Increasing aquaculture cultivation produces large quantities of wastewater. If not handled properly, it can have negative impacts on the environment. Constructed wetlands (CWs) are one of the phytoremediation methods that can be applied to treat aquaculture effluent. This research was aimed at determining the performance of Cyperus rotundus in removing COD, BOD, TSS, turbidity, ammonia, nitrate, nitrite, and phosphate from the batch CW system. Treatment was carried out for 30 days with variations in the number of plants (10, 15, and 20) and variations in media height (10, 12, and 14 cm). The result showed that aquaculture effluent contains high levels of organic compounds and nutrients, and C. rotundus can grow and thrive in 100% of aquaculture effluent. Besides that, the use of C. rotundus in CWs with the effect of numbers of plants and media height showed performance of COD, BOD, TSS, turbidity, ammonia, nitrate, nitrite, and phosphate with 70, 79, 90, 96, 64, 82, 92, and 48% of removal efficacy, respectively. There was no negative impact observed on C. rotundus growth after exposure to aquaculture effluent, as indicated by the increase in wet weight, dry weight, and growth rate when compared to the control. Thus, adding aquaculture effluent to CWs planted with C. rotundus supports the growth and development of plants while also performing phytoremediation. © 2024 Elsevier Ltd

Jagakarsa is an urban area in South Jakarta, Indonesia, that uses groundwater for raw water because there are no clean water supply facilities. The significant increase in the need for clean water due to increasing urbanization threatens groundwater availability to maintain the balance of the surrounding environment. Natural conditions with a deep layer of clay and a dense built environment further increase runoff capacity because water has difficulty seeping into the soil. The intense extraction of groundwater without balancing groundwater recharge results in land subsidence. Until now, there has been no research on this issue. Thus, our research is necessary. This research aims to assess the potential of groundwater infiltration areas in Jagakarsa. Due to limited data, as a first step, we used a qualitative model with MCDM analysis (AHP and MIF methods) integrated with GIS to map potential groundwater recharge areas. The AHP method is explained in detail with a matrix system formula, readers can understand the calculation steps more easily. This study uses five influencing factors: geological formation, land use, slope, rainfall, and soil type. The results show that most study locations have low potential (AHP 74.49 % and MIF 75.25 %) for groundwater recharge. This groundwater recharge potential map was validated using groundwater level measurements. The accuracy of the AHP is 74.51 %, and the MIF method reaches 75.26 %. Therefore, further research is needed to obtain appropriate and effective technology for maintaining groundwater availability. © 2024 The Authors

Mechanical oil recovery (i.e., booming and skimming) is the most common tool for oil spill response. Under this procedure the recovered fluid generated from skimming processes during oil spill response may contain a considerable proportion of water (10% ~ 70%). As a result of regulatory requirements prohibiting the discharge of contaminated waters at sea, oil-water mixtures onboard vessels and/or storage barges must make frequent trips to shore for waste disposal. This practice can be time- consuming and/or require a lot of resources and thus reduces the overall efficiency and capacity of oil recovery. One potential solution is on-site oil-water separation and disposal of the decanted water fraction at sea. However, currently available decanting process may have limited oil/water separation capabilities, especially in the presence of oil-water emulsion, which commonly occurs in the skimming process, and may not achieve the standards required by regulatory agencies to address potential concerns over ecotoxicity impacts. This paper comprehensively reviews the principles of and progress in oil/water separation, demulsification, and on-site treatment technologies, and investigates their applicability for decanting at sea to enhance response effectiveness and consequently reducing the environmental impacts of oil spills. © 2022, The Authors.

This study aimed to investigate the sources and characteristics of super-coarse carbonaceous aerosol particles containing chloride in a tropical savanna climate. Aerosol samples were collected from an agro-forest site in Thailand during the dry season and analyzed using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and Fourier-transform infrared (FTIR) spectroscopy. By analyzing the morphology and elemental compositions of individual aerosol particles and applying positive matrix factorization (PMF) analysis, their potential sources have been elucidated. The findings revealed two possible sources of the aerosol particles: mixed biomass burning smoke particles with inorganic salts (probably from saline soil, and sea salt), and halophilic fungal spores. Functional group analysis using FTIR spectroscopy indicated the presence of compounds associated with biomass burning smoke particles and clay minerals, influenced by prevailing NE and SE winds, respectively. Recommendations for further research include continued monitoring, correlation analysis with meteorological parameters, and utilization of transmission electron microscopy (TEM) techniques for detailed visualization and confirmation of aerosol sources. © 2024, The Authors.

