Seafood is an important source for meeting future global nutrient demands. However, it also contributes disproportionately to the radiological ingestion dose of more than five billion world consumers– up to ∼70%–80% of the total-foods dose in some countries. Although numerous studies report seafood doses in specific populations, there is still no comprehensive evaluation answering basic questions such as “what is the ingestion dose to the average global seafood consumer?” Analysis of 238 worldwide seafood dose estimates suggests that typical adult consumers receive from 0.13 to 0.21 mSv, with a likely best estimate of 0.15 mSv per annual seafood intake. Those consuming large amounts of seafood, particularly bivalves, may experience ingestion doses exceeding 1 mSv per annual intake, surpassing other routine background dose sources. The published studies suggest that doses of 3 mSv or greater are surpassed in about 150 million adult seafood consumers worldwide. Almost all this dose comes from the natural radionuclides that are prevalent in marine systems–especially 210Po. While trace levels of anthropogenic radionuclides are ubiquitous in seafoods (e.g.,137Cs and 239Pu), the added dose from these is typically orders of magnitude lower. Even following the large-scale releases from the Fukushima accident, with food safety controls in place, the additional dose to consumers in Japan was small relative to routine dose from natural background radionuclides. However, the worldwide seafood dose estimates span seven orders of magnitude, indicating a need for an assessment that integrates global seafood radionuclide data as well as incorporating changes in seafood consumption and production patterns.

Mercury (Hg) is a global pollutant that has attracted widespread attention due to its potent toxicity to humans. The transformations of Hg are critical to its global cycling and human exposure risk, considering that different Hg forms possess various mobility and toxicity. It is, therefore, essential to explore the mechanisms of Hg transformations. Both biotic and abiotic factors mediate Hg transformations in the environments, while the latter has not been sufficiently recognized, among which reactive oxygen species (ROS) are ubiquitous yet potentially overlooked drivers. This insufficient recognition of ROS-mediated Hg transformations impeded our understanding of Hg biogeochemistry. Herein, we summarized the generation mechanisms of ROS in the atmosphere, natural water, and soil, and elucidated ROS involvement in Hg transformations, including MeHg degradation, Hg0 oxidation, and Hg(II) reduction. Then, approaches for exploring the role of ROS in Hg transformations were introduced, including ROS detection, quenching, generation, and DFT calculations. By summarizing the implications of ROS-mediated Hg transformations for Hg biogeochemical cycling and proposing potential challenges in further studies, we highlight the importance and necessity of studying this driving force in Hg biogeochemistry.

Rare earth elements (REE) are recognized as emerging pollutants due to their widespread use in modern society (e.g., in the production of electronics, renewable energy technologies, and advanced medical devices) which leads to anthropogenically elevated concentrations in the environment with potential consequences for ecosystem health. This article critically reviews the current scientific knowledge on aquatic bioavailability and toxicity of REE and focuses on pitfalls that could influence the outcome of ecotoxicity tests. After passing our quality criteria, we reviewed 38 papers on the ecotoxicity of REE in depth. Most studies focused on freshwater environments, indicating a need for more research on marine ecosystems, particularly on marine vertebrates. The results showed that heavy REE tend to be more toxic than light REE to aquatic organisms. Critical aspects for biotesting REE include complexation with ions such as phosphates (nutrient in algae tests) and carbonates. Carbonate complexation decreases potentially bioavailable aqueous REE species and may lower toxicity at increasing water hardness, although this may also be caused by competition of REE3+ and Ca2+ for the same binding sites in organisms. REE have a high tendency to adsorb to glass and it is recommended to use vessels made of polyethylene terephthalate or polycarbonate instead. More research is needed on chemical speciation and the interaction of REE with various organisms, also in multi-species mesocosm studies. A robust aquatic risk assessment on REE requires information on nominal and measured concentrations in both acute and chronic ecotoxicological bioassays as well as a thorough characterization of exposure.

