In this study, a nanostructure adsorbent was fabricated from mixed nanosized zero‐valent iron (nZVI), chitosan (CS), and copper (Cu) for the simultaneous removal of Reactive Violet 5 and Reactive Blue 171 from the aqueous media. The prepared adsorbent was characterized by scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, Brunauer‐Emmett–Teller, Fourier transform infrared spectroscopy, and X‐ray diffraction. The impact of variables, including pH, adsorbing dosage, contact time, and temperature on the removal percentages of RV5 and RB171 dyes were simultaneously investigated using response surface methodology (RSM) based on a central composite design. The maximum removal efficiency (77.67 %) was obtained at a pH of 3, an adsorbent dosage of 0.3 g, a contact time of 15 min, and a temperature of 10 °C. The adsorption process fitted well with the Langmuir isotherm model with a coefficient of determination (R2) equal to 0.9996 and the pseudo‐second‐order kinetic model (R2=0.9988). Hence, it could be concluded that the process of adsorption mechanism is monolayer and chemical. The maximum adsorption capacity (qmax) was 50.25 mg g−1. In conclusion, nZVI‐CS‐Cu can be considered as an efficient and inexpensive adsorbent for dye removal from aqueous solutions, because its separation is quick and easy, it possesses high efficiency, and there is no secondary pollution.

: According to the results obtained thus far, ozone/magnetic copper ferrite nanoparticles (CuFe2O4 MNPs)/potassium hydrogen monopersulfate (KMPS) is capable of totally degrading 20 mg/L diazinon (DZN) with 6 mg/L ozone, 0.6 g/L KMPS, and 0.1 g/L MNPs at pH = 7 in 20 min. The experiments showed that the concentrations of KMPS and MNPs were more effective than ozone on the system efficiency. Moreover, high concentrations of KMPS and MNPs were not very effective in DZN degradation. Furthermore, the degradation efficiencies of diazinon at pHs 3, 4, 5, 6, 7, 8, 9, and 10 were 94%, 95.35%, 97.45%, 98.15%, 99.2%, 99.3%, 99.3%, and 100%, respectively. The pH of the solution was effective on the system so that in the range of 7 - 10, the system had high efficiency. Even within the range of 3 - 6, the pH had not been so plummeted, resulting in a high percentage of DZN degradation. Besides, MNPs could be utilized in the system for up to five cycles without any loss of catalytic activity. The degradation efficiency of diazinon was 99.2% in the first use and 92.1% in the fifth use. Also, the process efficiency was assessed in four real environments showing that agricultural drainage and urban wastewater with the degradation percentages of 79.1% and 77.3%, respectively, were better treated than the urban and river water with the percentages of 93% and 88.4%, respectively. With the determination of active agents in the reaction using the scavenging agents, it was recognized that sulfate radicals, hydroxyl radicals, superoxide, and singlet oxygen contributed to DZN degradation. By the way, ozone was advantageous to both singlet oxygen and superoxide in the degradation of diazinon.

“…Diazinon (O, O-diethyl-O-[2-isopropyl-6-methyl-4-pyrimidinyl] phosphorothioate) (DZN) is an organophosphate insecticide; although since 2004, the United States Environmental Protection Agency banned the domestic usage of diazinon, it is still widely used in agriculture and even for domestic purposes in developing countries (Montuori et al, 2015). Some features of diazinon, including moderate mobility and solubility in water, and its stability in the soil have made it a hazardous pollutant for surface water and groundwater (Farhadi et al, 2021). Various environmental and pathological effects of diazinon have been demonstrated (Aggarwal et al, 2013).…”

Diazinon exposure reduces bone mineral density in adult and immature rats: A histomorphometric and radiographic study

et al. 2021

Diazinon has been widely used as a domestic and agricultural pesticide. This study examined the effects of diazinon on bone mineral density (BMD) of mature and immature rats. For this purpose, 24 adult Wistar rats (male; 8 weeks old) were initially divided into four groups ( n = 6). Corn oil was used as the control while diazinon at 15, 30, and 45 mg/kg in corn oil was given to mature rats via gavage per day. Since these dosages were lethal for the immature rats, 12 immature Wistar rats (male; 4 weeks old) ( n = 6) were gavaged with corn oil as control and 5 mg/kg of diazinon in corn oil. The animals were sacrificed on day 28 with their left femur bones removed for histomorphometric studies. BMD was measured in the right femur, using standardized radiographs in the femoral head, femoral neck, greater trochanter, and shaft. The Image J Program was used for measuring the bone lamellae and epiphyseal growth plates. The results of this study for the first time revealed that diazinon reduced BMD in both adults and immature rats. Diazinon exposure was associated with diminished trabecular and cortical bone density. Correspondingly, our results indicated that in immature rats, DZN led to the reduction in the epiphyseal growth plate width, both in the proliferation and hypertrophic zones. These results suggested that diazinon might be associated with impaired bone longitudinal growth as well as bone metabolism in adults.
