  A new nano adsorbent was prepared using zinc oxide nanoparticles supported on graphene oxide to separate copper from electroplating industry wastewater. Graphene oxide was synthesized via Hummer's modified method, and its surface morphology was characterized through FTIR spectroscopy and scanning electron microscopy (SEM). A systematic study of the adsorption process was conducted, varying pH, initial copper concentration, contact time, adsorbent dosage, and temperature. The experimental results revealed that the maximum adsorption capacity, with 89.77% efficiency, was achieved at a pH of 7 when 0.5 g of adsorbent was in contact with a 200 mg/L copper solution at 20°C for 30 minutes. The nano adsorbent exhibited a high adsorption capacity in both simulated and real industrial wastewater samples, effectively removing up to 99% of copper from industrial samples. Adsorption isotherm, kinetic, and thermodynamic studies were performed to elucidate the adsorption mechanism. The adsorption process followed pseudo-second-order models and the Freundlich isotherm. Thermodynamic studies indicated that the adsorption of copper ions on ZnO/GO was a spontaneous and exothermic reaction with an enthalpy of -6361.21 J/mol. This study demonstrates that nano ZnO/GO can be utilized as an effective, low-cost, and environmentally friendly nano adsorbent for electroplating wastewater treatment. Manuscript profile

  The effect of zinc oxide nanoparticle as a mineral supplement in the diet on the white blood cells of rainbow trout was investigated in this research. Eight hundred specimens of rainbow trout fry (17.22±5.41 g) were randomly distributed in 18 experimental tank (six treatments each with three replications). The basal diet was prepared without zinc supplementation and used for the negative control treatment. Other experimental diets were prepared by adding 10, 30, 50 and 70 mg/kg of zinc nanoparticles and 70 mg of zinc sulfate (positive control) to each kg of the basic diet. Blood samples were taken from the fish at the end of the experiment to check the number of white blood cells and their differential count. After two weeks of adaptation, the fish were fed for 8 weeks with the diets corresponding to each experimental treatment. Blood samples were taken from the fish at the end of the experiment to check the number of white blood cells and their differential count. The results showed that nano zinc oxide has a significant effect on the leukocyte count with the highest number of 178,000±22,000 No. mm-3 in fish fed diet supplemented with 50 mg kg-1 Nano ZnO, which was significantly more than their number in fish fed with basic diet (p<0.05). Furthermore, fish fed diet supplemented with 50 mg kg-1 Nano ZnO diet had the highest lymphocytes percentage of 72.21±0.13%, while the lowest percentage of neutrophils was also found in fish fed diet supplemented with 50 mg kg-1 Nano ZnO. However, the actual number of neutrophils in the blood of fish in this treatment was 4.5 folds more than those in the negative control treatment. Findings of the present study showed that zinc oxide nanoparticles have a significant effect on the leukocyte properties of rainbow trout. Manuscript profile

  Unsuitable water quality and pollutants in the water causing stress response and eventually occurs on physiological parameters of fish health and reduced immune function of fish, hence the use of vitamins seems like a very necessary safety supplier for improve immunity. 170 pieces of fish with an average weight of 170 grams was taken at 70 L tanks. Then fish were placed in 40 and 80 mg per liter concentrations of nanoparticles on two levels of vitamin C (400 and 800 mg per kilogram of food). Compatibility during was performed twice feeding during this period fish with commercial food were fed at a rate of 2% body weight per day. The water used in the workshop physicochemical factors including temperature C ° 20 ± 2, pH 7/2 ± 0/4 and dissolved oxygen 6/74 ± 0/2 and water hardness 185 ± 16 ppm was measured on a daily basis and fixed in all treatments were considered. The combination of 800 mg/kg of vitamin C and 40 mg/l of Nano simultaneously taking the cause of the protective effect of vitamin C by Nano zinc on liver damage so that damages were lower compared with other treatments. This study shows that the use of a suitable material such as vitamin C at high concentration, 800 mg per kg in the diet of rainbow trout, seems to be necessary and useful for increasing the antioxidant defense.

  The increased industrial applications of nanoparticles increase the possibility their deposition into aquatic ecosystems and thereby threatening the aquatic life. Therefore, this study aimed to provide the toxicological effects of ZnO NPs (0, 1,2,4,8 mg.L-1) on certain hematological indices of Koi fish for a period of  2 and 10 days, under static bioassay. A significant decrease in hemoglobin (Hb) content 7.3±0.19, red blood cell (RBC) count 1.41±0.03, hematocrit (Hct) value 22±0.66, mean cellular volume (MCV) 155.35±5.29 and mean cellular hemoglobin (MCH) 51.2±2.07 (except on 4 mg.L-1dose) was noticed throughout the study period of 10 days when compared to control groups. In contrast, mean cellular hemoglobin concentration (MCHC) levels 4±0.23 were found to increase during the study period.Our results demonstrate that high ZnO NPs concentrations in the aquatic environment may have adverse effects and cause acute changes on hematological parameters of Koi fish.

  Nanotechnology is a term which refers to all advanced technologies of Nano scale. By Nano scale, a dimension of 1-100 nanometers is presumed. Nano zinc oxide is one of the most important nanomaterials which is widely used in business and industry and this has caused some concerts regarding its effect on the environment and human health. There are not many studies of harms of these materials to the body. The present study was done to define the role of zinc oxide nanoparticles and its deposition values in lung. Syrian female mice of NMRI variant were divided into three groups of 10 each: control, 1000 ppm/kg zinc oxide nanoparticles and 2000 ppm/kg zinc oxide nanoparticles treated groups. During a period of 10 days, different doses of zinc oxide nanoparticles (i.e. 1000 and 2000 ppm/kg) were given to treated groups by inhalation, the control group received distilled water by inhalation. Then the mice were dissected and lung was prepared for investigation of zinc oxide nanoparticles deposition by Atomic Absorption Spectrometer. Statistical analysis showed that zinc oxide nanoparticles had significant difference in tissue of the lung which had received doses 1000 and 2000 ppm/kg compared with control group. Consumption of zinc oxide nanoparticles in doses of 1000 and 2000 ppm/kg, deposition of this material significantly increased in lung. Manuscript profile

  In this study the direct absorbance of Nano zinc oxide by a bivalvia (carbicula fluminea) tested in 48 h as short time period. The bivalvia stock with initial mean length 2.5 + 0.9 cm were gathered from nature resources and transferred into laboratory and distributed in 10 aquariums. Nano particles were  spread in oltrasonic with 400 rpm. The tanks water was emulsioned with nanoparticles by homogenizer in 14000 rpm. The treatments were exposed to 0.25, 2.5 & 25 ppm nanoparticles. The Nano zinc oxide stocks in bivalves tissue and their distribution were measured by ICP & DLS. The results showed that the most nanoparticles were observed in the treatment which exposed to 0.25 ppm pollution ( p <0.05) and the less absorbance was seen in the treatment which exposed to 25 ppm (p<0.05). The DLS test showed that the nanoparticles size was between 10-100 nanometers which confirmed that the nanoparticles were homogenized and didn’t sequestrate. In  conclusion, the observance by bivalvia can be a benefit index for measuring the Nano zinc oxide's pollution in water. Manuscript profile
