This study assessed the proximate composition and heavy metal (HM) contamination of the jellyfish Rhizostoma octopus collected from the Cox's Bazar coast, Bangladesh. To minimize post-mortem alterations, three specimens were collected alive from fishermen's nets near the shoreline. HM concentrations were determined using atomic absorption spectroscopy. The mean concentrations of metals and minerals decreased in the order: Na > Mg > K > Ca > Fe > Zn > Mn > Cu > Pb > Ni > Co > Cd > Cr > As. Proximate composition analysis (sun-dried weight basis) showed that ash was predominant (46.84-54.58%), followed by protein (25.79-27.76%), moisture (16.47-18.73%), carbohydrate (0.21-9.74%), and fat (0.46-0.79%). Principal component analysis identified two major components explaining most of the variance in metal contents, while hierarchical cluster analysis revealed similar accumulation patterns among metals. Health risk assessment suggested that individual target hazard quotient values for all metals were below 1, and the overall hazard index was also below 1, suggesting no significant non-carcinogenic risk. However, carcinogenic risk estimates were higher for children than adults, with Cd was estimated to exceed the USEPA acceptable threshold for children, showing a value of 2.48E-04. Despite the advantage of live sampling, the small sample size and limited spatial and temporal coverage restrict the representativeness of the results. Therefore, larger-scale and long-term studies are required to validate the safety of R. octopus for human consumption and to support its potential as a sustainable food resource within the blue economy.

本研究评估了从孟加拉国考克斯巴扎尔海岸采集的水母根口章鱼的近似组成和重金属污染。为了尽量减少死后的变化,从海岸线附近渔民的网中收集了三个活标本。用原子吸收光谱法测定HM浓度。金属和矿物的平均浓度依次为:Na > Mg > K > Ca > Fe > Zn > Mn > Cu > Pb > Ni > Co > Cd > Cr > As。比邻成分分析(以晒干重量为基础)表明,其主要成分为灰分(46.84 ~ 54.58%),其次为蛋白质(25.79 ~ 27.76%)、水分(16.47 ~ 18.73%)、碳水化合物(0.21 ~ 9.74%)和脂肪(0.46 ~ 0.79%)。主成分分析确定了两个主要成分解释了金属含量的大部分差异,而层次聚类分析揭示了金属之间相似的积累模式。健康风险评估表明,所有金属的个体目标危害商值均低于1,总体危害指数也低于1,表明无显著的非致癌风险。然而,儿童的致癌风险估计高于成人,Cd估计超过了美国环保署对儿童的可接受阈值,显示值为2.48E-04。尽管现场抽样具有优势,但小样本量和有限的时空覆盖限制了结果的代表性。因此,需要进行更大规模和长期的研究,以验证章鱼章鱼供人类食用的安全性,并支持其作为蓝色经济中可持续食物资源的潜力。

This study presents a 3D hydrodynamic simulation of coastal circulation coupled with copper advection emanating from Quintero Bay, in the Valparaíso region. The bay is home to an important industrial complex and has a history of heavy metal contamination due to a copper smelter located in its northern sector. This study aims to simulate the distribution of contamination from existing sources and identify potential risk scenarios associated with copper exposure in water and sediment. A simple data assimilation method has been developed to capture elements of coastal wind not well represented by existing models used for wind forcing. The simulation period represents an austral summer, and several circulation patterns have been identified in response to external forcings. Two different point sources are considered, one within the bay (source 1), and the other just outside the south side of the bay (source 2). Simulations show advection of copper towards coastal areas north of the bay in trace concentrations from both sources, with instances at certain points within the bay when recommended thresholds for chronic and acute exposure are surpassed. Source 1 shows advection predominantly leaving the north side of the bay in surface waters, while source 2 shows advection in bottom waters periodically entering the south side of the bay. These results are consistent with existing local studies of copper concentrations in the water and sediment.

本文研究了Valparaíso地区沿海环流与铜平流耦合的三维水动力模拟。这个海湾是一个重要的工业综合体的所在地,由于位于其北部的铜冶炼厂,它有重金属污染的历史。本研究旨在模拟现有污染源的污染分布,并确定与水和沉积物中铜暴露相关的潜在风险情景。一种简单的资料同化方法已被开发出来,用于捕捉现有风强迫模式不能很好地表示的沿海风要素。模拟期代表一个南方夏季,并且已经确定了响应外部强迫的几种环流型态。考虑两个不同的点源,一个在海湾内(源1),另一个刚好在海湾的南侧外(源2)。模拟显示,来自两个来源的微量铜向海湾北部沿海地区平流,在海湾内的某些地点,慢性和急性接触的建议阈值超过了。源1显示平流主要在地表水中离开海湾的北侧,而源2显示底部水的平流周期性地进入海湾的南侧。这些结果与现有的当地对水和沉积物中铜浓度的研究相一致。

