Accumulation of per- and polyfluoroalkyl substances (PFAS) in soil, sediment, and water poses significant public health risks due to their persistence and potential toxicity. PFAS compound possesses strong C – F bonds that require very high energy to break, making current technology unsustainable and challenging for large-scale treatment. Recent mechanistic insights into microbial degradation of PFAS offer promising solutions for their sustainable degradation. Specifically, bioelectrochemical systems can effectively break the strong C – F bonds in PFAS using high-energy electrons generated from electroactive microbes at a conductive anode electrode, achieving an astonishing removal efficiency of up to 96 %. However, these systems are still experimental, requiring further optimization for successful large-scale applications. This concise yet detailed review aims to enhance understanding of the emergence of PFAS as a pervasive potent chemical, microbe-assisted degradation mechanisms, and microbial community analysis, guiding future research and policy development for improved public health and environmental management.

全氟烷基和多氟烷基物质（PFAS）在土壤、沉积物和水中的积累，由于其持久性和潜在毒性，构成重大的公共健康风险。PFAS化合物具有很强的C - F键，需要非常高的能量才能打破，这使得目前的技术不可持续，并且对大规模处理具有挑战性。最近对PFAS微生物降解机理的研究为其可持续降解提供了有希望的解决方案。具体来说，生物电化学系统可以利用导电阳极电极上电活性微生物产生的高能电子有效地破坏PFAS中的强C - F键，达到高达96%的惊人去除效率。然而，这些系统仍处于实验阶段，需要进一步优化才能成功地大规模应用。这篇简明而详细的综述旨在加强对PFAS作为一种普遍有效的化学物质的出现、微生物辅助降解机制和微生物群落分析的理解，指导未来的研究和政策制定，以改善公共卫生和环境管理。

Over the past two decades, global consumption of agrochemicals has risen considerably. These chemicals are hazardous to air, soil, freshwater, marine microorganisms, plants, animals, and humans. This review examines worldwide agrochemical consumption trends from 2001 to 2021. It discusses environmental emissions of nitrous oxide, nitric oxide, and ammonia from nitrogen fertilizers. The review highlights the impact of various pesticide residues on air, soil, water, animals, and human health. This review also explores the influence of agrochemical pollution on climatic change, including its contribution to greenhouse gas emissions and its effects on temperature and rainfall patterns. Finally, we outline the global actions undertaken by organizations such as UNFAO, UNEP, WHO, and EC to address agrochemical pollution and promote control strategies. This review underscores the negative effects of agrochemical pollution on ecosystems and suggests that reducing agrochemical usage, implementing integrated pest management, and promoting organic farming can help mitigate its environmental impact.

Bacillus thuringiensis (Bt) microbial insecticides owe their effectiveness mostly to Cry toxins that target specific insects. Bt products are made of spores of Bt and crystals of toxins, Cry toxins being also used in genetically modified crops. Although widely used in agriculture, data on their long-term effects are scarce. Because microbial insecticides are essential to the development of sustainable agriculture, more research is needed to understand the unintended effects of Bt products and to improve Bt products and applications, ultimately leading to safer agricultural practices. In this review, we focus on recent studies dealing with the persistence and unintended effects of the main components of Bt insecticidal products, namely Cry toxins, spores and vegetative cells.

苏云金芽孢杆菌（Bt）微生物杀虫剂的有效性主要归功于针对特定昆虫的Cry毒素。Bt产品是由Bt孢子和毒素结晶制成的，这些毒素也被用于转基因作物。尽管它们在农业中广泛使用，但关于其长期影响的数据却很少。由于微生物杀虫剂对可持续农业的发展至关重要，因此需要更多的研究来了解Bt产品的意外影响，并改进Bt产品和应用，最终导致更安全的农业实践。在这篇综述中，我们重点介绍了最近关于Bt杀虫产品的主要成分，即Cry毒素、孢子和营养细胞的持久性和意外效应的研究。

Agricultural soil fertility increases when livestock manure is used as an organic fertilizer. However, it spreads antibiotic resistance genes (ARGs) across agricultural land, endangering food safety and the environment. The processes of ARG diffusion in soil-crop systems were examined in the present study, along with the effects of plant root exudates and soil physicochemical characteristics. Effects of soil moisture, pH, and REDOX potential on microbial communities and ARG dynamics were analyzed, along with the ARG transfer to plants through root uptake and endophytic colonization. Furthermore, the implications of ARG dissemination for soil health, crop safety, and human health were examined, highlighting the necessity for a thorough understanding of these interactions to formulate effective ARG mitigation strategies. This review will aid future research on the long-term environmental impact of ARGs and assist in developing effective control measures to promote sustainable agricultural development and food safety.

