The residue pattern was dominated by the well-known HNP 2,4,6-tribromophenol (TBP, 27-420 ng/g lipid, fillet) and the man-made PCB 153 (29-100 ng/g lipid, fillet). Indications on the presence of polybrominated dibenzo-p-dioxins (PBDDs) could be verified in ten of 12 samples by two independent gas chromatography with mass spectrometry (GC/MS) methods. Synthesis of a PBDD mixture, followed by enrichment of individual PBDD congeners by countercurrent chromatography and their calibration by GC with flame ionization detection (GC/FID) enabled the (semi-)quantitation of individual PBDD congeners, ranging from 2 to 1100 ng/g lipids. The PBDDs which were most likely naturally produced were even the most abundant substance class in some of the samples. A new approach of considering the total weights of the entire fillet, liver, and brain samples, respectively, enabled determining the total amounts of compounds for the distribution within the fish. This data treatment indicated differences between HNPs and POPs. Namely, >60% of the determined HNPs but only 36-53% of the POPs were stored in the fillet of the fish. Spatial differences between HNPs (TBP) and POPs (PCBs) were also found with TBP becoming more abundant with increasing distance from the coast.</p>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"229 ","pages":"119778"},"PeriodicalIF":4.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147775887","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}

PBDEs and PFAS are reported in marine sediments from this region for the first time. After studying grain size, total organic carbon contents and ²¹⁰Pb-dating of sediment cores, the levels of these pollutants are concluded to be low at most locations. An exception is several coastal locations off the ports of Varna and Burgas and the Kamchia River estuary, where strongly elevated levels of several pollutants were found. Possible sources for these are discussed based on compound or congener composition. Contaminant levels in sediments from the remaining locations were mostly determined by sediment characteristics, the higher levels found in fine-grained sediments in the open sea. Two of the sediment cores demonstrated an increase in pyrogenic PAHs in recent times, attributed to anthropogenic impacts, while the metals were largely at their natural background level determined through core analysis.

The study assessed size-partitioned plastic pollution in water, sediment, and two edible mollusc species, <ce:italic>Telescopium telescopium</ce:italic> and <ce:italic>Crassostrea madrasensis</ce:italic>, from the Ayiramthengu Mangrove Forest (AMF), an ecologically significant environmental hotspot along the southwest coast of India. The distinct habitats, contrasting feeding strategies, and prominence of these edible molluscs in local diets highlight their ecological and dietary significance, making them suitable sentinel species for cross-matrix microplastic (MP) assessment. MP contamination assessed following the NOAA protocols in AMF revealed a high abundance of macro-, meso-, and microplastics in the sediments of Site 1. All analyses were performed using procedural blanks and rigorous contamination controls. The evident spatial variations observed in MP distribution resulted from differences in anthropogenic activities and hydrodynamic transport. Polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polystyrene (PS) were the major MP contaminants. The pronounced spatial variation in MP distribution, as reflected by the particle abundance, indicated that mangrove sediments act as the primary reservoir, retaining more particles than the surrounding water, thereby enhancing their bioavailability to molluscs and dietary exposure. However, direct implications of MP on human health were not evaluated in this study. The high Polymer Hazard Index and Pollution Load Index of each site indicate the intensity of MP pollution in AMF. Overall, the results of the study provide season-specific patterns and baseline information for future monitoring and management of plastic pollution, prioritizing targeted debris removal and restoration along with implementation of proper dietary guidelines.","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"52 1","pages":"120047"},"PeriodicalIF":5.8,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148402642","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}

Crabs and fish are widely recognized as effective bioindicators of environmental contamination due to their capacity to bioaccumulate and metabolize toxic compounds in specific biological fluids. Crabs can concentrate contaminants in hemolymph and urine, whereas fish preferentially accumulate metabolized compounds in bile, particularly those undergoing hepatic biotransformation. This study assessed the ecosystem health of mangrove located along the BEM, in the Jaguaribe River estuary (Ceará, Brazil), by determining 6 metabolites of polycyclic aromatic hydrocarbons (OH-PAHs) and 12 bisphenols in fish bile and in crab hemolymph and urine. Analyses were performed using high-performance liquid chromatography with fluorescence detection (HPLC-FD). OH-PAHs and bisphenols were selected due to their widespread occurrence, persistence, and toxicological relevance, including endocrine-disrupting, mutagenic and carcinogenic effects. The results revealed elevated concentrations of ∑OH-PAHs (0.49-238.1 ng/mL) and ∑Bisphenols (1.77-223,653.51 ng/mL), indicating substantial exposure of local biota to anthropogenic contaminants. The occurrence of carcinogenic and endocrine-disrupting compounds provides clear evidence of chronic chemical stress and declining ecosystem health, reinforcing the need for integrated environmental monitoring. This study shows that contaminant levels in urine, hemolymph, and bile provide complementary and sensitive indicators of ecosystem health in tropical mangroves. The three matrices captured different aspects of exposure and metabolism, with bile reflecting hydrophobic PAHs, urine indicating soluble metabolites and hemolymph signaling short-term physiological responses.</p>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"228 ","pages":"119597"},"PeriodicalIF":4.9,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147521350","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}

Microplastics have been detected in edible salt, representing an emerging exposure pathway due to the potential ingestion of these particles. However, limited information is available on how microplastic levels in salt vary across harvesting season and among different brine sources used in production. In this study, salts produced from seawater and groundwater brines were analyzed at the beginning and end of the salt harvesting season, to identify, quantify and characterize microplastic contamination. Microplastics were extracted, counted, classified according to their form, and chemically characterized using FTIR spectroscopy. The highest abundances were observed at the end of the harvesting season, with ranges between 1288 ± 38 - 1884 ± 718 MPs/kg in seawater salts and 797 ± 53 - 1331 ± 406 MPs/kg in groundwater salts. Seawater-derived salts exhibited one of the highest mean microplastic abundances reported to date in edible salt worldwide. Across all samples, microplastics showed similar characteristics, with fibers accounting for more than 90% of particles and an average size of approximately 1 mm. Microplastic abundance varied significantly between the beginning and end of the harvesting season; however, no significant differences were observed between brine sources.