Background: Arsenic exposure can cause adverse health effects. The effects of long-term low-to-moderate exposure and methylations remain unclear. Objective: This study aims to examine the association between low-to-moderate arsenic exposure and urothelial tract cancers while considering the effects of methylation capacity. Methods: In this study, 5,811 participants were recruited from an arseniasis area in Taiwan for inorganic arsenic metabolite analysis. This follow-up study was conducted between August 1995 and December 2017. We identified 85 urothelial tract cancers in these participants, including 49 bladder and 36 upper urothelial tract cancer cases. A Cox proportional hazards model was employed. Results: The analyses revealed a significant association between concentrations of inorganic arsenic in water > 100 ug/L and bladder cancer occurrence, with a hazard ratio (HR) of 4.88 (95% CI 1.35–17.61). A monotonic trend was observed between concentrations of inorganic arsenic in water (from 0 to > 100 ug/L) and the incidence of urothelial tract cancer, including bladder cancer (p < 0.05) and upper urothelial tract cancers (p < 0.05). Participants with a lower primary methylation index or higher secondary methylation index had a prominent effect. Conclusions: Rigorous regulations and active interventions should be considered for populations with susceptible characteristics. © 2023, The Author(s).

Development of Ag/Ti3+/Tio2-Coated Ceramic Water Filter for Removing Bacteria and Organic Pollutants

SSRN

引用

SSRN 2024年

作者： Huang, Jing Huang, Guohe Yin, Jianan Yao, Yao Zhang, Peng Li, Mengna Feng, Renfei Chen, Ning Environmental Systems Engineering Program University of Regina ReginaSKS4S 0A2 Canada Sustainable Functional Biomaterials Laboratory Department of Wood Science The University of British Columbia VancouverV6T 1Z4 Canada Canadian Light Source Inc. 44 Innovation Blvd SaskatoonSKS7N 2V3 Canada

In this study, we developed an Ag/Ti3+/TiO2-coated ceramic water filter (ATTCF) designed for emergency drinking water treatment. The filter was fabricated using Ag/Ti3+/TiO2 nanocomposites (ATTs) synthesized by reducing Ti4+ and Ag+ with NaBH4 and L-ascorbic acid, respectively. The ATTs exhibited high efficiency, removing over 90% of carbamazepine (CBZ) within 10 minutes under both dark and light conditions, mainly through the reactive oxygen species •OH and •O2−. ATTs were embedded in sodium alginate and cross-linked with Ca2+ to strengthen their adhesion to the ceramic water filter (CWF). Polypyrrole was grown in situ on the surface of the CWF to facilitate the successful loading of ATTs. Due to the interaction between calcium alginate and polypyrrole, ATTs were firmly attached to the CWF, forming ATTCF. The developed ATTCF can remove more than 80% of CBZ during filtration and maintain satisfactory removal efficiency after regeneration. The effects of environmental conditions on CBZ removal performance were also investigated. While environmental pH and certain co-existing ions had minimal impact on the catalytic activity of ATTs, some co-existing ions significantly affected the CBZ removal performance of ATTCF. It was inferred that both ATTs and polypyrrole played important roles in CBZ removal by ATTCF. Additionally, the antibacterial activity of the ceramic filter was enhanced after coating with ATTs. Overall, the developed ATTCF shows potential for various emergency applications, addressing pollution concerns and providing safe drinking water. © 2024, The Authors. All rights reserved.

We review future global demand for electricity and major technologies positioned to supply it with minimal greenhouse gas (GHG) emissions: renewables (wind, solar, water, geothermal, and biomass), nuclear fission, and fossil power with CO2 capture and sequestration. We discuss two breakthrough technologies (space solar power and nuclear fusion) as exciting but uncertain additional options for low-net GHG emissions (i.e., low-carbon) electricity generation. In addition, we discuss grid integration technologies (monitoring and forecasting of transmission and distribution systems, demand-side load management, energy storage, and load balancing with low-carbon fuel substitutes). For each topic, recent historical trends and future prospects are reviewed, along with technical challenges, costs, and other issues as appropriate. Although no technology represents an ideal solution, their strengths can be enhanced by deployment in combination, along with grid integration that forms a critical set of enabling technologies to assure a reliable and robust future low-carbon electricity system.