牲畜粪便作为有机肥使用，农业土壤肥力增加。然而，它在农业用地上传播抗生素耐药基因（ARGs），危及食品安全和环境。本研究考察了ARG在土壤-作物系统中的扩散过程，以及植物根系分泌物和土壤理化特性的影响。分析了土壤湿度、pH值和氧化还原电位对微生物群落和ARG动态的影响，以及ARG通过根吸收和内生定殖向植物的转移。此外，还审查了ARG传播对土壤健康、作物安全和人类健康的影响，强调有必要彻底了解这些相互作用，以制定有效的ARG缓解战略。这将有助于进一步研究ARGs对环境的长期影响，并有助于制定有效的控制措施，以促进农业可持续发展和食品安全。

Plant-based biorational insecticides such as essential oils and extracts are complex mixtures of molecules that exhibit selective toxicity toward insect pests while minimizing harm to nontarget organisms (NTOs) such as pollinators, parasitoids, and predators. Recent investigations using clove (Syzygium aromaticum), Negramina (Siparuna guianensis), and common fig (Ficus carica) indicate that their essential oils and extracts generally exhibit lower toxicity to beneficial organisms than to target pests, potentially due to ecological factors like application timing. This review focuses on physiological selectivity, which involves preferential interactions between plant compounds and targets in pests versus NTOs. Advances in computational methods and genetic engineering enable the prediction of these interactions, revealing that plant compounds (e.g. β-caryophyllene, psoralen, sesquirosefuran, and eugenol) bind more effectively to specific enzymes and receptors in pest insects. By exploring these mechanisms, we highlight the potential of plant-based insecticides to reduce risks to NTOs and their role in sustainable pest management programs.

以植物为基础的生物杀虫剂，如精油和提取物，是分子的复杂混合物，对害虫表现出选择性毒性，同时最大限度地减少对非目标生物（nto）的伤害，如传粉者、寄生蜂和捕食者。最近对丁香（Syzygium aromaticum）、Negramina （Siparuna guianensis）和无花果（Ficus carica）的研究表明，它们的精油和提取物对有益生物的毒性通常低于对害虫的毒性，这可能是由于施用时间等生态因素所致。本文综述了植物的生理选择性，即植物化合物与靶点在害虫和NTOs中的优先相互作用。计算方法和基因工程的进步使预测这些相互作用成为可能，揭示了植物化合物（如β-石竹烯、补骨脂素、倍半玫瑰呋喃和丁香酚）更有效地与害虫体内的特定酶和受体结合。通过探索这些机制，我们强调了植物基杀虫剂在降低nto风险方面的潜力及其在可持续害虫管理计划中的作用。

Rare earth elements (REEs) are essential in several industries, particularly green technologies, but their increasing use is raising environmental concerns. This review examines the impact of REEs on ecosystems under climate change stressors. A bibliometric analysis revealed a scarcity of ecotoxicological studies, with a major focus on aquatic organisms due to the high vulnerability of aquatic ecosystems. Results indicate that some REEs may induce oxidative stress and disrupt physiological processes. Future research should prioritize interactions between REEs and other contaminants, improve experimental relevance, and increase species diversity to fully understand ecological effects.

