The impacts of El Niño-Southern Oscillation (ENSO) on salinity and alkalinity in an equatorial coral reef lagoon (Kanton) are investigated using water samples collected in three non-El Niño years (1973, 2012, and 2018) and one El Niño year (2015). A one-dimensional, advective-diffusive model is developed to aid in the interpretation of the sparse observations and make estimates of net ecosystem calcification (NEC) rates. The Kanton lagoon experiences extreme salinity and alkalinity variations driven by ENSO variations in precipitation. During the non-El Niño years, salinity increases from the ocean (35.5 psu) to the back of the lagoon (38 psu) because evaporation exceeds precipitation, and water resides in the back of the lagoon for ∼180 days. Early in the 2015–2016 El Niño, the back of the lagoon is only ∼1 psu saltier than the ocean because precipitation had begun to exceed evaporation. The model suggests that during El Niño events, when precipitation substantially exceeds evaporation, the back of the lagoon is less salty than the ocean (30–32 psu). Alkalinity variations in the lagoon are primarily due to dilution or concentration driven by the ENSO variations in precipitation and NEC that causes an alkalinity deficit of ∼250 μmol/kg in the back of the lagoon. The estimated NEC rate in 2015 is ∼25% lower (4.1 mmol/day) than in the non-El Niño years (5.3–5. 7 mmol/day). The NEC rates and coral cover measurements indicate that the Kanton lagoon has recovered from the complete loss of coral cover during the 2002–2003 El Niño. Rainfall variations cause the Kanton lagoon to be much saltier than the ocean between El Niño events and probably much fresher during El Niño events Large variations in alkalinity in the Kanton lagoon are due to dilution driven by precipitation and ecosystem calcification Calcification rate estimates suggest the Kanton lagoon has recovered from a complete loss of coral during the 2002–2003 El Niño This study examines the impact of large variatio

The demand for clean water is increasing due to the increasing population, water pollution, economic development, and climate change. The surfacing of emerging pollutants has put tremendous pressure on the freshwater supply chain. Furthermore, the ineffectiveness of conventional treatment plants in removing these pollutants and adhering to the stringent water quality standards have also increased the troubles in providing safe and clean water to the masses. Thus, advanced water and wastewater treatment technologies are required for fulfilling the growing water demand. Nanomaterials enabled advanced water, and wastewater treatment technologies have shown the potential to deliver clean water. They can also be used to augment water supply by utilizing non-conventional water sources like brackish water and wastewater. Graphene, the wonder material due to its unrivaled physicochemical, electrical, mechanical properties, and functionalization possibilities. Recently, a facile reagent-free method for graphene production was reported using a CO2 laser, termed laser-induced graphene (LIG). Soon after the discovery of this single-step, solvent-free LIG preparation protocol, a plethora of studies have been done across the globe in various fields including, electronics, energy storage, sensors, and water treatment. Here, we have summarized the important LIG studies done in the area of water treatment, which talked about LIG fabrication advancement on a wide variety of carbon substrates for LIG-based filters, membranes, electrodes, and composites for anti-biofouling, antibacterial, pollutant removal, solar thermal distillation, and sensing purposes.

With the increasing trend of population concentration and more frequent disaster events in cities, understanding the dynamics of urban inequalities of cities has become crucial for enabling faster and more efficient citizen responses with reduced risks. However, existing models often fail to effectively capture the complex and multifaceted nature of urban inequalities due to their inability to represent the weights and dynamic changes of the evaluation framework. To address this limitation, we propose a novel adaptive framework based on Bidirectional Encoder Representations from Transformers (BERT) that leverages a literature-driven meta-analysis to comprehensively assess the spatial dynamics of the Urban Inequality Index (UII). The framework involves a structured three-step process. First, we gather and screen 35, 819 in total scholarly literature within defined temporal scopes to acquire UII related to economic, educational, infrastructural, environmental, social, and health dimensions to ensure a broad and diverse dataset. Second, we employ BERT and a weights calculation algorithm to identify and weigh potential indicators, providing a contextualized understanding that surpasses conventional analytic techniques. Finally, we amalgamate and process data from assorted sources to formulate a panel dataset, facilitating the computation of the UII, followed by spatial analysis and visualization to expose underlying patterns and trends. We applied this framework to reveal significant spatial dynamics and trends in UII for the periods 2000–2010 and 2010–2020, using Shanghai as a case study. Our findings emphasize the increasing importance of environmental indicators in UII evaluation, reflecting broader global trends toward sustainability and resilience. These results underscore the need for continuous monitoring and adaptive policies to mitigate urban inequality and promote more equitable urban development effectively and also highlight the evolution of the urban inequa

