The present research uses the comprehensive approach of system dynamics to investigate these policies for reducing CO₂ emissions in Iran’s electricity generation sector. The results show that both policies are effective in improving the country’s energy security, but the impact of the renewable development policy in reducing carbon emissions is more prominent. Furthermore, the results showed that by implementing the photovoltaic development policy, access to the 21% share of this sector of the entire Iranian electricity sector can be realized by the end of 2033.

Four main scenarios based on the number of stories (1, 2, 3, and 4) each including five sub-scenarios based on the size of the rainwater storage tank (2.5m³, 5m³, 7.5m³, 10m³, 12.5m³) and one using solely tap water were defined. Simapro software was used for life cycle assessment which was carried out using the endpoint and midpoint methods. The collected rainwater is assumed to be merely used to fill flush tanks and if it cannot satisfy this demand, tap water will be used. The results show that in an arid city like Tehran, collecting rainwater does not even come close to meeting non-potable water needs, and in most scenarios, tap water must be used for more than half of the days. Despite the low reliability of RWH systems, they perform better than tap water in most environmental impact categories because the processes used to produce tap water have the highest contribution to environmental damage. Among the sub-scenarios that use rainwater for flush tank demands, in almost all environmental impact categories, sub-scenarios that collect more rainwater (higher storage tank sizes) have better performance. The performance of sub-scenarios that use more rainwater is better in the endpoint environmental categories of ecosystems and human health; however, this trend is the opposite in the impact category of resources.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"60 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141943009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to advance the use of magnetic carbon nanocomposites (MCNs) in the sorption of arsenic, studying the influence of feedstock and the presence of carbon coating on magnetic nanoparticles. Previous works have shown that post-pyrolysis treatment improves the stability of MCNs by reducing iron leaching due to the formation of a carbon coating that encapsulates the iron oxide nanoparticles. However, this carbon coating could influence the adsorption properties of MCNs. This investigation deals with arsenic adsorption by four MCNs prepared by co-precipitation of magnetite (Fe₃O₄) nanoparticle into four carbonaceous matrixes, followed by a post-pyrolysis treatment. The pristine carbonaceous matrixes used in the present work were commercial activated carbon (CAC), charcoal (CC), hydrochar from the orange residue (HC_OR), and biochar from sunflower husk (BC_SFH). Pristine carbonaceous materials and MCNs without post-pyrolyzed were also used as arsenic sorbents in water solutions. Additionally, kinetic studies were carried out to explore the sorption properties of different MCNs and pristine materials, concerning the removal efficiencies (expressed as a percentage) and adsorption capacities, determining the equilibrium time. The results demonstrated that the presence of magnetite increases the adsorption of arsenic, being higher in the case of materials obtained by direct co-precipitation than in materials subjected to a post-pyrolysis process.

Kiadaliri","doi":"10.1007/s13762-024-05917-w","DOIUrl":"https://doi.org/10.1007/s13762-024-05917-w","url":null,"abstract":"<p>Nowadays, droughts and the impacts of climate change on water resources and the environment have had significant negative effects. Investigating the effects of climate change on drought indices and streamflow is crucial for water and environmental resource management. Therefore, the present study was conducted in two parts to examine the impact of climate change on drought indices and the amount of watershed streamflow. In the first part of this study, drought modeling was performed using the Standardized Precipitation Index (SPI) and emission scenarios (RCP4.5 and RCP8.5) at three temporal scales (3, 6, and 12 months) during the period of 1995–2055. Then, the climatic impacts on SPI for the period 2030–2055 under different climate scenarios were evaluated. The Karun basin in south west Iran, which is affected by droughts and the impacts of climate change, was selected as the study area. In the second part, the Adaptive Neuro-Fuzzy Inference System (ANFIS) was utilized to estimate watershed streamflow for a 20-year period. Subsequently, in this section, the Whale Optimization Algorithm (WOA) was employed to improve the results of ANFIS. Finally, streamflow prediction for the future period (2035–2055) was carried out using the hybrid model. The results indicated that analyzing precipitation through SPI under different climate scenarios could influence severe fluctuations in droughts within the study area. Frequency analysis of droughts under climate scenarios, RCP4.5 and RCP8.5, demonstrated an upward trend with diverse spatial prevalence patterns. On the other hand, the duration of droughts increased towards the RCP4.5 scenario and remained unchanged according to the RCP8.5 climate scenario. The northeastern, eastern, and southeastern regions will experience the longest and most frequent droughts compared to current conditions. Furthermore, the results of the second part showed that the developed ANFIS-WOA model provides better results (RMSE = 127, MAPE = 98.50, NSE = 0.73) compared to the ANFIS-based model with evaluation criteria of RMSE = 127, MAPE = 98.50, NSE = 0.73. Additionally, in the investigation of the impact of climate change on streamflow using ANFIS-WOA in the time range of 2030 to 2055, the flow rate in most months of the year will decrease by approximately 20 units compared to the baseline period, with a greater intensity of reduction in the RCP8.5 scenario than RCP4.5. However, there will be an increase in streamflow by approximately 20 (m³/s) only in October. The approach used in this study demonstrates the effects of climate change on the level of drought and watershed streamflow, serving as a warning for decision-makers and managers to better manage available water resources. Finally, this approach is recommended for implementation in other similar regions for water resource management and water supply assessment.</p>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"54 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141942910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal approach to overcoming this limitation is the utilisation of salt-tolerant bacteria with the ability to break down petroleum compounds. In this study, the capacity of an artificial halophile consortium comprising native salt-tolerant bacteria with the ability to degrade phenanthrene (<i>Halobacillus</i> sp<i>.</i> strain Q-SH1, <i>Acidovorax</i> sp. strain Q-SH3, <i>Bacillus</i> sp. strain Q-SH12, and <i>Bacillus</i> sp. strain Q<i>-</i>SH14) and natural consortium (isolated from phenanthrene-oil enriched soil) was investigated in the removal of phenanthrene from calcareous saline-sodic soil.
