The purpose of this research is to analyze new and different techniques in modern agriculture. In this regard, it has been tried to introduce new methods using super absorbents. With the advancement of science and technology, excellent polymer materials have been developed to retain water. In this article, water retention agents based on natural and synthetic polymers have been reviewed in the last 10 years. Finally, the synthesis of two types of natural and synthetic super absorbents using recycled materials is described. Hydroxyethyl cellulose has excellent characteristics of a superabsorbent such as being biodegradable, non-toxic, high water absorption, and is one of the derivatives of cellulose, which is used in water extraction, wastewater treatment, electrolytic membranes, pharmaceuticals, and pesticides. Alternative soil has many applications in agriculture. And its use can be expanded by combining with different polymers. This combination allows the formation of new biomaterials with improved properties and various applications. As a result of preparing a water retention agent with a practical perspective in agriculture, it not only enhances water absorption and water retention in the soil, but also is resistant to salinity and has mechanical strength, re usability and economic value. is. All these features are present in the introduced super absorbents. Manuscript profile -

Most of the dyes contain complex organic molecules and are harmful to aquatic life and humans due to the presence of metals, aromatics and other compounds in their structure. Removing or reducing the amount of this pollutant entering the environment is essential, and biological absorption is one of these methods. The main purpose of this research is to investigate the removal of blue reactive textile dye by spirulina microalgae. In the process of conducting the research, the effect of variables such as contact time, injected algae dose and wastewater concentration was investigated on the dye removal process and the amount of absorption of the samples was measured by a spectrophotometer and the number of experiments was determined by the design expert software via response surface method (RSM) and the analysis of variance (ANOVA) statistical tool was used to analyze the obtained results. Based on the obtained results, in the optimal conditions of the experiment, the best percentage of dye removal by spirulina microalgae was 100% in contact time of 30 minutes with a dose of 10 ml of injected algae into wastewater with a color concentration of 50 mg/L. Therefore, the use of microalgae, in addition to being an inexpensive and easy-to-operate method for color removal from colored wastewater such as textile wastewater, it will be of interest to researchers as an environmentally friendly method to remove hard degradable pollutants.

Also, the health risk assessment of pesticide residues in apple and grape samples was done using the hazard quotient (HQ) and based on the Monte Carlo simulation for two age groups of adults and children. The results showed that the average residue of ethion in unwashed apple and grape samples was lower than the maximum residue levels of the MRLs of Iran. While, the average residue of Moinphos in unwashed apple and grape samples was higher than the MRLs of Iran. Also, the pesticide residues of Ethion and Moinfos in 100% of the apple and grape samples were higher than the MRL of the European Union. After washing, the average residue of Moinfos and Ethion pesticides decreased by 47 and 45% in apple samples and 44 and 42% in grape samples, respectively. The results of risk assessment based on Monte Carlo simulation showed that the HQ value is less than one with 100% certainty in the age groups of children and adults. Therefore, the consumption of apples and grapes with these two pesticides does not pose any significant risk to the health of consumers. However, due to the use of numerous pesticides, continuous and accurate monitoring and strict regulations regarding the quality and safety of fruits are recommended. Manuscript profile -

Ovan Lake, as one of the beautiful and touristic landscapes in the forbidden hunting area of Eastern Qazvin, has distinct mountain habitats and various species of wildlife. By employing remote sensing techniques for a 30-year period, the process of changes and land use in the hydrological unit leading to Ovan Lake were identified and the trend of their changes was obtained quantitatively in this research. Then, the effect of the related hydromorphological indicators on the area and volume of the lake was investigated. The results showed that, according to the Modified Normalized Difference Water Index (MNDWI), the average area of the lake water zone was 8.15 hectares over the past eight years and based on univariate regressions, its hydrological regime is mainly related to two important factors of precipitation and evaporation. According to the univariate regressions demonstrate a significant relationship between the lake's hydrological regime and precipitation/evaporation rates. The evaporation parameter also showed a logical trend during the statistical years, so that the area and volume of the water zone of the lake has decreased by the increase of evaporation from the free surface of the water. Also, the results of multivariate regression between lake water volume and rainfall and evaporation components showed that the lake volume is more correlated with rainfall. But in contrast, evaporation changes with a greater slope or rate. Manuscript profile -

In this study, 11 grapevine cultivars (Vitis vinifera L.) were exposed to three levels of cadmium (0, 50, and 100 milligrams per kilogram) in a factorial experimental design based on a completely randomized design in the research greenhouse of Malayer University. After applying the different cadmium treatments over a period of approximately 4 months, leaf and rhizosphere soil samples of different grapevine cultivars were collected, and the concentrations of cadmium and zinc were measured using an atomic absorption spectrometer. Significant differences were observed among grapevine cultivars in terms of cadmium and zinc content in leaves and rhizosphere soil. The cultivar "Bidaneh Sefid" had the lowest cadmium content in leaves, while the highest cadmium content in rhizosphere soil was observed in the cultivar "Rish Baba." Moreover, the cultivar "Turkmen 4" had the highest zinc content in leaves, and the cultivar "Rish Baba" had the highest zinc content in rhizosphere soil. Geochemical indices including Igeo, Ipoll, CF, and BAC were evaluated in the surface soil compared to the standard shell and earthworm. Based on the results of this study, in the examination of soil indices in different grapevine cultivars and the impact of different cultivars, according to the Ipoll and Igeo (Müller) indices in the shell, in non-stressed soil without cadmium, it was considered slightly contaminated, and according to the standard shell in the earthworm, it was considered quantitatively contaminated. According to the Igeo index in the shell, in soil under 50 milligrams per kilogram of cadmium stress, it was considered slightly contaminated, and according to the Ipoll index, it was considered slightly to moderately contaminated, and according to the standard shell in the earthworm, it was considered heavily contaminated. According to the Igeo and Ipoll indices in the shell, the results of soil under 100 milligrams per kilogram of cadmium stress, were considered heavily contaminated, and according to the standard shell in the earthworm, it was considered severely contaminated. The results of these indices indicated that zinc was in the non-contaminated category. Manuscript profile -

