      The aim of this study was to evaluate the diameter and height growth of two native species of alder (Alnus glutinosa L. Gaertn.) and willow (Salix alba L.) planted in three treatments including natural mulches of straw, wood chips and bare soil without mulch (as control More
      The aim of this study was to evaluate the diameter and height growth of two native species of alder (Alnus glutinosa L. Gaertn.) and willow (Salix alba L.) planted in three treatments including natural mulches of straw, wood chips and bare soil without mulch (as control) treatments. The design of the experiments was in the form of split plots and in the form of completely random blocks located in Chamestan, Mazandaran. The results showed that the regression relationships between diameter and height in alder species were better than those of willow species completely randomly. The study area was in parcels 5 of series 3 district of Surdar -Watashan forestry plan in watershed 49 of forests in the north of the country. The regression coefficient for the independent variable of diameter and dependent variable of height was 0.65 in alder and 0.42 in willow. The results showed that the regression relationship between diameter and height in alder was better than willow species. According to the results of variance analysis, the blocks and treatments did not have a statistically significant difference. The wood chips treatment created the best situation, and after that, the straw treatment and finally the control treatment (bare soil) had a more unfavorable situation than the other treatments. Finally, alder had more favorable conditions for adaptation to the applied bioengineering conditions of the present study vs. willow. Manuscript profile

      In recent years, environmental contamination with plastics has become one of the biggest concerns of various communities. Microplastics (MPs) are plastics less than 5 mm in size. MPs remain in the environment for thousands of years without decomposing. However, accurate analytical methods for the detection and characterization of MPs are scarce. In this descriptive-review study, based on the studies of various researchers and the papers of recent years, this contamination has been introduced and its adverse effects on human health and different environments have been discussed. The results of the studies have shown that microplastic contamination of salt has been reported significantly between four different sources: sea salt 0-1674, lake salt 8-468 and well rock salt 0-204 microplastic per kg (MPs/kg). The number of MPs in untreated water is 1437±34 to 3605±497 particles per liter and in general, the amount of microplastics in treated water is about 83% less than untreated water generally. The length and diameter should be considered when reporting the presence of MPs because the diameter is significant for respiration, while length plays a vital in durability and toxicity. Although the adverse health effects of microplastics have not been fully revealed, but the transfer of chemicals from microplastics to living organisms is a significant concern, and a better understanding of the potential dangers of microplastics is essential to human health.

      Increasing agricultural production due to rapid population growth and consequently increasing water demand in recent decades has led to uncontrolled withdrawal and drop in groundwater levels in Hamadan-Bahar plain. This has led to a sustained drop in groundwater level in the plain and it has caused it to be among the critical plains of the province. This phenomenon has caused water salinity in addition to damage to groundwater resources. The purpose of this study was to investigate the effect of groundwater salinity on potato yield. In order to investigate the effect of water salinity on potato yield, the yield function of this crop has been estimated. By random sampling method, data used from 119 farms were collected in the 2018-19 crop year and the amount of water salinity has been measured in two steps in the laboratory. Based on the criteria and the test, the production function was selected in the form of a quadratic function for estimating the relationships between variables. The results of this study indicate that with an increase of one unit in the amount of water salinity, the production of this product has decreased by 860 kg. The final productivity of water, seeds and chemical fertilizers are 0.2, 23 and -14, respectively, so, it can be said that potato farmers in Hamedan-Bahar plain use optimum amount of water, seed less than optimum amount and chemical fertilizer more than optimum amount.

      The purpose of this study was to identify the status of green library components in the central libraries of the target community, clarify the role of libraries in implementing the culture of a green community and provide solutions and strategies to fill existing gaps and implement a green library. The research method is survey-descriptive. The statistical population includes the libraries of level one universities of the Ministry of Science, Research and Technology and the Ministry of Health, Treatment and Medical Education in terms of space, equipment and manpower. A researcher-made questionnaire was used to collect data. Then the data obtained were analyzed at the level of descriptive statistics with SPSS software and by calculating the mean, standard deviation, absolute frequency and frequency percentage. The research findings showed that the central library of level one university of the Ministry of Science, Research and Technology and the Ministry of Health, Treatment and Medical Education are not in a good condition due to the green components and the standard lead. To have a green academic library, one should start by promoting green thinking and culture in the society, because many of our problems in this field are rooted in culture and misuse of natural and non-renewable resources. The results of the present study can inform libraries about their current situation that how they are far from the ideal situation and use the strategies presented in this study to implement a green library to have a green academic library. We do not necessarily have to start with a green building, these libraries have green missions and they can be known as the green library by implementing several green components in their library.

