Sustainable development is a process that envisages a favorable future for human societies. In the sustainable development system, human needs are met by using resources without harming the integrity, beauty and stability of vital systems. The main goal of this study is to simulate the dispersion of suspended particles (PM) and nitrogen oxides (NOX) from the stacks of the joveyn cement factory using the AERMOD8.9 software developed by the Environmental Protection Agency (US EPA). Also, the obtained results were compared with the open air quality standard of Organization of Environmental Protection and the global standard of EPA and also, some solutions were provided to reduce pollutants. The results of the modeling show that the concentration of suspended particles in the 24-hour data of the autumn season is 47.7 µg/m3 and for the summer season it is 31.7  µg/m3, which occurs at a distance of 6370 meters from the emission source. The predicted concentration of suspended particles in each of the summer and autumn seasons in a 24-hour period was lower than the international outdoor air quality standard (EPA) and the Iranian environmental standard; its value was equal to 150 µg/m3. </td> </tr> </tbody> </table> The estimated concentration of the model for NOX in 24-hour data is 92.44  µg/m3 for the summer season and 39.33 µg/m3 for the autumn season and occurs at the distances of 1950 and 2600 meters from the source, respectively. The predicted concentration of NOX in each of the summer and autumn seasons in a 24-hour period was lower than the standards of the international air quality standard (EPA) of 53   µg/m3 and the Iranian environmental standard of 200 µg/m3.

Assistant professor, Department of Forestry, Faculty of natural resources, University of Guilan, Rasht, IranInstructor, Administration of Natural Resources and Watershed Management of Guilan Province, Rasht, IranOne of the approaches to prevent forests’ destruction is to improve the knowledge and participation of local people. In the present study, the role of indigenous knowledge of stakeholders and the participation of local people in the sustainable conservation of the west of Guilan forests were investigated using the theories of normative levels and planned behavior. The statistical population consisted of the residents and native forest dwellers of Sowme'eh Sara, Fuman, and Shaft cities, as well as the experts from General Department of Natural Resources and Watershed Management of Guilan. The sample amount was calculated using the unlimited Cochrane method, and 198 people responded to the questionnaire. The sampling method was simple random and for data analysis, structural equation modeling with SPSS 26 and Smart PLS 3 software were employed. The correlation test showed a significant positive relationship between participation and local knowledge variables with sustainable conservation and these two variables were able to predict sustainable conservation by 0.661 and 0.377, respectively. The structural equation modeling indicated that the experience of forest destruction through the weak participation of local people and indigenous knowledge has an indirect effect on adaptive behavior in sustainable forest conservation. According to the theory of normative levels, the focus of indigenous communities on the promotion of indigenous knowledge as an objective concept along with their focus on abstract concepts such as participation in the conservation of degraded forests can motivate protecting forests. This issue is accordance with the theory of planned behavior which creating a positive attitude among native people in the form of mental norms, lead to the control of behavior based on sustainable conservation. The results of the present research can be used to change the attitude of the general managers of the Natural Resources and Watershed Administration regarding the effectiveness of indigenous knowledge and cultural issues in the sustainable conservation of natural resources.http://journal.eri.acecr.ir/Article/44730Sustainable conservation Adaptive behavior Indigenous knowledge Local people’s participation. perپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602024-129153145articleGeneral Department of Natural Resources and Watershed Management, Mazandaran, Sari, IranMina Nemati Koutenaeem.nemati.k@gmail.com1MSc in Water Engineering - Water Structures, General Directorate of Natural Resources and Watershed Management of Mazandaran, Sari, IranThe aim of the present study is to investigate the most important factors affecting landslides in Behshahr-Galogah coastal watershed. For this purpose, by field survey in the study area, the locations of landslides were recorded with GPS. 7 factors including, distance from the road, distance from the fault, geology, distance from the river, the average of annual