Adsorbents derived from the bark of Inga edulis were developed for the removal of Cr(VI) ions. Chemical activation with sulfuric acid led to significant changes in the physicochemical properties of the biomass. The adsorbent materials denoted IB (inga biomass) and AIB (activated inga biomass) showed higher removal efficiencies at pH 2.0 and dosages of 1.0 and 0.25 g L−1, respectively. The adsorption kinetics could be fitted using the Elovich model, indicating that the adsorption occurred on heterogeneous surfaces. The maximum adsorption capacities were 46.0 mg g−1 for IB and 356.6 mg g−1 for AIB, with behaviors that could be described by the Langmuir (monolayer) and Freundlich (multilayer) models, respectively. XPS analyses confirmed the reduction of Cr(VI) to Cr(III), due to interactions with oxygenated functional groups. Thermodynamic evaluation indicated that the adsorption was spontaneous, with exothermic character for IB and endothermic character for AIB. Ecotoxicological assays using Daphnia similis showed that a Cr(VI) concentration of 4.34 μg L−1 caused 50.0 % immobility, while adsorption by the materials eliminated the toxicity, demonstrating the effectiveness of the adsorbents in reducing environmental impacts. Additionally, an electrode derived from the adsorption of Cr(VI) on AIB, denoted CPEAIB-Cr-ads-active, presented good performance in the hydrogen evolution reaction (HER), with high current density and low overpotential. The structure of the electrode, with high surface area and the presence of pores and cavities, was favorable for electrochemical catalysis, evidencing its potential for use in applications concerning renewable energy and environmental detoxification. © 2025 Elsevier Ltd

This study aimed to define the dilution, separation of fractions (SF), mass balance, and reuse of the biofertilizer to dilute poultry litter (PL) and to promote water saving while generating an organic fertilizer richer in nutrients. Five dilutions were submitted to mass balance test followed or not by SF and then subjected to the biochemical methane potential (VDI-4630). The highest potential was obtained in the liquid fraction (LF) of the dilution 1:6 (176.1 L CH4 kg−1 VS). This condition was subjected to a semi-continuous feeding, in which the effect of using the biofertilizer to replace water to dilute PL was evaluated. The results showed that the reuse of 40% of biofertilizer had no inhibitory effect on the AD process, reaching 236 L CH4 kg−1 VSadded, allowed 40% saving water and providing a biofertilizer with higher amounts of N. © 2022, The Authors.

The use of rubber septa for controlled release of semiochemicals has raised important discussions about their efficiency and environmental impact since they are composed of fossil raw material. The life cycle assessment (LCA) of the synthesis of a nanocomposite type calcium nanocarbonate/Kraft lignin (NC-CN-KL) obtained from CO₂ capture aimed to quantify the environmental loads involved in the production process. The synthesis evaluated by the LCA was performed on a laboratory scale, since it is a synthetic route classified as technological readiness level 4 (TRL-4) and is in the study and development stage. The LCA was performed according to the principles of the ISO 14044/2006 series of standards, from 101.854 g of nanocomposite as a functional unit. The limitations of the study arose from its synthesis scale, absence of LCA data on the rubber septa and other nanocomposites. The results obtained in the LCA identified electricity and other energy generation processes as the largest contributors to environmental loads for all environmental impact categories studied and suggest that research should focus on these inputs when choosing the sources used in energy nanocomposite formulation processes. LCAs for this synthesis to obtain NC-CN-KL should be carried out on a pilot scale, and it is expected that this work will contribute to the formulation of the material and decision-making, especially regarding the choice of the energy matrix. © 2024 The Authors

