Ingestion of microplastics by the commercially important Asian green mussel, Perna viridis (Linnaeus, 1758), from a natural mussel bed situated in the northern part of Kerala (southwest coast of India) and the results of experimental ingestion studies using polystyrene microparticles are discussed. Mussel samples from the inter-tidal zones were severely contaminated by microplastics, mainly constituted by fibre/filament, thin films and beads. Polypropylene was identified as the predominant particle type by Fourier transform infrared (FT-IR) spectroscopy. To confirm the ingestion and to track the fate of microplastics in the digestive tract, organisms were fed with orange fluorescent polystyrene beads of 10 μm size along with algal feed at two different experimental concentrations. Short term impacts of exposure in controlled conditions led to abnormal feeding behavior in mussels. Substantial reduction in algal clearance rate and presence of microplastics in faeces and pseudofaeces confirmed the ingestion. Absence of significant differences in microplastic count in soft tissues post depuration implies possible retention of smaller sized particles. Therefore, ingestion experiments involving environmentally relevant concentrations followed by depuration trials, across a range of mariculture species using particles of various types and dimensions may be necessary to establish safety standards for microplastic contamination in seafood.</p>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"220 ","pages":"118468"},"PeriodicalIF":4.9,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144707975","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}

Here we assessed genetic diversity and abundance of bacterial alkaline phosphatases phoD and phosphate transporter phoD and explored how AP activity interacting with them along the salinity gradient of Pearl River Estuary (PRE), which was under heavy anthropogenic pressures. Partial least squares path modeling (PLS-PM) revealed the pathway from environmental variables (pH and salinity) to phoD-harboring bacterial taxa in particle-attached fraction and then to phoD gene copies was the determinant process for AP activity; while AP activity in free-living fraction was mainly controlled by the pathway from dissolved inorganic phosphorus (DIP) to phoD encoding community structure and its gene abundance. Our study highlighted the importance of diverse phoD phosphorus mineralizers, such as some members from Actinobacteria (Actinomadura), Alphaproteobacteria (unclassified Rhodobacteraceae, Roseovarius, Mesorhizobium) and Betaproteobacteria (Ralstonia), while pstS-harboring community was composed of picocyanobacteria. In the outer estuary with the lowest DIP concentration, AP level was activated substantially herein, which corresponded well with the spatial distribution of phoD and pstS gene abundance. High number of phosphatase and transporter genes potentially implied effective hydrolyzation rate of DOP to supplement inorganic phosphorus in the estuary. Researches on the characterization and transformation of DOP are insufficient owing to their complex composition and extraction difficulty. In the recent study, we applied Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) to present a preliminary feature of DOP molecular composition in the PRE. The phosphoesters represented more than 95 % of total DOP, and CHOP compounds (mainly lipids) was a potential substrate for bacterial AP.

Overall, Chl a, SPP and IPP all decreased with increasing distance from the shore. UVB inhibited both SPP and IPP throughout the year, with the inhibition ratios (IR) ranging from 32.01 % to 38.88 %.

To address this knowledge gap, this study presented a comprehensive reassessment of carbon budgets along the Yangtze River Estuary continuum. Based on the radium-derived SGD measurements, dissolved carbon through SGD was significantly lower than carbon burial within small-scale tidal creek systems, but its contribution escalated to 1.5 times carbon burial when expanding to the entire saltmarsh wetland scale, underscoring the disproportionate role of SGD in modulating saltmarsh carbon sequestration dynamics. Remarkably, SGD contributed to ∼65 % of the total carbon sources in the estuary, indicating its profound control over carbon budgets throughout the continuum. These findings emphasize the presence of SGD-derived carbon outwelling as a novel marine carbon cycling mechanism in the continuum.
