This paper uses inter-provincial data from 2011 to 2021 to examine whether the digital economy will play a positive role in carbon reduction. The findings are as follows: (1) There is a significant negative effect of digital economy development level on carbon emission intensity. (2) In the mediation test section, it is verified that the digital economy can reduce carbon emission intensity by optimizing the industrial structure, promoting the transformation of the energy consumption structure, improving green technology innovation, and optimizing the allocation of resources. (3) The article includes government intervention and human capital as moderating variables, and the results show that Human capital has a positive moderating effect between digital economy and carbon emission intensity, while government intervention has a negative moderating effect. (4) Digital economy has threshold effect on carbon emission intensity. (5) The influence of digital economy on carbon emission intensity shows a heterogeneous relationship between regions and factor endowments. The carbon emission reduction of digital economy in western and northeastern regions is more significant, and the abundance or scarcity of capital, labor and technology factors have different impacts on the carbon emission reduction effect of digital economy. At the same time, it further analyzes the influence of the difference of local government behavior. This paper argues that provinces and cities should strengthen the construction of digital economy, and at the same time should promote the coordinated development of digital economy among regions, which is important to achieve carbon emission reduction.</p>","PeriodicalId":14121,"journal":{"name":"International Journal of Environmental Research","volume":"17 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142181440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of FA content on the hydration and Pb stabilization mechanisms of the FBB was investigated. When a small amount (15%) of FA was added to FBB, hydration product formation and compressive strength were inhibited during early curing (7 d). However, the additional Ca<sup>2+</sup>, SO<sub>4</sub><sup>2−</sup> and OH<sup>−</sup> carried by FA could partially promote the formation of ettringite, so that the compressive strength of 28 d was comparable to that of the treatment without FA addition (32.5 MPa). When a high amount of FA (30%) was added, the hydration process was strongly inhibited throughout the entire curing period, and the leaching concentration of Zn (1052 μg/L) exceeded the limits of the GB/T 30760–2014 standard (1000 μg/L). Pb<sup>2+</sup> was also found to replace Ca<sup>2+</sup> in ettringite to form insoluble Pb-ettringite and Pb<sub>2</sub>(SO<sub>4</sub>)O precipitates, resulting in remarkable Pb stabilisation in system.

This study proposed both renewable and non-renewable energy types to measure energy efficiency and environmental sustainability in China. Furthermore, this study adds technology as an auxiliary factor for energy efficiency and sustainability to resource efficiency. Therefore, the study espouses the N-ARDL technique for asymmetric short and long run positive–negative shocks from 1985 to 2020. The asymmetric outcomes indicate that the positive and negative effects of economic growth and positive technological innovation shocks assist in mitigating carbon secretions, whereas technological innovation is not environmentally efficient during negative shocks. Simultaneously, energy efficiency is measured using both renewable and non-renewable energy factors. The positive shock in coal consumption is alarming for environmental efficiency, whereas its negative shock efficiently mitigates carbon secretions and assists environmental sustainability. However, both positive and negative shocks related to renewable energy are environmentally friendly and support environmental efficiency in China. Therefore, renewable energy is considered an energy-efficient source during asymmetric shocks, whereas non-renewable energy is only efficient during negative shocks, suggesting the sustainable utilization of coal resources. Furthermore, resource rents are inefficient during positive shocks and cause environmental deprivation, whereas they are environmentally efficient during negative shocks.

These NMPs are varied in size (categorised as either microplastics at 5 mm–1 µm or nanoplastics at &lt; 1 µm), shape and chemical composition. They represent a potential threat to aquatic life and human health through ingestion and inhalation. The toxicity of NMPs is attributed to chemical additives introduced during production and the absorbance of inorganic and organic chemical contaminants in environmental settings. This review is designed to discuss the use of biochar as a natural adsorbent for the remediation of water contaminated with NMPs. Biochar is a sustainable, affordable material which can remediate water and contribute to ecosystem restoration. Whilst it is well established as a material to sorb organic and inorganic contaminants, its use to remove NMPs is in its infancy and as such this review sets out to outline the mechanisms and modifications of biochar to remove NMPs from aqueous environments. Although removal mechanisms in laboratory settings are becoming clearer this review highlights that remediative studies need to be undertaken in conjunction with the systematic investigation of the effect of key environmental parameters on remediation and the use of environmentally aged NMPs. The future direction of this discipline also needs to incorporate field trials alongside laboratory work to develop a stronger understanding of the viability of biochar to remove NMPs from waterways.</p>","PeriodicalId":14121,"journal":{"name":"International Journal of Environmental Research","volume":"20 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