This study investigated the occurrence, distribution, and polymer composition of MP in 30 commercially important fish species (N = 600 specimens) collected from three major landing centres along the Thoothukudi coast from December 2024 to May 2025. Employing hydrogen peroxide digestion and ATR-FTIR spectroscopy for particle identification. Extracted MPs were identified based on their molecular composition, with a library match of >80%. MP concentrations varied significantly among species (p < 0.05), with the highest accumulation in the gastrointestinal tract (3.67-8.75 particles/fish), followed by gills (1.93-4.27 particles/fish) and muscle tissue (1.2-3.6 particles/5 g wet weight). Carnivorous species exhibited significantly higher MP burdens than planktivorous species, with Epinephelus longispinis showing maximum gut contamination (8.75 ± 2.36 particles/fish). Among 1446 particles analyzed, polyethylene (37.47%) and polypropylene (27.20%) dominated polymer composition, with fibers comprising 85% of particle morphology. A human health risk assessment revealed that estimated daily intake values ranged from 0.047 to 0.159 particles/kg body weight/day. The pollution risk (PRI) and hazard index (PHI) of most analyzed fish species ranged from 335 to 668 and 265 to 302, indicating considerable to medium hazard risk. These findings demonstrate widespread MP contamination across trophic levels in Thoothukudi's marine ecosystem, highlighting urgent needs for targeted pollution mitigation strategies and continued monitoring of MP bioaccumulation in commercially harvested fish species to protect both ecosystem integrity and human food security.

Coastal wetlands are increasingly exposed to multiple pollutants, including metal and per- and polyfluoroalkyl substances (PFAS). However, metal and PFAS co-occurrence and interactions in mangrove sediments remain poorly understood. This study provides one of the first investigations of metal and PFAS co-distribution in mangrove sediment cores across two contrasting tropical estuarine systems and between old and young mangrove forest sites. No vertical stratification of contaminants was observed, likely due to intense bioturbation. Distinct spatial trends emerged between and within estuaries, reflecting differences in local sources, salinity-driven partitioning, and dilution downstream. Sediments near urbanized areas generally contained higher concentrations of metals and PFAS. Mangrove age influenced contaminant levels, possibly through differences in sediment accretion and hydrological conditions, though these effects were spatially variable. Sediment texture and organic carbon content were relatively uniform, yielding few and generally weak correlations with contaminant concentrations. Significant associations between metals and PFAS suggest co-distribution mechanisms influenced by shared geochemical factors. While metal concentrations indicated moderate contamination and overall limited ecological risk, PFAS levels often exceeded those reported for heavily impacted estuarine systems. These findings highlight the need for source control, long-term monitoring, and multidisciplinary studies integrating hydrology, geochemistry, and ecotoxicology to protect the resilience of mangrove ecosystems facing intensifying anthropogenic pressures.

沿海湿地越来越多地暴露于多种污染物,包括金属和全氟烷基和多氟烷基物质。然而,金属和PFAS在红树林沉积物中的共生和相互作用仍然知之甚少。这项研究提供了金属和PFAS共同分布在两个不同的热带河口系统的红树林沉积物岩心中,以及在老红树林和年轻红树林之间的首次调查之一。没有观察到污染物的垂直分层,可能是由于强烈的生物扰动。河口之间和河口内部出现了明显的空间趋势,反映了当地来源、盐度驱动的分区和下游稀释的差异。城市化地区附近的沉积物通常含有较高浓度的金属和PFAS。红树林年龄影响污染物水平,可能是通过沉积物增加和水文条件的差异,尽管这些影响在空间上是可变的。沉积物结构和有机碳含量相对均匀,与污染物浓度的相关性很少,通常很弱。金属与PFAS之间的显著相关性表明,共同的地球化学因子影响了共分布机制。虽然金属浓度表明中度污染和总体有限的生态风险,但PFAS水平往往超过严重受影响的河口系统的报告。这些发现突出表明,需要进行源头控制、长期监测和综合水文学、地球化学和生态毒理学的多学科研究,以保护红树林生态系统在日益加剧的人为压力下的恢复能力。

However, metal and PFAS co-occurrence and interactions in mangrove sediments remain poorly understood. This study provides one of the first investigations of metal and PFAS co-distribution in mangrove sediment cores across two contrasting tropical estuarine systems and between old and young mangrove forest sites. No vertical stratification of contaminants was observed, likely due to intense bioturbation. Distinct spatial trends emerged between and within estuaries, reflecting differences in local sources, salinity-driven partitioning, and dilution downstream. Sediments near urbanized areas generally contained higher concentrations of metals and PFAS. Mangrove age influenced contaminant levels, possibly through differences in sediment accretion and hydrological conditions, though these effects were spatially variable. Sediment texture and organic carbon content were relatively uniform, yielding few and generally weak correlations with contaminant concentrations. Significant associations between metals and PFAS suggest co-distribution mechanisms influenced by shared geochemical factors. While metal concentrations indicated moderate contamination and overall limited ecological risk, PFAS levels often exceeded those reported for heavily impacted estuarine systems.
