However, the dynamics of SOC fractions and the underlying microbial mechanisms during vegetation restoration remain poorly understood. This study examined the dynamics of SOC fractions, microbial community structure, and carbon cycle functional genes in the rhizosphere soils of Cryptomeria fortunei (C. fortunei) and Trifolium repens (T. repens), established at zinc smelting slag sites for 4, 6, and 12 years. Results indicated that SOC fractions, including dissolved organic carbon (DOC), microbial biomass carbon (MBC), particle organic carbon (POC), and mineral-associated organic carbon (MAOC), significantly increased with restoration age and were predominantly distributed within micro-aggregates. Bacterial and fungal abundance and diversity were significantly higher in revegetated soils compared to control (CK) soils. Both microbial phospholipid fatty acids (PLFAs) and microbial residue carbon in bulk soils and aggregates significantly increased over time, with bacterial PLFAs exceeding fungal PLFAs, while fungal residue carbon contributed more than bacterial residue carbon to microbial carbon. Total PLFAs were more abundant in 2-0.25 mm aggregates, while total microbial residue carbon was concentrated in <0.25 mm aggregates. In bulk soils, key carbon fixation genes (e.g., korA, gltA, sdhA, mcmA) and degradation genes associated with hemicellulose (e.g., rfbB, xylF, xylH) and starch (e.g., SGA1, malQ) were identified. The abundance of carbon cycling genes initially increased and then decreased in C. fortunei-revegetated soils, whereas a continuous decline was observed in T. repens-revegetated soils. Partial least squares pathway modeling (PLS-PM) revealed that restoration years directly influenced SOC, enzyme activity, and microbial communities, while indirectly affecting carbon cycling genes through changes in microbial communities. Notably, the effects varied between the two plant species.

A 21-month monitoring campaign was conducted, covering pre-dredging (12 months), dredging (4 months), and post-dredging (5 months) phases.

The results revealed significant changes during dredging, including increased pH and oxygen levels, and frequent exceedances of turbidity thresholds set by French regulations. TME concentrations in the water column generally decreased during and after dredging, especially for arsenic (As), nickel (Ni), lead (Pb), and lithium (Li), while organotin levels remained stable. Aluminum (Al) concentrations stayed high throughout, and cadmium (Cd) and copper (Cu) showed temporary reductions that were not sustained post-dredging. In sediments, TME levels decreased, but organotin concentrations rose, particularly in technical zones. This study highlights the need to revise current dredging regulations by expanding monitoring beyond turbidity to include resuspended contaminants and hydrodynamic conditions.

This paper, drawing on the information asymmetry and signaling theories, delves into the impact of divergences in ESG ratings among various institutions on corporate financing constraints. By taking the sample of Chinese A-share listed companies during the period from 2018 to 2022, and using an index of ESG rating divergence, we test the theoretical hypotheses. The empirical results indicate that ESG rating divergence exacerbates financing constraints, which still hold after conducting various robustness tests. From the perspective of analysts, this phenomenon occurs because the divergences in ESG ratings lead to increased prediction biases, thereby intensifying the corporate financing constraints. Nevertheless, compliant ESG disclosure can mitigate the adverse effects of ESG rating divergences on a company's financing constraints. Moreover, within enterprises with higher ESG ratings and greater profitability, the influence of ESG rating divergences on financing constraints is less pronounced. Further analysis shows that the effect of ESG rating divergence mainly stems from domestic rating divergence, domestic and international rating divergence, and environmental rating divergence. Additionally, the impact of the inter-institutional difference, potential for ESG development, and the impact on Alpha have also been analyzed. This study significantly enriches the theoretical framework of ESG rating divergences, provides new empirical evidence on the effects of ESG ratings divergences on corporate financing activities, and offers recommendations for investors to better grasp ESG information, as well as for both enterprises and governments to alleviate financing constraints.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"389 ","pages":"126188"},"PeriodicalIF":8.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144300906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

In general, slightly acidic conditions (pH 5-7) promoted RBBR, RB and STX adsorption; alkaline conditions (pH > 9) promoted IB adsorption. The X-ray photoelectron spectroscopy revealed a complex physical adsorption process involving dispersion forces, hydrogen and electrostatic bonding.
