A mesocosm experiment was conducted, exposing sediment-dwelling meiofaunal communities from sediments near Failaka Island (Kuwait) to gradient concentrations of BDE-209 (0.01–20 mg/kg) over a 4-week period. The effect on meiofaunal communities was evaluated by changes in the taxonomic composition, alpha and beta diversity metrics, and the Nematodes/Copepods (Ne/Co) ratio. Our findings reveal that BDE-209 exposure significantly reduced alpha diversity and induced shifts in the community structure, favouring resilient taxa such as nematodes. The increasing Ne/Co ratio underscores structural changes and highlights the pollutant's potential to disrupt sedimentary ecosystem functions. Temporal analyses confirm the persistence of BDE-209 in sediments despite partial degradation, reinforcing its classification as a POP with long-term ecological risks. This study provides valuable insights into the responses of meiofaunal communities to POPs like BDE-209, demonstrating their efficacy as bioindicators for sediment quality. By integrating meiofaunal biomonitoring metrics with mesocosm experiments, this research provides a robust method for assessing the ecological impacts of BDE-209, particularly in regions lacking regulatory frameworks. It also raises awareness of the broader implications of POPs in marine ecosystems. These findings highlight the urgent need for enhanced monitoring programs and stricter regulations to mitigate PBDE contamination in marine ecosystems. Future research should focus on field-based validation of mesocosm results and investigate the interactive effects of BDE-209 with other pollutants to better understand its cumulative ecological impact.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"214 ","pages":"Article 117762"},"PeriodicalIF":5.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143547957","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}

The need to mitigate negative effects has prompted the exploration of removal methods, but neither the success nor the impacts on intertidal mudflats have been assessed. Limited success using a specially-adapted vessel, prompted a shift to manual removal by hand-rake at two UK (Portsmouth and Poole) and two French study sites (Brittany and Normandy). Significant reductions in AM biomass and percentage cover were only observed at one site (Portsmouth), in contrast to significant temporal effects throughout the 180 days at each site. Significant effects of removal on the benthos and birds were also limited to an increase in organic content at Brittany and a reduction in macrofaunal abundance at Poole but with all sites dominated by temporal effects. To assess if AM removal can be used to ameliorate excess nitrogen (N) we calculated the amount of N that could be removed from a site and its potential cost-effectiveness (price of N credit after subtraction of removal costs) within an NTS (Nutrient Trading Scheme). N export by AM removal is influenced by site and season, for example, 66 kg N ha⁻¹ yr⁻¹ (winter) to 95 kg N ha⁻¹ yr⁻¹ (summer) at Poole. N removal rates from some sites (Poole, all seasons; Brittany, autumn) are comparable to other Nature-Based Solutions (NBSs) such as clam aquaculture. However, a single annual AM harvest at these sites yields lower N removal rates compared to seaweed, mussel, and oyster aquaculture. Using a global mean N credit price, the removals at Poole and Portsmouth have medium/high cost-effectiveness across all seasons, potentially generating up to half a million pounds of N credits, which could be increased if post-harvesting value-chains were maximised e.g. biofuel production. Although, implementation at scale could rapidly reduce the many impacts of AMs and contribute to the blue-green bioeconomy revolution, to improve water quality, AM removal must be framed within a multifaceted management process.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"214 ","pages":"Article 117747"},"PeriodicalIF":5.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143547956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive ecological risk assessment framework was constructed based on the importance of ecosystem services, utilizing the risk quotient (RQ) and entropy weighting methods to evaluate the multi-pesticide ecological risks in the study area. Thirteen pesticides were detected in the surface waters, with total concentration levels ranging from 8.18 to 80.60 ng/L, and the herbicide Atrazine and insecticide Imidacloprid were found at the highest levels.

The ecological risk of multi-pesticide pollution was the highest in the coastal regions of Shandong and was associated with Atrazine and Acetamiprid.

This study is the first to systematically explore the growth and reproductive characteristics of <em>U. prolifera</em> sporophytes and gametophytes. The growth rate of gametophytes was significantly higher than that of sporophytes, while sporophytes demonstrated higher spore release capability, showing no significant correlation with temperature. Analysis of 756 floating <em>U. prolifera</em> specimens collected from the Yellow Sea from 2022 to 2024 revealed that the dominant type varied annually: mixed sporophytes and gametophytes in 2022, a predominance of gametophytes in 2023, and sporophytes in 2024. However, the dominant type remained consistent across different survey periods within each year. Given that <em>U. prolifera</em> exhibited a higher probability of in-situ germination in laboratory cultures than in the field, we inferred that floating <em>U. prolifera</em> might employ different reproductive strategies: primarily asexual reproduction in the laboratory and vegetative reproduction in the wild. Through statistical analysis of annual algal types and green tide parameters, we found that the dominant algal type showed a weak correlation with green tide parameters, indicating comparable contributions of sporophytes and gametophytes to green tide formation without significant differences.
