Coastal environmental issues have become a major concern worldwide. The ecological stability of coastal waters requires the establishment of a scientific and systematic conservation program. This paper explores the relationships between riverine inputs and the nutrient structure of the coastal waters of Dalian. It also analyzes the anthropogenic activities from the watershed on riverine systems, utilizing the data collected in Dalian between 2021 and 2023. The results showed that the Bohai Sea part of Dalian coastal had the highest average DIN in spring at 0.114 mg·L<sup>−1</sup> and highest PO<sub>4</sub>-P in autumn at 0.008 mg·L<sup>−1</sup>, while the Yellow Sea part had the highest average DIN in spring at 0.095 mg·L<sup>−1</sup> and highest PO<sub>4</sub>-P in autumn at 0.005 mg·L<sup>−1</sup> in 2023. In the two sea areas, significant phosphorus limitation was observed, with a notable proportion of over 74 % of monitoring stations recording the DIN/DIP exceeding 16 across the entire coastal water in autumn. The coastal waters of Dalian are heavily influenced by rivers in different seasons. There are higher concentrations of nutrients and more severe phosphorus limitation in estuaries and bays, which respond well to high nitrogen-to-phosphorus ratio nutrient flux inputs from rivers. The nutrient structure of coastal waters is also influenced by physical and biogeochemical processes and current transport. The nutrients from the rivers in the watershed are closely related to anthropogenic activities, and agriculture is an important source. The contribution of nutrient inputs from rivers in different watersheds varies significantly, with the Fuzhou River and Biliu River having the largest input fluxes of TN and TP, amounting to 145.18 and 2.10 t/month and 246.36 and 4.42 t/month in 2023, respectively. It is recommended to adhere to the “land-sea cooperation” and organically integrate the development of watershed nutrient reduction policies with the stabilization of the marine ecosystem.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"218 ","pages":"Article 118193"},"PeriodicalIF":5.3,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 contrast, metagenomic analysis which captures the complete set of genetic material directly extracted from environmental samples circumvents biases inherent to PCR amplification. We hypothesized that metagenomic data could offer superior assessments of benthic environmental impacts associated with salmon aquaculture compared to metabarcoding. To test this, we compared bacterial community structures derived from both metabarcoding and metagenomic analyses of 68 sediment samples obtained from aquaculture installation sites characterized by varying degrees of benthic impact as determined by macroinvertebrate inventories. Bacterial bioindicators were identified from each dataset, and Random Forest models were used to predict the degrees of benthic impacts. Metagenomics identified a greater number of bioindicators at both the family and individual sequence variant levels, resulting in higher predictive accuracy for impact assessments. Notably, only a few bioindicators were common to both methods, suggesting that methodological limitations and distorted abundance patterns in metabarcoding data may lead to spurious indicators.

The origin of plastic pellet pollution is often linked to land-based industrial sites and transportation. However, recent spills resulting from accidents with ships have highlighted the significance of maritime shipping as a source of plastic pellet pollution. In addition, plastic pellets may be released from ships into the ocean as a result of operational leakages during maritime transportation. Although the need to address plastic pellet pollution from ships has been globally recognized, the scale and causal pathways behind this source have not been comprehensively documented and knowledge and data remain fragmented across resources and stakeholders. In order to advance the understanding of the causal pathways of plastic pellet spills and leakages during maritime transportation, this paper applied a transdisciplinary approach using mixed methods. These included expert and stakeholder consultations, systematic review of literature and industry data, and ultimately, the integration of all data in the form of cause-consequence diagrams. Causal pathways of plastic pellet spills and leakages during maritime transportation were found to be of four types of events, namely leaking containers, container damage, container lost overboard and loss of the vessel. Both the causes and consequences of these events were described, as such providing a basis for the identification of a comprehensive set of interventions.