The critical minerals industries in Indonesia may pose possible environmental and human health risks due to the release of pollutants into soil, water, and air, as well as the use of materials and energy. This study investigates the possible environmental and human health impacts of Indonesia's nickel, gold, copper, tin, and bauxite mining and processing industries. This study utilizes the latest version of the OpenLCA software, version 2.0, in combination with the Ecoinvent 3.8 database. To evaluate potential environmental consequences and health effects on humans, CML-IA Baseline and environmental Priority Strategies (EPS) are employed in product development. The EPS system was developed utilizing a hierarchical methodology with the objective of furnishing the product developer with data regarding the financial impact of human health impairment resulting from a particular product development. The production of one tonne of gold, nickel, bauxite, tin, and copper results in the emission of 7.34.E+07, 4.61.E+04, 3.10.E+04, 1.02.E+04, 8.01.E+03 kg CO₂ eq/t, respectively, contributing to global warming. This production is associated with asthma cases of 7.79.E+01 (gold industry), 2.21.E−03 (copper industry), 1.81.E−03 (tin industry), 9.21.E−04 (nickel industry), and 4.71.E−06 (bauxite industry) Personyears/t. Electricity consumption and the release of carbon dioxide are the main factors contributing to global warming. The primary cause of asthma cases is the utilization of fuel oil and electricity. Power plant chimneys can employ various technologies, such as cyclones, bag filters, and scrubbers, to mitigate the release of polluting gas emissions. The critical mineral industry must prioritize handling and governing of steam power facilities to minimize their negative effects on the environment and human health. © 2024 The Authors

SCIENTIFIC REPORTS 2023年第1期13卷 1-15页

作者： Supasri, Titaporn Gheewala, Shabbir H. Macatangay, Ronald Chakpor, Anurak Sedpho, Surat Atmospheric Research Unit National Astronomical Research Institute of Thailand Chiang Mai Thailand Energy Engineering Program Faculty of Engineering Chiang Mai University Chiang Mai Thailand Institute of Environmental Science and Meteorology University of the Philippines Diliman Quezon City Philippines The Joint Graduate School of Energy and Environment (JGSEE) King Mongkut’s University of Technology Thonburi Bangkok Thailand Center of Excellence on Energy Technology and Environment Ministry of Higher Education Science Research and Innovation Bangkok Thailand School of Energy and Environment University of Phayao Phayao Thailand

Air pollution in Thailand is regarded as a serious health threat, especially in the northern region. High levels of particulate matter (PM2.5and PM10) are strongly linked to severe health consequences and mortality. This study analyzed the relationship between exposure to ambient concentrations of PM2.5and PM10by using data from the Pollution Control Department of Thailand and the burden of disease due to an increase in the ambient particulate matter concentrations in northern Thailand. This study was conducted using the Life Cycle Assessment methodology considering the human health damage impact category in the ReCiPe 2016 method. The results revealed that the annual average years of life lived with disability from ambient PM2.5in northern Thailand is about 41,372 years, while from PM10it is about 59,064 years per 100,000 population. The number of deaths from lung cancer and cardiopulmonary diseases caused by PM2.5were approximately 0.04% and 0.06% of the population of northern Thailand, respectively. Deaths due to lung cancer and cardiopulmonary diseases caused by PM10, on the other hand, were approximately 0.06% and 0.08%, respectively. The findings expressed the actual severity of the impact of air pollution on human health. It can provide valuable insights for organizations in setting strategies to address air pollution. Organizations can build well-informed strategies and turn them into legal plans by exploiting the study’s findings. This ensures that their efforts to tackle air pollution are successful, in accordance with regulations, and contribute to a healthier, more sustainable future guidelines on appropriate practices of air pollution act/policy linkage with climate change mitigation.

