Two of the most critical issues of sustainability are how future ecosystem services (ES) will change under natural and artificial stressors. To answer the above problems accurately with a quantitative manner and develop an intelligent and sustainable management of ecosystems, the projections of ES considering climate change under different Shared Socioeconomic Pathways (SSPs) are needed. However, current ES projection studies often lack quantitative methods to simulate ES dynamics, especially incapability to integrate the interactions between climate and land use changes on ES dynamics. To overcome these challenges, this study proposes a framework for ES simulation under climate and land use change stressors. The framework developed includes four modules: climatic attributes simulation, land use change simulation, scenario design, and ecosystem services simulation modules. Taking China as a case study, this study simulated the evolution of China's ES under the interactions between climate and land use change during the period of 2020–2100. The simulation results show that China's ES increases by 33%, 34%, 9%, and 60% under scenarios SSP1, SSP2, SSP3, and SSP5, respectively. Additionally, the overall growth rate of ES decreases by a gradually slowing rate from the mean at 1% during 2000–2020 to 0.5% during 2020–2100, respectively. Meanwhile, the ES in China shows significantly spatial variability based on simulation results. Shandong province yields the largest potential to be the key area with ES declining in the future. At ecosystem scale, increases in woodland ES are expected to dominate China's ES growth continuously. In the first four decades (2020–2060), development ways under SSP1 scenario are more helpful to promote increase in subtypes of ES, while in the last four decades (2060–2100), ES are expected to increase under SSP5 scenario. The key contributions of this study include tracking the causation and revealing the influencing mechanism of interactions of

There is a major knowledge gap concerning the extent of microplastic pollution in agronomic regions of China, which represent a plastic use hotspot. This study investigated the characteristics of microplastics distributed in agricultural soils from three typical regions (Beijing (BJ), Shandong (SD), and Xinjiang (XJ)) with two plastic film mulching modes (greenhouse (G) and conventional field-based film mulching (M)) in China. The average abundance of microplastics under G and M modes was 3.60×104 items kg-1 and 3.01×104 items kg-1, respectively, and the estimated weight of microplastics per kg of dry soils in BJ, SD, and XJ was 3.12 mg kg-1, 5.63 mg kg-1, and 7.99 mg kg-1, respectively. Microplastics in farmland were mainly of small particle size (50 to 250 μm), with their abundance decreasing with increasing particle size. Among the microplastics detected, polyethylene and polypropylene were the two dominant types present, accounting for 50.0% and 19.7%, respectively. In addition, plastic film mulching mode (G vs. M) had a stronger effect on microplastic distribution than agronomic region. This research provides key data for an assessment of the environmental risk of microplastics and supports the development of guidelines for the sustainable use of agricultural plastic film. © 2023, The Authors.

The role of upflow velocity and Ca2+ concentration in controlling the type and rate of CaCO3 crystallization and their impacts on an expanded granular sludge bed (EGSB) reactor were studied. An improved upflow velocity could promote metastable CaCO3 crystals and achieve the optimized portion of vaterite with a value of 84% at 10 m/h with a small amount of aragonite, thus limiting the scaling in the reactor. The calcium concentration was found similar impacts on CaCO3 crystalline phases. Through stepwise setup of increasing upflow velocity and organic loading rate (OLR), granules cultivated in R3 (Ca2+ 800 mg/L) revealed maximum amount of biomass with biggest particle size distribution and fastest average settling rate, with relative stable COD removal efficiency and the fast optimized reactor capacity at OLR of 16 kgCOD/m3d. A low upflow velocity and a higher Ca2+ concentration could be applied at the initial cultivation stage of the EGSB reactor to promote nucleus formation and granules growth. The Ca2+ concentration had a significant impact on the bacterial community and favoured the growth of Tolumonas and Anaeromousa Anaeroarcus. Archaea, rather than bacteria, was strengthened to contribute more to methane production at a relatively high Ca2+ concentration. © 2023, The Authors. All rights reserved.

Polyethylene microplastics (MPs) derived from plastic mulch films are ubiquitous in agricultural soils. However, the mechanism underlying the effect of MPs on the degradation of polyaromatic hydrocarbons remains unclear. In this study, we investigated the influence of MPs amendment on the profiles of active microbes involved in phenanthrene (PHE) degradation in agricultural soils using DNA-based stable isotope probing (SIP) combined with high-throughput sequencing. Results showed that biodegradation dominated the removal of PHE, and MPs promoted the PHE degradation rate from 79.0 % to 92.3 % in agricultural soils. The addition of MPs could stimulate and prolong the activities of original active microbes responsible for PHE degradation including the genera Flavisolibacter and Nocardioides. Furthermore, the presence of MPs could also recruit novel active microbes, including Gaiella, Methylopila, JGI_0001001-H03, and unclassified Intrasporangiaceae, to participate in PHE degradation. Notably, Flavobacterium, Methylopila, Lysobacter, and unclassified Blastocatellaceae were directly linked with PHE degradation for the first time by SIP. This study provides novel insights into the mechanism underlying the effect of MPs on PHE degradation and enhances our comprehensive understanding of the co-contamination of MPs and PHE in agricultural soils. © 2024 Elsevier B.V.

