This narrative review critically synthesizes mechanistic insights into nanobubble (NB) technology, its interactions with soil microbial communities, and their applications in enhancing bioremediation of contaminated and saline soils. NBs (<1 µm improve the gas transfer, generate reactive oxygen species (ROS), and facilitate interfacial interactions that promote microbial growth, metabolic activity, and community resilience. They enhance carbon dioxide fixation, soil porosity, nutrient availability (especially phosphorus), and contaminant bioavailability. When combined with microbial agents or phytoremediation, NBs have achieved up to 26% salinity reduction and 44% yield increases in cotton production under saline conditions. However, most evidence comes from lab/greenhouse studies; field-scale validation, energy costs, potential ROS toxicity at high doses, and long-term ecological impacts remain undetermined key uncertainties.

Accurately identifying ecological compensation areas and establishing scientifically sound compensation standards are critical for alleviating the conflicts between economic development and ecological conservation. This study takes the middle reaches of the Yangtze River urban agglomeration (MYUA) as the study area and focuses on three key ES in 2023-carbon sequestration (CS), air purification (AP), and water purification (WP). Centered on the questions of what to compensate, who should compensate, and how much to compensate, this study conducts a quantitative assessment of ecosystem service supply and demand, a spatial analysis of ecosystem service flows (ESF), and a systematic estimation of ecological compensation standards. The results indicate that: (1) The overall supply-demand matching of ES in the MYUA is relatively good, with the degree of matching ranked as WP > CS > AP; (2) Significant differences exist in the spatial flow characteristics of the three services. The CS forms 16 intercity flow pathways, with transfer distances ranging from 32.51 to 339.40 km. The AP constitutes a flow network composed of 26 pathways, with transfer distances between 22.32 and 445.58 km. The WP exhibits 21 instances of spatial transfer, among which the flow from Changsha to Jingzhou is the largest (640.73 t), while the flow from Xiangtan to Ezhou is the smallest (0.27 t); (3) The total ecological compensation amounts reach 1.411 billion CNY (≈ 0.20 billion USD) for CS, 678 million CNY (≈ 95.50 million USD) for AP, and a relatively lower 7.6002 million CNY (≈ 1.07 million USD) for WP.

Many studies have highlighted their agricultural and environmental benefits, including improving crop yields, reducing nitrate leaching, and lowering nitrous oxide emissions. However, their unintended presence in the environment (e.g., surface water) and the food chain has raised concerns. Individual inhibitors exhibit different levels of risks and benefits that need to be evaluated separately. In this study, a risk-benefit ranking was conducted to prioritize 10 NUIs based on environmental exposure, toxicity, and benefit through the preference ranking organization method for enrichment evaluation. In general, the urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) was identified as the most preferred, with a net flow value (φ) of 0.11 in the risk-benefit ranking of all NUIs, due to its significant agricultural and environmental benefits with low risk from its short half-life. This assessment was supported by the fact that nitrification inhibitors can sometimes increase ammonia emissions, reducing their overall effectiveness in improving nitrogen use efficiency as compared with urease inhibitors. Our results also illustrated that the nitrification inhibitor dicyandiamide (DCD) was a recommended alternative (φ = 0.08) among the evaluated nitrification inhibitors.

The authors proposed that training students on issues of relevance and reliability will lead to improvements in the applicability of academic research for regulatory decision-making while also setting out the importance of cross-sector partnerships in preparing academics for a career in regulatory ecotoxicology. As nearly a decade has passed since the initial workshop, we believe it is important to reevaluate previously identified challenges faced in applying academic research to regulatory decision-making, highlight challenges not previously identified, and assess the uptake of proposed training and skills. A survey was developed and deployed online to gain understanding of the challenges early career researchers (ECRs) face in applying academic research to regulatory decision-making and the training and skills received throughout their career. A total of 52 ECRs responded to the survey. Just over a quarter of respondents (27%) considered themselves to be part of a training network; however, approximately half of all respondents stated that they have received training to understand the regulatory context of their research (52%), ecotoxicology methodologies or guidelines (44%), and principles of quality assurance and good laboratory practice (54%). We explore why ECRs may or may not receive training and assess the extent to which they agree that it has improved the applicability of their research for regulatory decision-making.

The present study proposes a highly efficient reverse osmosis (RO) system for desalinating Persian Gulf water and explores its environmental impacts, energy efficiency, cost-effectiveness, and operational consistency. The designed RO system significantly decreased ionic concentration (90%), total dissolved solids (99.6%), electrical conductivity (99.4%), and NaCl (>95%). The life cycle assessment was conducted by using the production of 1 m3 of potable water via RO desalination of Persian Gulf seawater as the functional unit. The highest environmental burdens appeared to be human carcinogenic toxicity (48%) and freshwater ecotoxicity (19%), mainly from Mg2+, NO3-, and Cl- releases. The RO system adversely affected human health (96.33%) and ecosystems (2.35%) because of effluent and energy consumption, whereas fossil fuels dominated the resource category. Fossil fuels supplied 93.7% of the system's energy requirements, leading to 99.8% of the overall greenhouse gas emissions, specifically CO2 (70.65%) and CH4 (10.8%). Sensitivity analysis revealed that a 20% reduction in Mg2+ and NO3- inputs alleviated impacts by 43.81% to 95.21% across all categories. Furthermore, the Monte Carlo simulation revealed a coefficient of variation <10% for all environmental categories, confirming the credibility and reliability of the results. The water production, capital, and operating expenses were calculated as $0.10/m³, $74,908.2/m³, and $409,687,014.2, respectively. Over a 20-year period, the net present value obtained was $1,984,510,642 with an 11-year payback period. Collectively, implementing an appropriate pretreatment and using renewable energy sources notably reduces the carbon footprint of an RO system (>60%).

With continued growing use of polymers and plastics, there is increased interest in health and environmental assessments of these materials, including chemicals associated with their production and use. Additives and polymer-associated chemistries (APAC), as individual chemicals, are subject to regulation by chemical assessment frameworks (e.g., U.S. Toxic Substances Control Act [TSCA], EU REACH [Registration, Evaluation, Authorisation and Restriction of Chemicals]). Finished products and articles are subject to other regulations (e.g., U.S. Food and Drug Administration Federal Food, Drug, and Cosmetic Act).

Both models are unified because they each use a single set of parameters to characterize the effects of toxicity modifying factors (e.g., pH, dissolved organic carbon [DOC], and major ions) on acute and chronic Zn toxicity. While both models were capable of accurately predicting Zn toxicity, the unified BLM performed marginally better based on quantitative model performance scores and qualitative single-variable pH and DOC evaluations. The unified Zn BLM, which also performed better than the USEPA's hardness equation, was then used to normalize separate acute and chronic species sensitivity distributions to develop acute and chronic 5th percentile hazardous concentrations analogous to the USEPA's aquatic life ambient water quality criteria (WQC).
