Background and purpose: The COVID-19 pandemic swiftly swept across the globe as an infectious disease months after its initial reports. This study aims to identify the factors influencing employees’ adherence to health protocols using the health belief model within the Khorasan Razavi Regional Water Company context.Materials and Methods:In 2019, a descriptive-analytical (cross-sectional) investigation involved 65 Khorasan Razavi Regional Water Company employees. The data collection process involved a meticulously designed questionnaire fashioned by the researcher. This questionnaire encompassed 11, 24, and 18 inquiries about employees’ knowledge, attitudes, and practices. The responses were collected through an online survey platform, followed by meticulous analysis through the employment of SPSS software.Results: : Examination of the interplay between demographic variables and knowledge, attitudes, and behavior constructs revealed that mean scores for knowledge, attitudes, and behaviors did not display any significant variance amongst gender, educational, or occupational categories (p<0.05). Intriguingly, a significant positive correlation emerged between awareness and attitudes (p<0.01), as well as between awareness and behaviors (p=0.02). Other variables exhibited negligible correlation (p <0.05). Furthermore, the outcomes demonstrated that the structure of awareness significantlyimpacted the studied individuals’ behaviors (p =0.01). Employees’ knowledge and attitudes about coronavirus prevention exhibited a commendable standard.Conclusion: This study underscores the pivotal role of employee knowledge and attitudes in shaping their adherence to COVID-19 prevention practices. Consequently, it is recommended that educational initiatives be introduced as potent tools for augmenting the knowledge and attitudes of Khorasan Razavi Regional Water Company personnel.

Abstract Background & Aim: The colored waste from the textile industry is one of the most pollutants in the aquatic environment. One of the most widely used paints in the textile industry is methylene blue, which is often aromatic, often toxic, carcinogenic, mutated and resistant to biological degradation and has harmful effects on living organisms. The purpose of this study was to investigate the bismuth oxyiodide nanoparticles capability to absorb methylene blue from synthetic wastewater. Materials &methods: The present study was carried out in a laboratory scale in batch mode. The effects of variables affecting the process including pH, adsorbent dose, contact time and initial concentration of color, kinetic and adsorption isotherm were investigated. Results: The maximum removal efficiency of methylene blue from solutions was observed in optimal conditions as pH of 9, contact time of 30 minutes, absorbance dose of 3 g/L and initial concentration of 10 mg/L. Methylene blue adsorption compliance by BiOI from a pseudo-second kinetic model and Langmuir isotherm model shows that the type of reaction is chemical absorption. Conclusion: The results of the experiments showed that bismuth oxide has a high potential for removal of methylene blue molecules from contaminated wastewater.