Organophosphate esters (OPEs), a group of synthetic chemicals widely used as flame retardants and plasticizers, have garnered significant international attention due to their adverse effects on the environment and human health. Traditionally, environmental OPEs are thought to originate via direct emissions. Recent evidence suggests that OPEs also have an important indirect source: The transformation of organophosphite antioxidants (another group of mass-produced commercial chemicals) to OPEs via atmospheric chemical reactions. This indirect source can lead to the formation of secondary OPEs (SOPEs) such as tris(2,4-di-tert-butylphenyl) phosphate (TDtBPP), which are widely distributed in the global environment and have distinct physiochemical and toxic properties compared with the well-studied primary OPEs. Therefore, there is an urgent need to obtain a strong fundamental knowledge of SOPEs. This review summarizes the current understanding of the sources, environmental occurrence, human exposure pathways, and environmental hazards of SOPEs. They have been detected in various environmental matrices such as air, soil, and indoor dust, as well as in consumer products such as face masks and foodstuffs. Notably, the reported SOPE concentrations are higher than most primary OPEs. Human exposure pathways related to SOPEs include dietary intake, dust ingestion, hand-to-mouth contact, dermal absorption, and air inhalation. Additionally, risk evaluation indicates that SOPEs are more persistent in the environment and in organisms, and may pose a higher risk than the primary OPEs. Finally, by summarizing the current advances and remaining challenges for the investigation of SOPEs, we propose future research directions regarding their environmental monitoring needs, transformation chemistry, environmental impact, and health effect.

The vigorous development of nuclear power is one of the main strategies to solve the energy crisis and environmental pollution due to clean and high energy density of nuclear energy. As the main nuclear fuel, uranium is not only the shortage of terrestrial resource but also pose potential threat to the environment. To figure out these dilemma, various polymers have been widely developed to remove U(VI) from wastewater or extract U(VI) from seawater due to abundant reactive sites, high adsorption efficiency, large surface areas and controlled porous structure. Herein, the recent advances concerning U(VI) removal from seawater or wastewater on various polymer-bearing adsorbents (i.e., metal-organic frameworks (MOFs), covalent-organic frameworks (COFs) and the other polymers) were summarized at large. The effect of different modification methods, influencing factors and interaction mechanism of U(VI) on these polymers were reviewed in details. Finally, the current problems as well as future direction of various polymer adsorbents toward U(VI) removal was provided. The review hopefully provides high-efficiency polymer adsorbents for the removal of uranium from aqueous solution or natural seawater.

Biological carbon fixation is essential to the Earth’s carbon cycle and serves as an effective means of converting CO2 and managing carbon emissions. Chemoautotrophic microorganisms, known for their unique metabolic strategies and environmental adaptability, play a significant role in this process. They can convert CO2 into valuable organic products, addressing the otherwise limited use of CO2. However, the potential of chemoautotrophic microorganisms for biological carbon fixation in controlled environments has not been fully explored. This review aims to evaluate the current state of research on the carbon fixation capabilities of chemoautotrophic microorganisms in artificially controlled system. It examines the factors affecting bacterial growth and expounds optimization strategies one by one to enhance biological carbon fixation efficiency. Furthermore, the review details the applications of chemoautotrophs cultivated in controlled systems, which include increasing biological productivity in natural habitats, reducing carbon emissions in specific scenarios, and producing high-value byproducts. The discussion highlights both the advantages and challenges of these applications, providing critical insights into the regulation and practical use of chemoautotrophic carbon fixation technology.

Bisphenol A (BPA) is an emerging contaminant that disrupts endocrine systems and poses significant risks to organisms. It is increasingly detected in municipal wastewater due to its widespread use and high production volume. Despite this, gaps remain in understanding the sources of BPA in municipal wastewater, its effects on nitrification and denitrification, and the potential for its co-removal with ammonia or nitrate during biological nitrogen removal processes. This review first examines the sources of BPA, primarily from industrial effluents and landfill leachates, which enter wastewater treatment plants alongside domestic sewage. Additionally, it meticulously elucidated the influences, co-removal with nitrogen performance, and biotransformation mechanisms of BPA during nitrification and denitrification processes, shedding light on biotransformation pathways, functional microbes and key enzymes. While there is no consensus on BPA removal in anoxic conditions, aerobic environments support its biodegradation through various microorganisms. Lastly, the potential for microbial cooperation to enhance BPA and nitrogen co-removal is discussed, focusing on bacterial mutual alliances and bacteria-algae metabolic interaction consortiums. This review provides valuable guidance for the synergistic removal of BPA and nitrogen in wastewater treatment processes.
双酚 A（BPA）是一种新出现的污染物，会扰乱内分泌系统，对生物体构成重大风险。由于双酚 A 的广泛使用和高产量，在城市污水中检测到双酚 A 的情况越来越多。尽管如此，人们对城市污水中双酚 A 的来源、双酚 A 对硝化和反硝化的影响以及在生物脱氮过程中双酚 A 与氨或硝酸盐共同去除的可能性的了解仍然存在差距。本综述首先探讨了双酚 A 的来源，主要是与生活污水一起进入污水处理厂的工业废水和垃圾填埋场沥滤液。此外，它还细致地阐明了双酚 A 在硝化和反硝化过程中的影响、与氮性能的共同去除以及生物转化机制，揭示了生物转化途径、功能微生物和关键酶。虽然在缺氧条件下去除双酚 A 尚无共识，但有氧环境可通过各种微生物支持双酚 A 的生物降解。最后，重点讨论了细菌相互联盟和细菌-藻类代谢相互作用联合体，讨论了微生物合作加强双酚 A 和氮共同去除的潜力。本综述为在废水处理过程中协同去除双酚 A 和氮提供了宝贵的指导。

