The coexistence of microplastics and heavy metals in soil can lead to more intricate environmental effects. While plant growth-promoting bacteria have been widely recognized for enhancing the remediation of heavy metal-contaminated soils, little research has been conducted to investigate whether they can alleviate the stress of microplastic-heavy metal composite contamination on plants. We investigated the effects of isolated and screened plant growth-promoting bacteria on the growth and cadmium (Cd) accumulation of under the composite pollution of Cd and polypropylene (PP) with different particle sizes (6.

[Effect of Organic Fertilizer Replacing Nitrogen Fertilizer on Major Grain Yield in China].

Huan Jing Ke Xue

January 2025

School of Civil and Hydraulic Engineering, Ningxia University, Yinchuan 750021, China.

To comprehensively assess the changing pattern of organic fertilizer substitution with nitrogen fertilizer on the yield of major grains in China, with 102 literature as the research object, through Meta-analysis we quantitatively explored the impacts of soil physicochemical properties, climatic conditions, and different nitrogen fertilizer replacement rates and supplemental application amounts. The results showed that the replacement of nitrogen fertilizer by organic fertilizer could increase crop yields compared with those from the application of nitrogen fertilizer alone, and soil quick-acting potassium content, pH, and annual average temperature had the most significant effects on the yields of the three major grains. When the nitrogen fertilizer replacement rate and the amount of supplemental nitrogen fertilizer applied were 31.

To explore the source information and composition characteristics of dissolved organic matter (DOM) in different regions of water bodies in northern cities, considering the urban water system of Shijiazhuang, Hebei Province as an example, ultraviolet-visible spectroscopy (UV-vis) and three-dimensional fluorescence parallel factor analysis (EEM-PARAFAC) were used to explain the optical parameters, abundance, and proportion of different components of DOM in water bodies of different regions. The results showed that: ① The concentrations of NO-N, NO-N, NH-N, TN, TP, and COD in the upstream were significantly lower than those in urban water bodies and downstream (<0.01), and TSI increased after the water entered the city.

The study of terrestrial phosphorus inflow (hereafter referred to as phosphorus inflow) fluxes is essential for controlling non-point source (NPS) pollution. The SWAT model was successfully used to simulate phosphorus inflow fluxes in the Dongting Lake area, while a hybrid model (LSTM and SWAT) was developed and validated for predicting the reduction in phosphorus inflow fluxes among rivers based on three typical reduction scenarios: agricultural control, livestock and poultry reduction, and soil and water conservation measures. The results showed that the inflow flux of TP was 3.

Novel approach to achieving net-zero carbon emissions for development and utilization of coal: Principle, methods, and cost estimation.

Sci Total Environ

December 2024

China Academy of Safety Science and Technology, No. 32 Beiyuan Road, Beijing 100012, China.

China's energy mix is coal-dominated; therefore, it is unrealistic for the country to achieve carbon neutrality through complete decarbonization. As the world's largest carbon emitter, achieving global carbon reduction targets necessitates that China develops low-carbon, clean, safe, and efficient coal development and utilization technologies. This study proposes a new low-carbon coal development and utilization method that integrates in-situ conversion mining and mineral carbonation (ICMMC) to realize coal mining and separation, in-situ backfilling, in-situ conversion, energy storage, and carbon sequestration.

In this research, a sustainable blue-green infrastructure (BGI) was developed to efficiently remove contaminants from stormwater through a combined use of modified porous asphalt (PA) and microalgae cultivation to provide a potential drinking water (DW) source. According to the results, the modified PA with powder activated carbon (PAC) could successfully reduce the level of total suspended solids (TSS), turbidity, polycyclic aromatic hydrocarbons (PAHs), oil and grease to below the DW standards but failed to efficiently remove some heavy metals (HMs) and nutrient pollutants. The results revealed that the treated stormwater was an appropriate medium for microalgae cultivation.

Little is known about the potential impact of point source contamination from seed treatment pesticide residues and degradation products in waste products in treated seed. The presence of these pesticides and their degradation products in the environment has been associated with toxic effects on non-target organisms including bees, aquatic organisms and humans. In this study, we investigated the occurrence of twenty-two pesticide residues and their degradation products in two streams receiving runoff from land-applied wet cake, applied and spilled wastewater originating at a biofuels production facility using pesticide-treated seed as a feedstock.

Botanical Garden, Institute of Nature and Environmental Technology, Kanazawa University, Kakumamachi, Kanazawa, Ishikawa, 920-1192, Japan.

Quaternary ammonium compounds (QACs), ecotoxic organic chemicals linked to multidrug resistance, are being used increasingly, for example to prevent the transmission of infections such as covid-19, in households, hospitals, and industry. To understand the locations, fluctuations, and fractions of QACs entering sewers, we monitored 14 QACs (benzalkonium chloride [BAC]-C8, C10, C12, C14, C16, and C18; dialkyldimethylammonium chloride [DDAC]-C8, C10, and C12; alkyltrimethylammonium chloride [ATAC]-C12, C16, and C18; benzethonium chloride; and cetylpyridinium chloride), and a disinfectant (chlorhexidine) in influent at four Japanese sewage treatment plants (STPs) five times throughout a year. Mass inflows were relatively stable throughout the year, indicating that the recent seasonal covid-19 epidemic did not greatly influence them.

To deepen the understanding of the impact of car-following driving style (CFDS) on traffic conflict risk and address the lack of clear CFDS evaluation metrics, this study proposes an improved CFDS metric based on the Asymmetric Behavior (AB) theory. Interpretable machine learning models were utilized for regression analysis to examine the relationship between CFDS and conflict risk. The generalized AB model calculates the difference between vehicle trajectories and the Newell trajectory, constructing the driving style evaluation metric, which quantifies driver aggressiveness in a manner that is both computationally straightforward and easily interpretable.

A new approach in generating stable crack propagation at twisted bilayer graphene/hBN heterostructures.

iScience

Center for Reproductive Medicine and Obstetrics & Gynecology, Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School, Nanjing, China.

Thermodynamic theory suggests that the obvious mechanical behavior caused by temperature and interlayer angle will affect the physical properties of materials, such as mechanical properties and transportation behavior, and it is different from the behavior in three-dimensional bulk materials. We observe an abnormal physical effect of bilayer graphene/hexagonal boron nitride (G/BN)-carbon nanotube (CNT) heterostructures, with a normalized out-of-plane deformation and normalized bond angle percentage to almost several times higher those of pristine G/BN heterostructures (without CNT) at 700-800 K. Our combined finite element theory and molecular dynamics simulations confirmed that the combination of CNT and interlayer angle diverted and bridged the propagating crack and provided a stable crack propagation path and crack tip opening displacement, resulting in the stress fields to be controlled around the CNT at high temperature.

Both the global and European energy sectors have been undergoing a deep transition for several years, associated with a reduction in the overall share of conventional coal-based energy in favor of new technologies, especially energy from renewable sources (RES). This transition is moving from centralized production towards distributed technologies and from providing only energy to end users towards combining innovative products and services with it. Electricity consumers are becoming prosumers connected to the grid and generating an increasing amount of energy.
