Summary: This study investigates the response mechanism of riparian groundwater to pollution sources in the Gusong River, China. Anthropogenic activities and mineral weathering were identified as the main pollution sources. Anthropogenic inputs accounted for 11.4% of riparian groundwater pollution, while river water contributed more. Riparian groundwater acted as a sink for non-point pollutants and removed 13.7% of anthropogenic pollutants from the river water. However, it acted as a source for pollutants from mineral weathering and contributed an additional 19.3% to groundwater.

Summary: This study examined the groundwater quality in Ughelli South, Southern Nigeria, and the factors impacting it. A total of 50 groundwater samples were collected and tested for their physical, chemical, and heavy metal contents. Through various analyses, it was found that most variables fell within recommended limits, except for lead, manganese, and copper which were in the marginal category in a portion of the samples. Lead was identified as the most significant pollutant, and rock weathering was the primary process influencing water chemistry.

Summary: This study investigated river water and groundwater from organic and intensive farming fields in Lithuania and found that the groundwater from organic farms had lower levels of pH, total phosphorus, total nitrogen, NO3-N, NH4-N, and PO4-P compared to groundwater from intensive farming areas, except for one farm. This highlights the importance of groundwater sampling in addition to surface water surveys in water quality studies related to agricultural production.

Summary: Urbanization and coal mining have worsened surface water quality, particularly due to the accumulation of nitrate and sulfate. This study used stable isotopes and hydrochemistry to identify pollution sources and biogeochemical processes in three rivers in northern China. The results showed significant variations in nitrate and sulfate sources among the rivers, with microbial nitrification being the main transformation pathway for nitrate.

Summary: Climate change is causing a decrease in groundwater recharge in some regions while the demand for groundwater for drinking and irrigation purposes is increasing, leading to declining groundwater tables and reduced surface water levels in rivers. This reversal of groundwater-surface water interactions is resulting in drying rivers, impacts on lotic ecosystems, and an increase in contaminants in groundwater. Unpredictability of current models and limited scientific evidence on tipping points for groundwater-surface water interactions have hindered public and political awareness, delaying the implementation of necessary management measures.

Summary: This study investigated the production and characteristics of biochar from African balsam leaves and cow dung. By thermochemical conversion of dried cow dung and African balsam leaves, biochar was obtained in a non-electric reactor. The biochar exhibited a larger surface area and smaller pore size compared to biochar produced from cow dung alone, indicating its potential as a soil additive.

Summary: In this study, engineered biochar was prepared by a one-step chemical activation process in a top-lit updraft biomass reactor. The precursor (orange peel) and chemical activator (zinc chloride salt) were combined in a 1:1 ratio. The FTIR spectra of activated and non-activated samples were similar with few differences, indicating that impregnation with zinc chloride increases the oxygenated functional groups and decreases the carbon content in the biochar. EDS analysis showed increased oxygen content and decreased carbon content in the biochar with zinc chloride activation. SEM spectra revealed rough surfaces with heterogeneous morphology for the biochars. The chemical activation process greatly improved the porosity and surface area of the biochar.

Summary: This study reviews the utilization of biochar and plastics in a composite material known as Biochar-filled plastic composites (BFPCs) and discusses their properties, fabrication techniques, and prospects and challenges associated with their development. BC-filled plastic composites play a significant role in the production of environmentally friendly materials due to their superior mechanical and thermal qualities and low carbon footprint. The properties of BFPCs are influenced by factors such as the type and concentration of plastic, method of fabrication, and BC content.

Summary: In this study, two fillers, calcined cow bone and kaolin, were introduced into a polystyrene resin matrix in varying concentrations through the hand lay-up method. Thermal curing improved the thermal property of the composite, with kaolin having a greater effect than cow bone. The fillers were incorporated into the matrix via chemical reactions, resulting in good interfacial adhesion between the filler(s) and the matrix.

Summary: This study compares the effectiveness of chemical, biological, and physical methods for treating hexavalent chromium (Cr(VI)) waste. The coagulation-flocculation technique, which combines physical and chemical approaches, removes over 98% of Cr(VI) in less than 30 minutes. Most membrane filtering methods can remove up to 90% of Cr(VI). Biological methods involving plants, fungi, and bacteria also successfully eliminate Cr(VI), but scaling up is challenging. Each approach has its advantages and disadvantages, and its applicability depends on the research objectives. These methods are also sustainable and environmentally friendly, limiting their impact on the ecosystem.

Summary: The rapid economic development and population growth in Nigeria have led to significant air pollution emissions, with implications for the environment. This study presents a detailed sectoral emission inventory, identifying transportation, energy, municipal solid waste, wood fuel, and agricultural sectors as the major sources of pollutant emissions. The study also observes an increasing trend in emissions from 1980 to 2020. Additionally, three mitigation scenarios for future emission reductions are analyzed, showing potential reductions through interventions such as liquefied petroleum gas, waste to energy technology, and vehicle inspection and maintenance policies.

Summary: This review paper provides an overview of the production of sawdust biochar through thermochemical processes, including pyrolysis, hydrothermal carbonization, torrefaction, and gasification. The specific yields and performance of these methods vary depending on the feedstock source, process parameters, and equipment used. The properties of biochar, such as carbon content, surface area, and stability, also vary depending on the production method. The study also covers the effects of operating factors on the sawdust-biochar production processes, such as temperature, heating rate, and residence duration. Ongoing research aims to improve biochar properties and applications, making it a valuable tool for climate-smart agriculture and sustainable land management.

A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