In this regard, the use of remote sensing has become a common approach due to the provision an extent spatial and temporal information. In this research, in order to land use mapping, first, the accuracy of three common methods of pixel-based (maximum likelihood), machine learning (support vector machine) and object-oriented methods were compared. Then, the spatial and temporal changes of land use in a period of 26 years (1997-2023) assessed using six Landsat satellite imagery. The accuracy of image classification methods was evaluated using Kappa coefficient and overall accuracy indices and the change trend was evaluated using crosstab and spatial evaluation methods. Based on the results, the support vector machine method had the highest kappa coefficient (0.71 to 0.98) and overall accuracy (86 to 99%) for all studied courses. According to the results, poor rangeland had a decreasing trend, and the land uses of very poor rangeland, bare soil, and rainfed agriculture had increasing trends. The area of poor rangeland decreased from 962 hectares (44.36%) in 1997 to 489 hectares (22.57%) in 2023, while very poor rangeland increased from 1138 hectares (52.48%) to 1606 hectares (74.05 percent) in the same period. The results of this research indicated that the trend of land use changes in Jayransoo rangeland is towards the destruction of rangelands and with the passage of time this trend is intensifying. Also, based on the results obtained from this research, it is suggested to use machine learning based classification method to prepare land use mapping in future research. Manuscript profile -

In this experiment, pure nitrogen fertilizer was used at four levels of 0, 60, 120, and 180 kg ha-1and the manure was used at four levels of 0, 6, 12, and 18 tonsha-1. The results showed that the highest plant height, number of seeds per umbrella, and biological yield related to combined treatment were 180 kg of nitrogen with 18 tons of manure per hectare. Maximum number of umbrellas per plant, seed weight per plant, 1000 seed weight, and grain yield were obtained using 120 kg of pure nitrogen with 18 tons of manure, with the highest grain yield of 950.43 kg ha-1and minimum in control treatment was obtained in the amount of 655.4 kg ha-1. Highest percentage of essential oil and essential oil yield with the application of 60 kg of pure nitrogen with 18 tons of manure was obtained 1.946 % and 17.15 kg ha-1 respectively. According to the results, it seems that the application of manure can be an appropriate alternative to reduce the use of nitrogen fertilizer in the cultivation of fennel. The result showed that it is possible to reduce the use of chemical fertilizers by using animal manures and at the same time achieve optimal efficiency and reduce the adverse effects of chemical fertilizers.

These vital and diverse habitats are among life-giving systems that have no alternative. However, none of the world's ecosystems have experienced human-centered injuries and damages as much as wetlands. One of the main threats to Gilan wetlands are human factors such as urban, domestic and industrial wastewater, overfishing and converting wetland marginal lands into agricultural lands. In this study, RGB images were used to assess the water quality parameters of Anzali wetland (Beheshti Island Station) and the related data were compared to the values obtained from the TSS measurement. Based on the obtained data, the intensity of red color (R) in the macroscopic images (with the naked eye) from the wetland can be an environmental indicator to measure TSS concentration. The results of RGB analysis for red color with a correlation coefficient of 0.8513, for green color (G) with a correlation coefficient of 0.832 and for blue color (B) with a correlation coefficient of 0.663 were obtained. Finally, a correlation coefficient (R2=0/8035) between the decrease of RGB values and the increase of TSS concentration was obtained. Other parameters such as pH and Secchi Depth test were also measured in this study. Manuscript profile -

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.

Dyes materials are one of the most important pollutants in industrial wastewater. Today, dyes are widely used in various industries such as textile, paper, leather, printing, and cosmetics. Drainage of colored wastewater does not only affect the aesthetic aspect of the receiving water but also reduces the process of photosynthesis. Also, the colors and their intermediate products are toxic, carcinogenic and mutagenic for aquatic life. Most of these dyes cause skin allergies, dermatitis, and itching, and accelerate the incidence of cancer and mutation in humans. Therefore, industrial wastewaters containing dye need to be treated prior to discharge into the receiving environment. The purpose of this study was to provide a summary of the most important industrial dyes, the health and environmental effects of dyes as pollutants, and to describe the methods for their removal from water and wastewater. In this study, different dye removal methods such as biological, physical and surface adsorption methods were described and the best process for treatment of colored wastewater was introduced considering the economical cost.

This yellow liquid contains a lot of lactose and mineral compounds such as calcium and phosphorus, which is important to achieve in order to use as a food source and prevent environmental pollution. Since the wastewaters of the dairy industry have the highest levels of contamination, if the untreated wastewaters of this industry are discharged, serious environmental problems will be inevitable. On the other hand, a reduction in existing reserves and environmental problems followed by increasing use of fossil fuels has prompted researchers to produce new sources of renewable energy, and it can be said that new biological technologies, such as the use of whey as a way to produce biofuels, reduces the environmental problems of dischrging this kind of wastewaters into nature. Today, using biological technology, these compounds can be used to produce biofuels such as hydrogen, methane, and ethanol. So far, various methods and tests have been performed to produce these fuel sources and in this study, the effective strategies for recycling whey and preventing environmental damages are investigated.

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 -

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