80% of the use of clean water by the community becomes wastewater which must be managed first before being discharged into surface water bodies not to cause disturbances to the water body environment, public health, and environmental aesthetics. This study examines the effectiveness of seven reactors for domestic wastewater treatment in reducing levels of Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). These reactors are the Moving Bed Biofilter Reactor (MBBR) with kaldness media, only MBBR, filtration pipes, the addition of papaya seed bio coagulant, Up-flow Anaerobic Sludge Blanket (UASB), pipes filled with soil, and a combination of filtration and Anaerobic Baffled Reactor (ABR). This research was conducted with a descriptive method of literature review. The results showed that the reactors, respectively, reduced BOD levels by 83.3%; 78.9%; 15.75%; 93%; 36.9%; 76%; and 79%. They were able to reduce COD levels by 84.2%; 80.58%; 16.79%; 93%; 67.8%; 58%; and 68%. The addition of papaya seed bio coagulant is the most effective reactor to reduce BOD and COD because it contains tannin compounds that have effective clotting ability.

For regulatory purposes, air pollution has been reduced to management of air quality control regions (AQCR), by inventorying pollution sources and identifying the receptors significantly affected. However, beyond being source-dependent, particulate matter can be physically and chemically altered by factors and elements of climate during transport, as they act as local environmental constraints, indirectly modulating the adverse effects of particles on the environment and human health. This case study, at an industrial site in a Brazilian coastal city – Joinville, combines different methodologies to integrate atmospheric dynamics in a strategic risk assessment approach whereby the influence of different wind regimes on environmental and health risks of exposure to PM2.5-bound components, are analysed. Although Joinville AQCR has been prone to stagnation/recirculation events, distinctly different horizontal wind circulation patterns indicate two airsheds within the region. The two sampling sites mirrored these two conditions and as a result we report different PM2.5 mass concentrations, chemical profiles, geo-accumulation, and ecological and human health risks. In addition, feedback mechanisms between the airsheds seem to aggravate the air quality and its effects even under good ventilation conditions. Recognizably, the risks associated with Co, Pb, Ni, Mn, and Zn loadings were extremely high for the environment as well as being the main contributors to elevated non-carcinogenic risks. Meanwhile, higher carcinogenic risks occurred during stagnation/recirculation conditions, with Cr as the major threat. These results highlight the importance of integrating local airshed characteristics into the risk assessment of PM2.5-bound components since they can aggravate air pollution leading to different risks at a granular scale. This new approach to risk assessment can be employed in any city's longer-term development plan since it provides public authorities with a strategic

Effects of refining degree, HwBKP-SwBKP mixing ratio, and the type and the dosage of strength agents on initial wet - web strength were investigated. Two types of strength agents consisting of PAE (polyamideamine-epichlorohydrin)-PVA (polyvinyl alcohol), and PAE-MP (micropolymer) were applied. It was found that the addition of PAE-PVA or PAE-MP strength agents can improve the initial wet-web strength of HwBKP-SwBKP sheets by increasing the interaction between pulp fibers and by improving dewatering efficiency and then the solids content of the wet-web. The PAE-MP strength agent showed superior dewatering efficiency than the PAE-PVA strength agent, resulting in a higher solids content and a higher initial wet-web strength at a given polymer dosage. However, the PAE-PVA strength agent showed higher initial wet-web strength at a given solids content than the PAE-MP strength agent. In addition, increasing the refining degree and increasing the amount of longer fibers in stock resulted in the improved initial wet-web strength of HwBKP-SwBKP sheets. © 2020 Korean Technical Assoc. of the Pulp and Paper Industry.
