This research, descriptive, is a mix of on-desk studies, observation and collection and recording of information and opinions of experts, whichafter evaluating internal factors (strengths and weaknesses) and external factors (opportunities and threats), the data are entered into the IFE and EFE matrix.SOWT analytical methodwas used to evaluate the ability and management deficiencies of prevention and coping with abnormal conditions of Ardabil University of Medical Sciences. The results of internal factor analysis showed a score of 2.54, which indicates that the university’s passive defense management has a positive performance in using strengths to eliminate weaknesses, and a score of 2.48 indicates poor performance in using opportunities to deal with threats.Also, the results of the strategic quantitative planning matrix of passive defense management of the university, based on their overallweight in movement correction, have adopted a competitive strategy (ST). Strategies for preparing information and general plans in all fields (university funds) using companies, specialists and experienced experts for all national and strategic researchesand projects and proper planning to attract the credit of the ministry and donors and other local institutions, to support and provide servicefor critical situations along with updating depreciated centerswithwiderthreats in crowded urbanareaswas discussed and it was proclaimedthat by increasing the capacity of the hospital by creating suitable spaces and completing the field hospital and coordinating the use of sports and educational facilities ,creatinga shed or warehouse and storing medicine and equipmentfor use in emergencies isofmoreattraction.Accordingly, the university directors, to mitigate threats, should plan and strive in earnest and turn them into chancein such a way to provide for readiness ofCBRNE teams and use appropriate programs to increase the awareness of staff and individuals in the short and long term.

The import of heavy metals into various sources of drinking water supply is one of the major problems of water quality, especially in industrial areas. The aim of this study was to investigate the ability of mercury and arsenic metal pollutants to be removed from aqueous solutions using green oxide nanoparticles synthesized by green method. For this purpose, the extract from an indigenous lichen sample of Ardabil province was used as a sorbent for synthesis of iron oxide nanoparticles.

For the preparation of magnetized iron oxide nanoparticles, a fast and common method called co-adsorption was used. In this method, a mixture of bivalent and trivalent iron salts with a specified stoichiometric ratio is added to a certain volume of the extract obtained from Sinensis Ramalina (SR). Due to the use of lichen in the process of synthesis of iron oxide nanoparticles, the method used in the present study is also referred to as the green synthesis method. UV-Vis spectrophotometry, XRD, FT-IR, SEM and EDX elemental analysis were used to confirm the synthesized iron oxide nanoparticles.

In the spectrophotometer spectrum, the peak appearing at 574±5 cm-1 indicates the transfer of oxygen electrons to the iron synthesized from SR lichens. The XRD spectrum also confirms the purity of the iron oxide nanoparticles, as the diffraction pattern was correctly obtained at 2θ=30.40, 35.75, 43.60, 57.90, 63.60. The uniform spherical nature of the iron oxide (III) nanoparticles with a size between 31.74 to 53.91 nm can be seen using SEM images. EDX analysis was also used to show the elemental structure of the synthesized iron oxide nanoparticles. Elemental analysis revealed that the synthesized nanoparticles contained 19.68% by weight of iron and 51.49% by weight of oxygen.

Studies showed that mercury follows the Langmuir adsorption isotherm model (R2=0.998) and arsenic follows the Freundlich adsorption isotherm model (R2=0.968) and the removal process in both metals is spontaneous and exothermic. The data obtained from the kinetic studies of removal of both metals from aqueous solutions were fitted to the pseudo-second-order kinetic model with an appropriate correlation coefficient above 0.99. The ability to remove arsenic and mercury by magnetic iron oxide nanoparticles synthesized by SR plant extract was 71.02% and 72.84% at pH=4 and initial concentration of 50 mg/l, respectively.

So far, due to legal regulations, the general policies of sustainable productivity of water resources have not been implemented.The purpose of this study is to provide policies and programs to control and manage water resources in the short, medium and long term.In this study, we reviewed the scientific reports published in the articles and booksto identify potential challenges in dealing with water policies.According to the topic, the key findings are summarized in 11 general policy.Research shows that major institutions such as the Ministry of Water, the Irrigation Department, the Budget Office, and the National Council for Economic and Social Developmentare needed to approve the draft water policy.The government's long‐term and short‐term water resources management strategy must be formulated.A short‐term strategy is needed to meet the government's goals of developing water resources.The Cabinet is expected to consider the proposed strategies as a national water resources project.

Water resources management is a process that confronts competing and conflicting interests and perspectives. The purpose of this study is to investigate the needs and policies of environmental pollution monitoring and the role of policy in implementing the program. The results show that an integrated approach to water resources management strengthens the mechanism of dialogue, negotiation, and contribution. The use of these principles creates strategies and subsequently induces the planning process. Political commitment must be maintained throughout the planning process, but resistance may occur in case of any major changes. Close consultation and cooperation with affected and interested ministries at the highest level is critical while preparing the plan. Online identification and monitoring of water resources quality as a driver of continuous quality improvement is crucial and achieves a high level of quality assurance in achieving the goals. Therefore, an intelligent computer‐based system is essential for quality management and water resource evaluation processes. Online identification and monitoring can help the quality assessor to evaluate performance effortlessly, automatically, and without delay.
