One of the main advantages of the BSC for strategic management is its ability to identify and establish cause-and-effect relationships between the results obtained in each of these perspectives. However, recent studies have highlighted the inherent difficulties in identifying appropriate indicators that can effectively assess dynamic performance, i.e., long-term, especially in sectors such as the Blue Economy (BE), where performance evaluation presents specific and unique challenges.</div><div>This study focuses on validating a Dynamic Balanced Scorecard (DBSC) for the BE, a strategy aimed at fostering the sustainable development of marine and coastal resources. Using BE indicators established by the European Commission, we have designed a DBSC that enables the assessment and monitoring of economic activities in this field. The validation of the DBSC is carried out through the Dynamic Network Data Envelopment Analysis (DNDEA) model, a technique that assesses the relative efficiency of decision-making units in a complex system, allowing for multi-period analysis and considering the interrelationships between indicators. Additionally, Principal Component Analysis (PCA) was employed to simplify complex datasets and highlight the most critical components driving performance across the DBSC perspectives.</div><div>The results demonstrate that the validated DBSC is an effective tool for guiding policies and strategic decisions in the BE. Specifically, the analysis identified distinct areas for improvement across European countries, such as enhancing Internal Processes and Finance while highlighting strengths like Learning and Growth. This framework facilitates targeted interventions and promotes more sustainable practices by providing a multi-dimensional performance assessment. Furthermore, this analytical framework can be adapted and applied in other regions and contexts, contributing to the global advancement of the BE.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"391 ","pages":"Article 126367"},"PeriodicalIF":8.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524105","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}

This column study investigates the long-term implications of using crushed concrete as a filter medium for retention of phosphorus (P), copper (Cu), and zinc (Zn). Results show that crushed concrete achieved significantly higher P retention (98.1 ± 1.6 %) than filter sand and gravel (7.13 ± 9.5 %). Both materials demonstrated high metal removal capabilities (&gt;95 % for Cu and &gt;99 % for Zn). While the filter sand and gravel exhibited leaching of P and Zn during stress tests with demineralised water, the pollutants retained in the crushed concrete column were not prone to remobilisation. A follow-up mini column experiment confirmed that the crushed concrete can sustain its high removal efficiencies for P, Cu, and Zn over extended periods. Freshly crushed concrete with a low degree of carbonation was critical for efficient P removal, whereas grain size was the more influential factor for heavy metal retention. Nevertheless, high P removal coincided with an elevated effluent pH (&gt;11) and pronounced chromium (Cr) leaching in the initial phases of both column experiments. While crushed concrete has strong potential to serve as a long-lasting, sustainable, and cost-effective medium for removal of P, Cu, and Zn from urban runoff, these drawbacks could be a barrier to wider adoption. Therefore, further research should explore optimised sourcing, tailored pretreatment, and application possibilities.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"391 ","pages":"Article 126390"},"PeriodicalIF":8.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524056","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 addition, we consider that competitive advantages can also be dependent on environmental factors, although few studies have tested this. Here, we tested the different mechanisms and their context dependence in a large competition experiment using two aliens and five co-occurring native plants in the presence and absence of an herbivorous snail, under drought and well-watered conditions, and with low and high phosphorus availability. Although intraspecific competition did not significantly differ between the alien and native species, we found that natives had a more negative neighbor effect on other natives than on aliens under well-watered conditions, particularly when there was also phosphorus limitation or herbivory. Similarly, aliens were worse neighbors for natives than for other aliens under well-watered conditions.

The chemical components deposited via rainfall mainly occur in the rainy season, generally summer in China, contributing to the majority of air pollution sink. Here, two rainy seasons-based observation were conducted in a typical summer-frequent-rainfall city in southwestern China, to clarify the variations, controls, and sources of rainwater chemistry. The major ions were SO<sub>4</sub><sup>2−</sup>, NO<sub>3</sub><sup>−</sup>, Ca<sup>2+</sup> and NH<sub>4</sub><sup>+</sup>, with the VWM concentration (in μeq/L) of SO<sub>4</sub><sup>2−</sup> &gt; NO<sub>3</sub><sup>−</sup> &gt; F<sup>−</sup> &gt; Cl<sup>−</sup> for anions in two rainy seasons (2022 and 2023), while Ca<sup>2+</sup> &gt; NH<sub>4</sub><sup>+</sup> &gt; Mg<sup>2+</sup> &gt; Na<sup>+</sup> &gt; K<sup>+</sup> in 2022 and NH<sub>4</sub><sup>+</sup> &gt; Ca<sup>2+</sup> &gt; Mg<sup>2+</sup> &gt; Na<sup>+</sup> &gt; K<sup>+</sup> in 2023 for cations. High rainfall amount in rainy season was the main factor influencing the rainwater ion concentration, while air pollutants also played a non-negligible role. Additionally, some elements (e.g., Ca and Mg) can be accumulated in the atmosphere during the non-rainy days, and the number of dry days thus alters the rainwater ion concentration by the subsequent rainfall. Source apportionment by stoichiometric analysis and positive matrix factorization confirmed that the human-induced sources, including urban waste volatilization and combustion-related emissions, were responsible for 30.3 % of NH<sub>4</sub><sup>+</sup>, 68.6 % of NO<sub>3</sub><sup>−</sup>, and 50.8 % of SO<sub>4</sub><sup>2−</sup> in rainwater.

In sediment covered with mangroves, benthos tended to form more stable networks, potentially contributed by high proportion of negative correlations and ecological services provided by mangroves. In contrast, sediment benthos in anthropogenically disturbed zones might reshape species-interacting patterns and then decrease network stability; they displayed less dispersal ability, which might be related to their narrow niche width and spatial segregation caused by intense mudflat farming. Benthos have migration potential between different zones, and frequent human’ movements will increase this migration. In conclusion, the eDNA method effectively revealed that sediment benthos are sensitive to anthropogenic disturbance by decreasing their network stability and dispersal capability, which may weaken their resilience to environmental changes and increase their spatial heterogeneity even on a small scale.