rainfall, and land use changes as the most important influencing factors and independent variables were prepared using Geographical Information System (GIS) and entered into the model. For modeling and calculations, the maximum entropy model was used in the Maxent software environment. The results of the Jackknife diagram showed that the three factors of slope, distance from the road and geology have the greatest effect on landslides in the study area. As, by increasing the slope (20-40 percent), landslides increase; also, landslides have an inverse relationship with the distance from the road. For the geological factor, there is the highest probability of landslides within PZq.d and Qra units. The validation of the model using the area under the ROC curve showed that this model is acceptable in the study area with a value of 0.77. On the other hand, the results of landslide risk classification in the studied area showed that 40% of the area has landslide potential. The findings of this study provide an important foundation to assist decision makers in disaster prevention and mitigation and also, it helps to better understand the dangers of landslides which is very useful for the development of risk management measures, so it is suggested to take action in different regions in order to identify high-risk areas.http://journal.eri.acecr.ir/Article/45050Slope Distance from road Jackknife Maximum Entropy Validation perپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602024-129154764articleInvestigating the treatability of prepared food industry wastewater using the chemical process of coagulation and flocculationMitra Gholami Moghadammitra.mgh.55@gmal.com1Fariba Ostovarf_os_46@yahoo.com2Mohadese Tavakolimohadesetavakoli000@gmail.com3MSc in Civil-Environmental Engineering, Higher Education Research Institute of ACECR, Rasht, Iran PhD in Analytical Chemistry, Environmental Research Institute of ACECR (Academic Center for Education, Culture and Research), Rasht, IranResearch expert, Environmental Research Institute of ACECR (Academic Center for Education, Culture and Research), Rasht, IranThis research aims to investigate the treatability of prepared food industry wastewater using the chemical process of coagulation and flocculation.  Ferric chloride (FeCl3) coagulant was used in this process along with polyacrylamide and lime flocculant aids. In order to investigate the mutual effect of the parameters affecting the treatment process, the design of experiments (DOE) software with the central composite model (CCD) was used. Effecting factors on the coagulation and flocculation process such as FeCl3 coagulant concentration in the concentration range of 500-2000 mg/L, initial pH in the range of 5-10, lime and polyelectrolyte with the concentration ranges of 25-100 mg/L and 0.5-2.5 mg/L respectively were evaluated by Jartest device. Chemical oxygen demand (COD) analysis was chosen as the target test to determine the optimal values. Comparison of optimal conditions of single agent and mutual effect of data using experiment design software, an optimal value of pH equal to 7.5, FeCl3 coagulant concentration of 1250 mg/L, and coagulants of lime and polyelectrolyte with concentrations of 60 and 1.5 mg/L respectively, showed COD removal efficiency of 94.15%. Statistical analysis showed that the F-value equal to 19.48 indicates the good agreement of this model with the laboratory results. Also, P-values less than 0.050 indicate the significance of the test. By comparing the laboratory and the predicted results, a good correlation between the results was observed. Finally, the results of this research showed that it is possible to treat the wastewater of the food industry using FeCl3 coagulant, and the treated wastewater meets the standards of discharge to agricultural lands for fields irrigationhttp://journal.eri.acecr.ir/Article/45100Wastewater prepared food industry coagulation and flocculation jar test iron (III) chloride CODperپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602024-129156581articleThe model for evaluating the effectiveness of environmental indicators in green infrastructures in the construction industry with a sustainable development approachSadegh Partanis_partani@ub.ac.ir1Hossein Darvish Roknabadih.darvish.r@gmail.com2Iman Lotfiiman.p.lotfi@gmail.com3Assistant Professor, Department of Civil Engineering, University of Bojnord, Bojnord, IranSenior expert in civil engineering and construction management, The expert in charge of the construction plans office of the Basic Knowledge Research InstituteMSc student, Department of Civil Engineering, University of Bojnord, Bojnord, IranThe purpose of this research is to design a model for evaluating the impact of environmental indicators on green infrastructure in the construction industry with a sustainable development approach.

