As expected, grain size influenced sediment metal distribution, with fine sediments areas exhibiting higher anthropogenic metal inputs. Due to the impacts of pollution, benthic organisms (n = 1956) showed lower densities near the harbor entrances and metal distribution with high MPI near the harbor entrance (10.4) and marine outfall (5.43), decreasing offshore (2.27–4.25). Metal bioaccumulation significantly differs among benthic organism groups, with mollusks accumulating more due to their trophic position and feeding habits. Lower trophic levels accumulated higher levels of Cu, Cr, Cd, Ni, and Pb, leading to biodilution, while As and Hg biomagnified (TMF &gt; 1, <em>p</em> &lt; 0.05), exceeding safety thresholds and posing ecological and human health risks. PCA exemplified the relationship of sediment available metals with biota, supporting their role as a major driver of bioaccumulation.

The Pearl River Estuary (PRE), the largest estuary in southern China and a core of the high-density Guangdong-Hong Kong-Macau Greater Bay Area, connects the Pearl River to the South China Sea, experiencing complex runoff, intense anthropogenic activities, and sensitive ecosystems. Eutrophication has emerged with rapid regional development. Based on field surveys conducted in the PRE and adjacent waters during summer 2023, this study employed a three-end-member mixing model to analyze the distribution of chlorophyll-a (Chl-<em>a</em>) and nutrients, as well as their regulatory mechanisms controlled by environmental factors. Results showed that high Chl-<em>a</em> zones were concentrated in the salinity transition zone, whose formation was synergistically regulated by factors such as salinity, light availability, and nutrient inputs. Although nutrient concentrations were high within the estuary, Chl-<em>a</em> levels remained relatively low due to light limitation caused by suspended particulate matter. The study area exhibited a nitrogen-rich and phosphorus-limited pattern. Notably, in the estuary and near-mouth regions, where significant changes in Chl-<em>a</em> concentration occurred, a moderate negative correlation (<em>r</em> = −0.456, <em>p</em> &lt; 0.05) was identified between Chl-<em>a</em> and PO₄-P. The three-end-member mixing model confirmed that salinity-driven mixing served as the primary driver of nutrient distribution in the PRE. Model results showed that nutrient processes within the estuary were dominated by additive mechanisms, while consumptive processes prevailed outside the estuary mouth. These findings provide key insights into biogeochemical dynamics and eutrophication management in estuaries.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"220 ","pages":"Article 118479"},"PeriodicalIF":5.3,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678801","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}

This study focuses on determining the presence and levels of legacy contaminants (PCBs, DDT) and trace elements (TEs) in baitfish, a primary prey species of whale sharks in Madagascar, and assessing the potential risks to whale sharks and humans through the consumption of contaminated baitfish (<em>Sardinella gibbosa)</em>.

This research highlights the importance of considering baitfish consumption as a significant pathway for pollutant uptake in whale sharks, suggesting that their exposure may be far higher than previously estimated through zooplankton alone.

However, the interplay between P-limitation and calcium enrichment in shaping its bloom dynamics remains poorly understood. This study investigates the physiological and transcriptomic responses of <em>P. globosa</em> under varying calcium concentrations ([Ca²⁺]) (400, 800 and 1500 mg/L) in both P-replete (36.20 μmol/L) and P-limited (13.75 μmol/L) conditions. Results show that the response of <em>P. globosa</em> to elevated [Ca²⁺] is strongly dependent on phosphorus availability. Under P-limitation, 400–800 mg/L [Ca²⁺] stimulates colony expansion by enhancing Ca²⁺-ATPase activity, maintaining calcium homeostasis, sustaining photosynthesis, promoting glycosaminoglycan (GAG) and exopolysaccharide (EPS) synthesis. These adaptations bolster colony matrix production and increase bloom potential. Conversely, high [Ca²⁺] (1500 mg/L) induced oxidative stress, suppressed polysaccharide production, GAG biosynthesis and impaired colony formation, particularly under P-limitation. Transcriptomic analyses revealed that P-limited cells activated diverse phosphorus-scavenging strategies including phospholipid remodelling, and inorganic pyrophosphate hydrolysis, although these mechanisms were compromised under high [Ca²⁺]. Together these results demonstrate a synergistic effect of P-limitation and calcium enrichment in promoting <em>P. globosa</em> bloom formation. Understanding this calcium‑phosphorus interplay is crucial for anticipating harmful algal bloom (HAB) trajectories in response to increasing nutrient shifts and anthropogenic calcium inputs in coastal systems.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"220 ","pages":"Article 118458"},"PeriodicalIF":5.3,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669934","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}

Using a differential game framework, we analyze the effects of various carbon reduction policies and revenue-sharing mechanisms on waste management performance, carbon mitigation, and blockchain adoption. The results show that under a carbon tax policy, suppliers adopting fixed-price acquisition strategies invest more in blockchain implementation and carbon reduction. When carbon taxes are low, increasing them significantly improves waste management performance and supplier-level emission reductions. Manufacturers' carbon reduction efforts also rise with higher carbon taxes. Blockchain adoption enhances profitability across stakeholders in the system. Among the two carbon policies examined—the carbon tax and the carbon cap—the carbon tax yields the most effective outcomes for marine plastic waste management and emission reduction. However, this environmental improvement does not directly translate into higher profits for all supply chain members. An extension of the model demonstrates that cost-sharing contracts can effectively coordinate dynamic collaboration within the supply chain.