      In order to condensing the sanitary sludge, two types of complementary centrifugal and screw press devices are usually used. In this paper, in order to increase the efficiency and maximum dewatering in the final stage of the treatment plant, plasma cavitation reactor was used. The input sample of the studied system is the output sludge of the sanitary wastewater treatment plant process of IKCO after entering the digestion tank and staying for one hour. Using a plasma cavitation reactor by rectifier, a voltage of 50 volts and a current of 110 amps was applied to 5 iron electrodes in the cavitation reactor tank with a volume of 1 m3 and the sample was tested for 8 days and every day for 8 hours. Then, the effect of the presence of cavitation reactor on the percentage of dry matter is compared with the centrifuge and multi-disc screw press system when they used alone. Based on industrial and laboratory results, a decrease of more than 80% of wet sludge (conversion of 100 m3 of sludge to about 20 m3 daily) was observed daily. Also, the COD of the outlet water from the final cavitation tank was less than 200 mg/L, also, the amount of its turbidity reached below 50 NTU after passing through sand filters in the final stages which can be used for irrigation and agriculture. Using plasma cavitation reactor was effective in reducing settling time and the final volume of wet sludge. Manuscript profile

      Wastes pollution is the source of many environmental problems. These pollutants cause water, soil and air resources pollution and destruction of natural landscapes and spread of disease, while waste disposal centers pose a threat to rural areas, despite the appropriate distance from urban centers. Determining areas suitable for landfills is one of the general strategies to deal with this crisis. In this research, which has been done by descriptive-analytical method and relying on library resources, after collecting raw layers related to 12 indicators (rural, urban, roads, water resources, floods, land use, pastures, soil, geology, faults, communication roads, etc.) and preparing distance maps and its scaling were investigated using linear software in GIS software of suitable areas for waste disposal in Qasr Shirin city due to its special location in terms of abundant water resources (mineral water and ecotourism). The results show that most of the city of Qasr Shirin is not suitable for waste disposal, these areas are shown in red in the final output of the models. Also, only the parts of the city are suitable for this purpose, which are marked in blue in the final output of the models. Manuscript profile

      Environmental pollution caused by the blood from packaged chicken is one of the biggest problems in the production and distribution of these products. The effect of packaging with cellulose pad and lemon extract on chicken drumstick samples was studied on some chemical, microbial and physical properties. The environmental effects of this study are also important because the compounds released from poultry waste will be reduced if microbial growth is prevented. The results showed that the effect of cellulose and the presence of extracts compared to samples without pad on blood absorption factors, inhibition of TVN increase and peroxide was significant (p <0.01). This can be due to the absorption of compounds in blood by pad and the presence of phenolic and antioxidant compounds in the extract that increase the quality of the samples containing the pad with the extract. The presence of 5% and 1% of lemon extract inhibits the increase of total microbial load and cryophilic bacteria, respectively. Examination of odor, color and total desirability results in chicken thigh samples showed that all samples were in good condition on day 0, which did not change significantly in the smell and color properties after just using the cellulose pad. However, changes in color compared to the smell of the product are more noticeable due to blood absorption and reduction of meat storage capacity over a period of 6 days. In general, over time, the samples containing the extract were in better conditions for all factors than the control samples. As a result, it will prevent the increase of microbial contamination, bloodshed and other harmful factors to the environment. Manuscript profile

      Determining the trophy status is one of the assessment and analysis methods of the ecological balance of wetland ecosystems, because the sustainability and continuity of productivity based on these unique ecosystems requires proper monitoring management and control their environmental conditions because increasing nutrients affect all levels of aquatic ecosystems, including changes in species abundance, migration, reduction of biodiversity, and changes in the structure and composition of communities. Therefore, a suitable method should be used to determine the trophy status, or in other words, the production capacity of an ecosystem. Conventional methods for determining the amount of trophy are based on three physical, chemical and biological parameters. Lorestan province due to its unique construction has unique wetlands, including 11 Poldokhtar wetlands with an area of 142.7 hectares, Bishe Dalan wetland with 913.5 hectares and Tanodar wetland with an area of 1000 hectares. In this study, to evaluate the trophy status, sampling of phosphorus (TP), total nitrogen (TN) concentration or Carlson trophy index (TSI) was used in Poldokhtar, Bishe Dalan and Tanodar for summer and winter of 2019. Based on the annual average of Carlson index, Poldakhtar and Bishe Delan wetlands are in mild mesotrophic trophy conditions and Tanodar wetland is in the eutrophic category. In the wetlands of Lorestan province, the sediment load of suspended solids and water turbidity have been exceeded these wetlands limits and has had destructive effects on the unstable wetlands` body due to the annual entry of large amounts of sediment from the catchment, development of gardens, various recreational withdrawals in Boroujerd and Doroud, increasing the level of river water pollution caused by municipal and industrial wastewater, also, wastes from city and rural recreation centers and wastes from point sources of pollution such as warm water fish breeding ponds.