This paper presents an experimental study into the behaviour of concrete filled double skin tubular (CFDST) stub columns. A total of eight axial compression tests were carried out, half of which were filled with conventional concrete and the remainder had recycled aggregate concrete. The columns were circular in cross-section and comprised an austenitic stainless steel outer tube and a carbon steel inner tube, of varying dimensions. Accordingly, hollow ratios of 0.67 and 0.55 were considered. The recycled coarse aggregate was made by crushing test specimens from a previous research project. A replacement ratio of 50% was adopted in these tests. Both the natural coarse aggregates and the recycled aggregates had a maximum diameter of 9.5 mm. During the tests, similar structural behaviour and failure modes were observed between the columns with conventional and recycled aggregate concrete, and the faiure modes were identical. The experimental results are compared with available design procedures and it is ultimately shown that using recycled aggregate concrete rather than regular concrete in CFDST stub columns does not have a significant effect on the performance. © 2021 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

Quantifying the impact of climate change on future air quality is challenging in air quality studies. To investigate to what extent climate change can affect future summertime Ozone (O3) air quality in an urban area, the number of future exceedances of O3 air quality standards associated with regional climate change is projected by developing a statistical approach. An artificial neural network model is employed to simulate hourly O3 concentrations. The model is developed based on hourly observed values of temperature, solar radiation, nitrogen monoxide and nitrogen dioxide which are monitored during summers (June, July and August) of 2009–2012 at an urban air quality station in Tehran, Iran. Climate projections by HadCM3 GCM over the study area, driven by IPCC SRES A1B, A2 and B1 emission scenarios, are downscaled by LARS-WG5 model over the periods of 2015–2039 and 2040–2064. Further calculations are then performed to obtain future hourly temperature and solar radiation values by developing the future diurnal patterns of the variables in the study area. Future hourly O3 concentrations are then projected for five summers in each climate period. The projections are calculated by assuming that current emissions conditions of O3 precursors remain constant in the future. Therefore, only the impact of climate change on future O3 concentrations is investigated in this study. The employed O3 metrics include the number of days exceeding one-hour (1-hr) (120 ppb) and eight-hour (8-hr) (75 ppb) O3 standards and the number of days exceeding 8-hr Air Quality Index (AQI) in the study area. GCM simulations indicate that the surface temperature in the study area increases over all months of the year. The projected increases in solar radiation and decreases in precipitation in future summers along with summertime daily maximum temperature rise of about 1.2 ∘C and 3 ∘C in the first and second climate periods respectively are some indications of more favorable condition for O3 format

Global climate change is considered an irreversible problem, which might directly or indirectly affect all the organisms and ecosystems on the earth and the world has to struggle with. Plants having no effective movement mechanism are the group that global climate change will affect the most. In order to minimize the species and population losses, it is important to estimate the changes in the available distribution areas of species and to ensure the migration mechanism, which the species will need, by the hand of humans. The present study aims to reveal how potential distribution areas of fir, which is among the significant tree species of Turkey and significant portion of global distribution of which is in Turkey, will change from an altitudinal aspect because of the climate change. The results achieved showed that, because of the effects of global climate change, the suitable distribution areas of Abies nordmanniana subsp. nordmanniana will significantly decrease especially at high altitudes and that suitable distribution areas of Abies nordmanniana subsp. equi-trojani will reduce at altitudes higher than 1400 m but increase generally at the altitudes between 200 and 600 m. Moreover, suitable distribution areas of Abies cilicica will shift towards higher altitudes. © 2022, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

The negative effects of climate change have burdened humanity with the necessity of decarbonization by moving to clean and renewable sources of energy generation. While energy demand varies across the sectors, fisheries, including fishing and aquaculture, are among the most energy intensive processes in the food production industry. The synergistic opportunities for co-located aquaculture and renewable energy can thus provide a multifunctional use of space and resources, creating opportunities to meet the identified energy demands of a variety of aquaculture operations. This study has investigated a sustainable energy model for a small-scale shrimp farm in western Taiwan with synergies for the dual use of the water area for solar photovoltaic electricity generation and aquaculture. Based on the simulation results and SWOT analysis, recommendations have been made for the design and operation of a solar-powered aeration system for shrimp farms. The average monthly energy production of 32 MWh is attainable at the estimated canopy space on a carport by installing 896 solar modules on the proposed site, fully covering the power demand of the shrimp farm. These findings have significance for encouraging effective practices in deploying solar techniques in aquaculture and making them replicable in global settings. © 2023 by the authors.