稀土元素（ree）在许多行业，特别是绿色技术中都是必不可少的，但它们的使用越来越多，引起了人们对环境的担忧。本文综述了气候变化胁迫下稀土元素对生态系统的影响。文献计量学分析显示，生态毒理学研究缺乏，由于水生生态系统的高度脆弱性，主要集中在水生生物上。结果表明，某些稀土元素可诱导氧化应激，扰乱生理过程。未来的研究应优先考虑稀土元素与其他污染物之间的相互作用，提高实验相关性，增加物种多样性，以充分了解生态效应。

Organophosphorus esters (OPEs) are extensively used as flame retardants and plasticizers in various industrial products. However, their release into the environment and associated toxicity have garnered increasing research attention. This study provides an overview of OPEs in soil, focusing on pollution sources, distribution, migration, risks, and transformation. Existing studies suggest that OPEs are widely present in soil, with concentrations ranging from non-detectable levels to 80,300 ng/g. These compounds can migrate to other environmental media through processes such as adsorption, desorption, volatilization, and bioaccumulation. OPEs exhibit reproductive toxicity, developmental toxicity, and neurotoxicity to soil fauna. In soil, OPEs can undergo hydrolysis and photolysis to degrade into diesters or monoesters, or they can biodegrade through specific enzyme-catalyzed reactions. Finally, this study discusses unresolved issues and future research directions on OPEs in soil, aiming to provide valuable references for related fields.

有机磷酯（OPEs）广泛用于各种工业产品的阻燃剂和增塑剂。然而，它们释放到环境中以及相关的毒性已经引起了越来越多的研究关注。本研究概述了土壤中有机磷农药的污染来源、分布、迁移、风险和转化。现有研究表明，OPEs广泛存在于土壤中，浓度从无法检测到80,300纳克/克不等。这些化合物可以通过吸附、解吸、挥发和生物积累等过程迁移到其他环境介质中。OPEs对土壤动物表现出生殖毒性、发育毒性和神经毒性。在土壤中，OPEs可以通过水解和光解降解为二酯或单酯，也可以通过特定的酶催化反应进行生物降解。最后，本研究对土壤中OPEs存在的问题和未来的研究方向进行了探讨，旨在为相关领域提供有价值的参考。

Arsenic, the 20th most abundant element in the Earth's crust, is a significant environmental and health concern, prominently featured on priority lists of hazardous substances. Due to its high mobilization and persistence in both natural and anthropogenic environments, chronic exposure to arsenic in groundwater has posed severe public health risks. This review focuses on the current status of arsenic contamination, the release mechanism, the mobilization, and remediation of arsenic-polluted groundwater in major river deltas in Vietnam. The most arsenic-polluted regions in Vietnam are the Red River Delta (up to 3050 μg/L) and the Mekong River Delta (up to 1351 μg/L), far exceeding the permissible limit value of the World Health Organization (WHO) guidelines for arsenic in groundwater at 10 μg/L. Arsenic levels are unevenly distributed due to the differences in the geochemical composition of the aquifer and hydrological flow patterns. Utilizing natural laterite adsorption is proposed as a remediation strategy to limit the risks of arsenic spread in groundwater and its impact on public health.

砷是地壳中含量第20多的元素，是一个重大的环境和健康问题，在危险物质优先清单中占有突出地位。由于其在自然和人为环境中的高度动员和持久性，长期接触地下水中的砷已构成严重的公共健康风险。本文综述了越南主要河流三角洲地下水砷污染现状、砷释放机制、砷污染的动员和修复措施。越南砷污染最严重的地区是红河三角洲（高达3050 μg/L）和湄公河三角洲（高达1351 μg/L），远远超过世界卫生组织（世卫组织）地下水砷含量准则的允许极限值，即10 μg/L。由于含水层的地球化学成分和水文流动模式的差异，砷含量分布不均匀。建议利用天然红土吸附作为一种补救策略，以限制砷在地下水中扩散的风险及其对公众健康的影响。

Chemical insecticides are in many cases the only efficient and large-scale method available for pest control. However, insecticidal compounds can have negative impacts on the environment and non-target organisms. Ants, although acting as pests in various crops and environments, provide vital ecosystem services, such as nutrient cycling, predation, and seed dispersal. The impact of bioinsecticides on these insects is frequently overlooked and underreported. This brief review examines key studies on the effects of bioinsecticides on non-target ants, explores hypotheses for the scarcity of research on this topic, and summarizes the important ecological roles of ants.

