Impact of zinc oxide nanoparticles treated dye industry effluent on growth and hematological characteristics of common carp

Zinc oxide nanoparticles were synthesized and characterized by UV-VIS, SEM, EDAX, and FTIR. Different concentrations of zinc oxide nanoparticles such as 20,40,60,80 and 100 mg were prepared for treating dying industry effluent. In this study, different quantities of dye industry effluent on the survival of Common carp as function of exposure time and mortality were analyzed. Based on the acute toxicity test 1/100 (T1), 1/50 (T2), 1/10 (T3) of LC50 value were selected for the sub-lethal test and feed utilization and hematological parameters were estimated after 14 days. The UV-Visible absorption spectra show that ZnO nanoparticles exhibit strong adsorption at 370nm. SEM image shows that the zinc oxide nanoparticles were observed at the wavelength range of 10.81mm (2μm), and 10.8mm (10μm). EDAX spectrum recorded on the zinc oxide nanoparticles is shown as two peaks were located on the spectrum at 1.00 KeV and 8.62 KeV. The FTIR spectrum of zinc oxide nanoparticles was analyzed in the range of 500-4000cm-1. Feed utilization parameters were higher in T3. Haematological parameters such as WBC, Hemoglobin, RBC, Haematocrit and platelets count of Common carp is gradually decreased from T1 to T3 and MVC, MCH and MCHC gradually increased from T1 to T3.