On the other hand, removing pollutants in these waters is particularly important. Due to the high cost and low efficiency of other pollutant removal methods, biological adsorption methods with low cost have good efficiency for removing pollutants, including cadmium. In this study, cadmium absorption in aqueous solutions was studied using Champia Kotschyana Harvey. Effect of effective variables such as concentration of cadmium ions (0.5-5 mg/L), absorbent value (7-1 gr/L), solution pH (3-8) and contact time (90-90 min) with model response level method became. The design of the Box- Behken was used for experimental data and the best level of independent variables, namely the initial concentration of cadmium ion, pH, contact time and adsorbent value, were selected. Under suitable conditions (pH=4, adsorbent value = 1.5 g/L, contact time = 36.53 min, cadmium initial concentration = 3.3 mg/L) adsorption capacity and cadmium removal percentage, respectively 3/1 mg/ g and 80/14 obtained. Kinetic and isotherm studies showed that the second-order Kinetic model and the isotherm Langmuir well corresponded to cadmium absorption data. According to the results, the Champia K.

Anzali wetland, as one of the largest coastal wetlands in Iran, is known for its global importance in terms of biodiversity. Today, the increase in sedimentation caused by various factors such as deforestation, land use change and river damming has reduced the overall water depth of the wetland, and as a result, its ecological balance and health, biodiversity and sustainability have faced a serious challenge. In this article, the effects of sedimentation and its destructive consequences on the Anzali wetland and the taken watershed management measures have been investigated. This article examines the effects of sedimentation and its destructive consequences on Anzali Wetland, as well as the watershed management measures taken. The results of this study indicate that the watershed of Anzali wetland, particularly the upper watershed, is the main source of sediment load to the wetland. Approximately 80% of the total sediment load comes from the upstream watershed. Overgrazing, deforestation, and limited erosion control measures are among the primary causes of erosion. Overgrazing, deforestation and erosion are the main causes of erosion. Although some efforts have been made to control soil erosion by implementing mechanical, biological, and biomechanical plans in mountainous areas to minimize sediment load from the upper basin, many regions remain not modified due to budget constraints. On the other hand, these plans are facing the challenge of a lack of comprehensive stakeholder participation and community involvement in planning and implementation processes. Implementing comprehensive watershed management approaches that strengthen stakeholder collaboration and consider socio-economic factors not only protects this vital ecosystem but also promotes sustainable development and improves the quality of life for communities that depend on its resources.http://journal.eri.acecr.ir/Article/45998Watershed management Anzali wetland sediments erosionperپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602024-12915115130articleMacrozoobenthos, Biodiversity, Ecology, HormozganKeivan Ejlali Khanghahk_ejlali@yahoo.com1Hamed Kioumarsih_kioumarsi@yahoo.com2ُSaeed Tamadonistamadoni@yahoo.com3Fatemeh Moazzezi famoazzezi@gmail.com4Persian Gulf and Oman Sea Ecology Research Center, Iranian Fisheries Science Research Institute, Agricultural Research Education and Extension Organization (AREEO), Bandar Abbas,Iran P.Box: 7916793165َبخش تحقیقات علوم دامی، مرکز تحقیقات و آموزش کشاورزی و منابع طبیعی استان گیلان، سازمان تحقیقات، آموزش و ترویج کشاورزی، رشت، ایرانPersian Gulf and Oman Sea Ecology Research Center, Iranian Fisheries Science Research Institute, Agricultural Research Education and Extension Organization (AREEO), Bandar Abbas,Iran P.Box: 7916793165Social and Extension Research Department, Guilan Agricultural and Natural Resources Research and Education Center, Agricultural Research, Education and Extension Organization (AREEO), Rasht, Iran This study was conducted to investigate the changes in the biodiversity of macrobenthos communities in 2016, 2018, 2017 and 2018.