作者： Liu, Jintao Li, Yongping Huang, Guohe Wang, Shuguang Wang, Panpan China-Canada Center of Energy Environment and Sustainability Research UR-SDU School of Environmental Science and Engineering Shandong University Qingdao266237 China Faculty of Engineering and Applied Science University of Regina ReginaSKS4S 0A2 Canada Shandong Key Laboratory of Water Pollution Control and Resource Reuse School of Environmental Science and Engineering Shandong University Qingdao266237 China State Key Joint Laboratory of Environmental Simulation and Pollution Control School of Environment Beijing Normal University Beijing100875 China

In-depth understanding of the energy-water nexus is necessary to promote the sustainability of energy and water systems. In this study, a multi-perspective factorial-analysis based non-competitive input-output model (MPF-NCIOM) is developed for analyzing energy-water nexus, which integrates non-competitive input-output model and factorial analysis from production-, betweenness-and consumption-based perspectives. MPF-NCIOM can not only provide a comprehensive identification of the key sectors in energy and water systems, but also explore the individual and interactive effects of multiple factors on the energy-water nexus from multi-policy perspectives. A case study of Kazakhstan that is one of the most water-scarce countries in Eurasia and is rich in oil and mineral resources is conducted to prove the applicability of the MPF-NCIOM. Major findings can be summarized: (i) Kazakhstan is a net importer of embodied energy and water under non-competitive imports assumption, where mining is the main exporter and manufacturing is the main importer;(ii) A significant amount of indirect energy and water is consumed in the process of sectoral transactions, accounting for 62% and 37.5% of direct energy and water consumption respectively;(iii) the coupling levels in all sectors are greater than the coordination levels;(iv) MIN, LMA, HMA, EGS and SER are identified as the key sectors affecting energy and water systems through multiple perspectives;(v) The optimal policies that determine whether the focus should be on production- or consumption-side policies for each sector are screened out to promote sustainable development of energy and water systems. These findings are helpful for providing decision support of integrated resource management for energy and water. © 2022, The Authors. All rights reserved.

It has been well-documented that the distribution of ammonia-oxidizing bacteria(AOB) and archaea(AOA) in soils can be affected by heavy metal contamination, whereas information about the impact of heavy metal on these ammonia-oxidizing microorganisms in freshwater sediment is still lacking. The present study explored the change of sediment ammonia-oxidizing microorganisms in a freshwater reservoir after being accidentally contaminated by industrial discharge containing high levels of metals. Bacterial amoA gene was found to be below the quantitative PCR detection and was not successfully amplified by conventional PCR. The number of archaeal amoA gene in reservoir sediments were 9.62 × 10~2–1.35 × 10~7 copies per gram dry sediment. AOA abundance continuously decreased, and AOA richness, diversity and community structure also considerably varied with time. Therefore, heavy metal pollution could have a profound impact on freshwater sediment AOA community. This work could expand our knowledge of the effect of heavy metal contamination on nitrification in natural ecosystems.

Flexible metal-organic frameworks (MOFs) with the gate opening feature can optimize the removal efficiency on the adsorption behavior by accommodating to the specific target molecules. In this study, a flexible MOF denoted as NH2-MIL-53(Al) was investigated to remove Hg(II) from water, in which the adsorption capacities of large-pore NH2-MIL-53(Al) (NH2-MIL-53(Al)-LP) for Hg(II) reached 433.20 mg/g, which is about 4 times higher than narrow-pore NH2-MIL-53(Al) (112.75 mg/g). Further, the kinetic experiment also revealed that nearly 90% Hg(II) can be captured within 60 min for NH2-MIL-53(Al)-LP. Advanced characterizations and density functional theory calculations demonstrated that the strong coordination of the amino and oxygen centers on NH2-MIL-53(Al)-LP to Hg(II). Importantly, molecular dynamic simulation verified the gate opening effect of NH2-MIL-53(Al)-LP, as the faster diffusivity of Hg(II) ions in NH2-MIL-53(Al)-LP was observed. This work provides another opportunity in designing the pore geometry of porous materials for water remediation. © 2023, The Authors. All rights reserved.