Research on sensor materials has expanded with the advancement of sensing technologies across industries. Carbon dots (CDs) derived from organic waste and biomass have attracted widespread interest in sensing applications with their prominent properties (e.g., photoluminescence and biocompatibility). The use of non-biomass waste (NBW) as a raw material thus becomes important to make their production process sustainable without additional treatments to cause environmental pollution. Due to scarcity of research on NBW-based CDs, this review explores the synthesis methods, properties, and sensing applications of NBW-based CDs. The potential of NBW-based CD sensors for metal ions (e.g., Fe3+ and Cu2+) and humidity has been evaluated in various respects. In the case of Fe3+ and Cu2+, CDs derived from waste medical gloves and polyolefin pyrolysis residue exhibit the lowest limit of detection values of 0.29 nM and 6 nM, respectively, among all sensors examined on parallel basis. In the case of humidity, graphite-based CDs exhibit the best performance, with a minimum response time of 15 s. This review overall highlights the challenges and opportunities for the expanded application of NBW-based CDs toward the construction of efficient sensing systems based on performance evaluations.
随着各行各业传感技术的发展，对传感材料的研究也在不断扩大。从有机废物和生物质中提取的碳点（CDs）以其突出的特性（如光致发光和生物相容性）在传感应用中引起了广泛的兴趣。因此，使用非生物质废弃物（NBW）作为原材料，使其生产过程可持续发展而无需额外处理，从而避免造成环境污染，就变得非常重要。由于有关基于 NBW 的光盘的研究很少，本综述将探讨基于 NBW 的光盘的合成方法、特性和传感应用。对基于 NBW 的 CD 传感器在金属离子（如 Fe3+ 和 Cu2+）和湿度方面的潜力进行了多方面的评估。就 Fe3+ 和 Cu2+ 而言，从废弃医用手套和聚烯烃热解残渣中提取的 CD 在所有平行检测的传感器中表现出最低的检测限值，分别为 0.29 nM 和 6 nM。在湿度方面，石墨基 CD 的性能最佳，响应时间最短为 15 秒。本综述从总体上强调了基于 NBW 的光盘在构建基于性能评估的高效传感系统方面的挑战和机遇。

Adipogenesis, the process by which preadipocytes differentiate into mature fat cells, is closely associated with the development of obesity and metabolic syndrome. Identifying and classifying chemicals interfering with adipogenesis are needed for both human health and the environment. However, challenges remain in testing and interpreting data on chemical-induced adipogenesis. This study reviewed available in vitro fish adipogenesis assays, summarized the effects of chemicals on fish adipogenesis, and compared chemical-induced adipogenesis results between mammalian and fish assays. Primary fish adipocyte cultures have been developed for eight species of freshwater and seawater fish, with significant variation in culture media, particularly in adipogenic cocktails used. While lipid mixtures can enhance adipogenesis, they may not affect the commitment of multipotent progenitor cells to adipocyte linage and may not always be necessary for fish adipocyte cultures. Differences in chemical-induced adipogenesis between mammalian and fish assays may result not from species differences, but from variations in culture conditions, such as the composition of adipogenic cocktails and lipid mixtures, which can obscure the effects of chemicals on adipogenesis. There is a need for standardized adipogenesis assays, and developing OECD test guidelines is essential for their regulatory use. Fish adipogenesis assays can detect mechanisms of endocrine disruption that may not be apparent in mammalian cells, providing insights into mechanisms of action relevant to both human health and the environment. It is crucial to integrate adipogenesis data into the regulatory frameworks by expanding data requirements to include adipogenesis assays and developing reliability criteria for assessing adipogenesis studies.