      Population growth and urban and industrial development processes around the world have made the adoption of alternative energy sources inevitable to reduce fossil fuel consumption as well as their harmful effects on human and environmental health. Over the past decades, the expansion of using nuclear energy as an alternative energy source indicates the widespread production of radioactive waste and the proper management of radioactive waste has become a vital challenge for the international community. The present study is a review study that examines the principles and processes of radioactive waste management and the factors influencing the location of radioactive waste landfills. It also emphasizes on the design of multiple engineering-natural barriers and the adoption of control-monitoring programs with legal requirements for the optimal disposal of radioactive waste to adopt efficient strategies to pay attention to various aspects of sustainability in all aspects of the environmental, social, and economic. The results of the study indicate that the processes of preparation and stabilization of hazardous waste, risk assessment, landfill site selection, the long-term safety of landfills, design of durable structures, adoption of multiple engineering-natural barrier systems, design of monitoring and control programs can reduce humans and environment vulnerability from radioactive waste landfills and can be used as effective frameworks in the radioactive waste management by designers, planners and, engineers.

      Sand filters are composed of sand-filled containers with determined granulation and specified thicknesses of pressurized sand layers that work under pressure and they are placed in the center control system after the cyclone and before the grid or disk filter. The aim of this study was to determine the relationship between water turbidity and Total suspended solids (TSS). To determine the samples turbidity, they were tested using a spectrophotometer and the percentage of light passing was obtained through each sample separately. The test of determining total suspended solids was also performed. The results of this experiment showed that there is a quadratic equation between the percentage of light passing and total suspended solids, which is presented as the main equation from figure 3, that is more correlated with the data. As can be seen, at 450 nm, there is a higher correlation between the turbidity and the light transmittance and less error. Manuscript profile

      The purpose of this research is assessing and planning the urban streets of Arak city. In this research, environmental impacts were assessed by using these three methods: Multi-criteria like rapid matrix, ANP and fuzzy TOPSIS that both of them are decision-making methods. The process that has been followed in this study includes, determining the indicators, (using library studies), specifying geographic area, introducing the options, studying the environmental basic conditions, indicating and predicting and impacts, assessing the impacts using the three mentioned methods and providing the report. In the following, the status of the environmental factors was investigated. Then, the most important factors that might be affected by 58-meter street construction were identified using checklist, and were selected as the criteria for impact assessment. Then environmental impact assessment was separately fulfilled by using three methods like rapid assessment (matrix), fuzzy TOPSIS and ANP. Due to the the more negative impacts relatively to the positive impacts in the rapid matrix method, the project was rejected. In both fuzzy TOPSIS and ANP methods the non-execution option has the most weight and preference. But among these methods, the ANP method is introduced as a suitable method for environment impacts assessment in different projects because of its ability to create a network with interaction between criteria and options at different levels and directions.

      These days, the removal of various dyes from industrial wastewater has become an important concern. Synthetic dyes used in industries such as textiles are complex, toxic and mutant organic materials. Congored is also an acidic dye that is considered a high- risk source of contamination and threatens the lives of humans and other living organisms. Different methods, such as electrochemical, physical and biological processes, are used to remove organic pigment from aqueous samples. Adsorption is one of the most effective modern methods of industrial wastewater treatment, which is a relatively simple and inexpensive process that produces non- toxic and low- risk products. The purpose of this study is removing the Congored dye from aqueous solutions and reviewing the accomplished researches for remove it. Manuscript profile

      Colors are one of the most important pollutants of water, and only one entry into the water can significantly reduce the quality of water. In addition, due to the synthetic origin and the presence of complex molecules in the structure of colors, the purification process is sometimes accompanied by some problems. Colloidal nanoparticles play an important role in technology, especially in the manufacture of glass and ceramics, and are used as a suitable method for cleaning pollutants in water and wastewater. In this study, a chemical regeneration method was used to synthesize colloidal silver nanoparticles. Then, to evaluate the efficiency of synthetic silver nanoparticles, several solutions of dye and pigments such as sulfur, azo, reactive, cationic and anionic dyes were prepared and synthetic material was used for degradation of different colors. Finally, the effect of this colloidal nanoparticle on each of them was studied and compared. The results showed that silver colloidal nanoparticles have the ability to degradation and removal of methyl orange and methyl red dyes from aqueous samples, and these nanoparticles can be used for treatment the water and wastewater containing these dyes.