在许多情况下，化学杀虫剂是唯一有效的大规模害虫控制方法。然而，杀虫化合物会对环境和非目标生物产生负面影响。蚂蚁虽然是各种作物和环境中的害虫，但却提供了重要的生态系统服务，如营养循环、捕食和种子传播。生物杀虫剂对这些昆虫的影响经常被忽视，报道也不足。这篇简短的综述探讨了有关生物杀虫剂对非目标蚂蚁影响的主要研究，探讨了有关该主题研究稀缺的假设，并总结了蚂蚁的重要生态作用。

Health risk assessment of groundwater contamination in the Union Territory of Jammu and Kashmir, northern India 印度北部查谟和克什米尔中央直辖区地下水污染的健康风险评估

IF 6.7 Q1 ENVIRONMENTAL SCIENCES

Current Opinion in Environmental Science and Health

Pub Date : 2024-10-10 DOI: 10.1016/j.coesh.2024.100585

This research underscores the critical problem of contamination of groundwater and its direct consequences on public health in the Union Territory of Jammu and Kashmir, located in the northern India. Groundwater is a vital source of drinking water, with approximately half of the population depending on it. Given its importance, the presence of contaminants in groundwater poses significant risks, necessitating urgent attention and remediation efforts to ensure safe and clean water for communities residing in this region. The main aim of this study is to identify the contaminants in groundwater within the Union Territory of Jammu and Kashmir. Research has shown that several heavy metals, including iron (Fe), lead (Pb), uranium (U), zinc (Zn), manganese (Mn), copper (Cu), mercury (Hg), arsenic (As), radon (Rn), and non-metal ions like fluoride (F) and nitrate (NO₃), are present in groundwater. While the concentrations of some of these elements remain within permissible limits, others, like F, NO₃, U, Rn, and Fe, exceed these limits, posing significant health risks. Health risk assessments indicate that these elevated concentrations of contaminants can adversely affect both humans and animals. Observations also indicate that children are more vulnerable to these contaminants in comparison to adults. Conditions such as cancer and kidney stones have been reported in connection with these contaminants. If these contaminant concentrations continue to rise, there is a risk that the number of cases could increase correspondingly.

这项研究强调了位于印度北部的查谟和克什米尔联邦直辖区地下水污染的严重问题及其对公众健康的直接影响。地下水是重要的饮用水源，约有一半的人口依赖地下水。鉴于其重要性，地下水中污染物的存在构成了重大风险，因此有必要给予紧急关注并开展补救工作，以确保居住在该地区的社区获得安全清洁的饮用水。本研究的主要目的是确定查谟和克什米尔联邦直辖区内地下水中的污染物。研究表明，地下水中存在多种重金属，包括铁 (Fe)、铅 (Pb)、铀 (U)、锌 (Zn)、锰 (Mn)、铜 (Cu)、汞 (Hg)、砷 (As)、氡 (Rn) 以及氟化物 (F) 和硝酸盐 (NO3) 等非金属离子。虽然其中一些元素的浓度仍在允许范围内，但其他元素，如 F、NO3、U、Rn 和 Fe，则超过了这些限制，对健康构成了重大风险。健康风险评估表明，这些污染物浓度的升高会对人类和动物产生不利影响。观察还表明，与成年人相比，儿童更容易受到这些污染物的影响。据报道，癌症和肾结石等疾病都与这些污染物有关。如果这些污染物的浓度继续上升，病例数有可能相应增加。

Research has shown that several heavy metals, including iron (Fe), lead (Pb), uranium (U), zinc (Zn), manganese (Mn), copper (Cu), mercury (Hg), arsenic (As), radon (Rn), and non-metal ions like fluoride (F) and nitrate (NO<sub>3</sub>), are present in groundwater. While the concentrations of some of these elements remain within permissible limits, others, like F, NO<sub>3</sub>, U, Rn, and Fe, exceed these limits, posing significant health risks. Health risk assessments indicate that these elevated concentrations of contaminants can adversely affect both humans and animals. Observations also indicate that children are more vulnerable to these contaminants in comparison to adults. Conditions such as cancer and kidney stones have been reported in connection with these contaminants. If these contaminant concentrations continue to rise, there is a risk that the number of cases could increase correspondingly.</div></div>","PeriodicalId":52296,"journal":{"name":"Current Opinion in Environmental Science and Health","volume":"42 ","pages":"Article 100585"},"PeriodicalIF":6.7,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142719650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
