.5 and 2.5 mg per liter) liter of chemical zinc nanoparticles), T5 and T6 (1.5 and 2.5 mg/liter green zinc nanoparticles), and blood parameters were evaluated. Accordingly the hematocrit percentage in T1 and T2 treatments, the number of red blood cells in T2, T4 and T5 treatments, the amount of hemoglobin in T2, T4, T5 and T6 treatments and the amount of MCH only in T6 group showed a significant decrease compared to the control group (P>0.05). The lowest amount of MCHC was recorded in T4 (19.23 ± 1.60), T5 (18.61 ± 2.33), and T6 (18.48 ± 4.80) treatments. In addition, the amount of MCV in T1 recorded a significant decrease compared to the control group (P<0.05). The number of white blood cells exhibited a significant decrease in all treatments except 1.5 mg/liter green zinc nanoparticles compared to the control group (P<0.05). The lymphocyte percentage also illustrated a significant decrease in T1, T2, and T3 treatments as compared with the control group (P< 0.05). In contrast, the monocytes percentage in the groups exposed to the heavy metal showed a significant increase compared to other treatments. Also, the neutrophils percentage in T1, and T2 groups recorded a significant increase compared to the control and green zinc nanoparticles groups (P< 0.05). These results may be related to the adverse effects of zinc (in different forms) on hematopoietic tissues, weakness in using dietary iron, and hormonal fluctuations that led to adverse effects on blood parameters. Therefore, based on the findings of this study, zinc metal even in its green form can have adverse effects on the blood parameters of carp fish.