      Life Cycle Assessment method is an accepted approach for assessing the environmental impacts of a product's life cycle, which is calculated on the basis of two components: the amount of consuming resources and the release of pollutants to the environment. In this study, the environmental impact assessment of pistachio production from the beginning of planting to the field door was estimated using Life Cycle Assessment (LCA) method in Rafsanjan. Initial data were collected through questionnaire method and interview with local farmers. The collected data were analyzed using Ecoinvent®3.0 database and Simapro8.0.4.30 software. The system boundary, field and work unit were considered as a ton of pistachios in this study. The results of this study showed that the use of diesel and electricity as energy sources lead to the release of CO2, NOx, SOx and heavy metals into the environment. Analysis of the pistachio data showed that emissions from fertilizers in the layers had the highest role in source reduction, global warming, toxicity to humans, toxicity to marine aquatics and chemical photooxidation. Emissions from fuel consumption had the greatest effect on ozone layer depletion. Manuscript profile

      New industrial estates developments must follow the effective factors in protection, management and sustainable development of aquifers and water resources in a plain in order to meet the needs of people. Therefore, assessment of the aquifer vulnerability potential for locating new industrial estates settlements is necessary. So, investigation of the vulnerability of Sari plain groundwater resources for locating the industrial zones is necessery. In this research, the risk map of the plain was prepared using a drastic model to assessment of the effective hydrogeological factors in locating the industrial estates of Sari plain. The results of the Drastic model showed that Sari aquifer vulnerability is classified in three groups of highly vulnerable (10.49%,), very highly vulnerable (56.66%) and too highly vulnerable (32.85%). Sensitivity analysis based on two-way single parameter and parameter deletion methods showed that the depth of the water-table factor is the most sensitive factor on the DRASTIC vulnerability index. Sari aquifer is strongly affected by agricultural and industrial activities' pollutants due to shallow water-table; so, the study area is not suitable for establishment of industrial estates based on the final vulnerability map, the aquifer extreme vulnerability potential and the amount of exsisting pollutant. Also, if environmental considerations are not respected by farmers and the existing industrial units in the plain, the aquifer will be suffering serious damages. Manuscript profile

      To investigate the effects of pennyroyal (Mentha pulegium L.) powder on performances, the concentration of some blood parameters and carcass characteristics of broilers, 160 one-day-old Ross chicks were used in the form of a completely randomized design with four treatments and four repetitions. Experimental treatments included the levels of zero (control), 0.2%, 0.4%, and 0.6% of pennyroyal powder. The treatment containing 0.6% of pennyroyal powder compared to the control group had higher feed consumption in the starter period (P <0.05). However, there was no significant difference during the growth period and the whole experimental period. In terms of average daily weight gain and feed conversion ratio, there was no significant difference between the experimental treatments during the starter, growth and the whole experimental periods. The carcass percentage decreased significantly at the age of 42 days in treatments containing pennyroyal powder compared to the control group (P <0.05). There was no significant difference between experimental treatments in terms of weight percentage of carcass components including thigh, chest, abdominal fat, heart, liver, and gizzard. The concentration of triglycerides and plasma VLDL decreased significantly in treatments containing pennyroyal powder and decreased linearly compared to the control group (P <0.05). In terms of cholesterol and plasma HDL levels, a significant decrease was observed in treatment containing 0.4 level and treatment containing 0.2 percent of pennyroyal powder compared to the control group (P <0.05) respectively. Plasma LDL levels were not affected by experimental treatments. The results of the present study showed that the use of limited levels of pennyroyal powder up to 0.6% has no significant effect on the performance of broilers. Manuscript profile

      With increasing industrial activities and discharging untreated wastewater which contains various environmental pollutants to aquatic environments, problems such as reducing the penetration of light, anaerobic conditions and complications such as allergies and cancer for humans and other living organisms will occur. Surface absorption is one of the most effective and efficient methods for the removal of environmental pollutants and among the common methods for treatment of wastewater, applying natural adsorbents are more efficient than the other methods and is more economic. Since there are many natural adsorbents in nature, they are very inexpensive, they are even free in some cases; adsorption of contaminants by these materials can be a suitable way to remove the toxic substances of contaminated water and industrial wastewater. In this paper, we study some of bioactive adsorbents in order to remove contamination from industrial wastewater. Manuscript profile

      Energy consumption is increasing rapidly in the world and it is expected that unrenewable energy sources will expire in the future; therefore, new methods of energy production are becoming more common all over the world. Biogas is one of the new and clean energies, which is produced from anaerobic fermentation of biomass. Guilan province with 238,000 hectares of paddy lands has significant potential for biogas production from organic residues. In this way, this study was carried out to investigate the process of biogas production from the combination of rice straw and animal waste with the ratios of (0-100), (5-95), (10-90), (15-85), (20-80) respectively in three repetitions. The experiment was performed at mesophilic temperature by anaerobic digestion method in the 1/5 lit bottles. An economic and environmental assessment for replacement of biogas produced in this process with fossil fuels was implemented in the village of Pounel in Guilan Province. The results showed that the ratio of 10% of rice straw had the highest biogas production efficiency and by replacing the biogas, 21 percent will save in fossil fuel consumption. It will also prevent the emission of 328.42 kg of CO2 gas into the atmosphere per year. Manuscript profile

      Today, steel production and consumption is applied as an important criterion for measuring the degree of countries industrial development. Needing to investment in construction and economic infrastructure in developing countries, their steel production policy is in the direction of producing the various types of structural steel. In this regard, the main object of the studied steel plant construction is creating jobs in the region, reducing imports and contributing to the country's economic development through carbon ingot production with electric arc furnace technology. After assigning the direct study area of the project, the major contaminants arising from the project implementation were investigated in construction and implementation phases and the corrective actions considered to reduce the contaminants effects. In this research, Rapid Assessment method was used for environmental impact assesment that according to the results, among 96 detected impacts, 55.1 percent of the impacts are negative and 44.9 percent are positive that in case of observing the corrective actions before and after the project implementation, its negative impacts will be minimized. Also, it is recommended that after the plant costruction, apply a periodic monitoring of the outlet contaminants every three months. Manuscript profile

      Water scarcity in arid areas is a serious crisis. The most important step in using rainwater collection systems is to locate suitable areas. In this research, three methods of multivariate regression model and GIS have been used to locate the on-site and off-site rainwater collection method in Tejreh watershed. In this study, canopy, litter, rock and gravel, bare soil, CN, precipitation, slope and soil depth as independent variables and influence on in situ rainwater collection and maximum instantaneous discharge for non-in situ rainwater collection method The title of the dependent variable was considered. The multivariate regression model uses stepwise method, backward removal method, and forward method. And the standard step-by-step method, regression removal method, step-by-step method in collecting rainwater, non-in situ method have been used. The final results by matching the results of previous research show in step rainwater collection, stepwise method and between layers CN, soil, percentage of rock and gravel, and in non-in situ rainwater collection stepwise regression method Standard and among layers the percentage of litter, percentage of canopy, CN, slope, percentage of rocks and pebbles, amount of rainfall, percentage of bare soil and soil depth are known to be important in the equation. Finally, the importance of rain collection sites was divided into four classes: very good, good, medium and poor. Manuscript profile

      The increase of greenhouse gases and the resulting increase in temperature have caused the balance of the earth's climate system and climate changes in most areas of the earth. Therefore, adapting and dealing with climate changes in the water resources sector along with reducing their reflection should be seriously addressed as part of a comprehensive regional response to the vulnerability caused by climate change. In this study, using LARS-WG exponential microscale software and the HadCM3 oceanic atmospheric general circulation model in the form of different scenarios defined in the fourth IPCC report (basic scenarios), including scenario A1, A2, B1, B2, which are more related to regional issues. And the world is concerned from an economic and environmental point of view, the amount of temperature changes and precipitation in the next 100 years of Bashar river basin was predicted. Then the fifth report scenario (RCP) was used and the results were compared with the basic scenarios. The results showed that in both scenarios in the coming period, we will face a large increase in average air temperature, but the decrease in precipitation will not be significant. In the climate change scenario section, RCPs until the end of the 21st century indicate an increase in temperature and a decrease in precipitation in the coming years. The amount of temperature changes in RCP2.6 was estimated between 3 and 13% and in RCP8.5 between 4 and 14%; This increase in temperature on a large scale increases evaporation and prolongs drought periods.
