Mounting global water scarcity, environmental degradation, and a lack of centralized wastewater management infrastructure in widespread and remote areas of developing countries invite innovative and sustainable approaches for on-site wastewater management. To address the above concern, a bioelectrochemically assisted on-site toilet waste treatment stands out as a cutting-edge and innovative technology, uniquely capable of addressing the intricate issues posed by poor on-site wastewater management. A “Bioelectric Toilet” treats human wastewater on-site using microbial fuel cells (MFCs)-based system while simultaneously harvesting bioelectricity. Further, under anaerobic conditions, this system converts the organic substrate to carbon dioxide instead of methane, ammonia to nitrogen, and sulphide to elemental sulfur, providing a convincing avenue for attaining global environment-friendly sanitation and sustainability goals, at the same time avoiding odor problem. This review explores the design concept, operational mechanism, and implications of Bioelectric Toilets. Furthermore, it assesses the potential benefits, obstacles, and future possibilities of widespread adoption of Bioelectric Toilets in various socioeconomic circumstances.

日益严重的全球水资源短缺、环境退化以及发展中国家广泛和偏远地区缺乏集中的废水管理基础设施，需要采用创新和可持续的方法进行现场废水管理。为了解决上述问题，生物电化学辅助现场厕所废物处理作为一项尖端和创新技术脱颖而出，能够独特地解决现场废水管理不善所带来的复杂问题。“生物电厕所”利用微生物燃料电池（mfc）系统现场处理人类废水，同时收集生物电。此外，在厌氧条件下，该系统将有机底物转化为二氧化碳而不是甲烷，将氨转化为氮，将硫化物转化为单质硫，为实现全球环境友好型卫生和可持续发展目标提供了令人信服的途径，同时避免了气味问题。本文探讨了生物电厕所的设计理念、运行机制及其意义。此外，它还评估了在各种社会经济环境下广泛采用生物电厕所的潜在好处、障碍和未来可能性。

In many countries, governments are emphasizing the development of smart cities to establish economic growth and provide a quality of life to the inhabitants. Reutilization of wastewater after treatment can prevent water scarcity in smart cities. However, the presence of emerging contaminants (ECs) in wastewater poses serious health concerns. Traditional contaminant removal technologies have high operational costs, energy and carbon-intensive natures, and the generation of non-biodegradable and hazardous byproducts. In this context, microbial enzymes promise to provide a sustainable and low-cost approach for the removal of ECs. Various microbial enzymes, such as laccase, tyrosinase, amylase, lipase, etc., are being studied for ECs’ removal from wastewater. This review will discuss the concept of water management strategies in smart cities. Furthermore, the review emphasizes the issue of ECs in treated wastewater and the benefits of utilizing microbial enzymes for efficient EC removal. The review further discusses the Sustainable Development Goals (SDGs) related to enzymatic water treatment.

在许多国家，政府都在强调智能城市的发展，以建立经济增长并为居民提供高质量的生活。废水处理后的再利用可以防止智慧城市的水资源短缺。然而，废水中新兴污染物（ECs）的存在引起了严重的健康问题。传统的污染物去除技术具有操作成本高、能源和碳密集的特点，并且产生不可生物降解的有害副产品。在这种情况下，微生物酶有望提供一种可持续和低成本的方法来去除ECs。研究了漆酶、酪氨酸酶、淀粉酶、脂肪酶等微生物酶对废水中ECs的去除作用。本文将讨论智慧城市水管理战略的概念。此外，综述强调了处理废水中EC的问题以及利用微生物酶高效去除EC的好处。本文进一步讨论了与酶法水处理相关的可持续发展目标（SDGs）。

This paper offers a comprehensive examination of the global footprint of pesticides consumption, revealing the disproportionate usage in high-income countries and highlighting the severe environmental and health risks posed by chemicals such as organochlorines and organophosphates. While numerous studies have been conducted on assessing the fate and transport of pesticides in the natural environment in developed nations, however, there is pressing need for similar research in developing regions, within South-East Asia, Latin America, and the African Union. Due to the cumulative nature of pesticides and the duration of exposure, it was expected that biota would show higher average, minimum, and maximum concentrations, along with increased variability. Water appears to be slightly more contaminated than sediment, but the most concerning revelation is the prevalence of pesticides in the air. Emphasizing the urgency of sustainable practices, the paper proposes microcosmic understanding on the degradation of pesticides, their contribution to antimicrobial resistance, and the development of environmentally friendly alternatives.

本文全面考察了农药消费的全球足迹，揭示了高收入国家不成比例的使用情况，并强调了有机氯和有机磷等化学品造成的严重环境和健康风险。虽然已经进行了许多关于评估发达国家自然环境中农药的命运和运输的研究，但是，迫切需要在东南亚、拉丁美洲和非洲联盟的发展中地区进行类似的研究。由于农药的累积性质和暴露时间，预计生物群将显示更高的平均、最低和最高浓度，同时变异性也会增加。水的污染程度似乎比沉积物稍高，但最令人担忧的是空气中农药的普遍存在。强调可持续实践的紧迫性，本文提出了对农药降解的微观认识，它们对抗菌素耐药性的贡献，以及开发环境友好的替代品。

Agricultural intensification harms biodiversity and contributes to climate change and ecosystem services (ES) degradation. Therefore, this opinion study aims to assess the impacts of agricultural intensification in three key aspects. Agricultural intensification causes biodiversity loss, greenhouse gas emissions, climate change, and an increase in the severity and frequency of extreme events. This will negatively impact all regulating and cultural ES (except for knowledge systems) and all provisioning ES in the long term. Sustainable agriculture practices are not enough to ensure food security in a world with a growing demand for food. Ensuring food security without compromising the environment is one of the greatest challenges of our time. Although it is necessary to ensure food security, without healthy ecosystems, this is not possible. A transformational change in our society and policy is needed to halt this process. Therefore, it is essential to recognise that a shift in consumption habits is necessary.

农业集约化危害生物多样性，并导致气候变化和生态系统服务（ES）退化。因此，本意见研究旨在从三个关键方面评估农业集约化的影响。农业集约化导致生物多样性丧失、温室气体排放、气候变化以及极端事件的严重程度和频率增加。从长远来看，这将对所有监管和文化环境服务（知识系统除外）以及所有提供环境服务产生负面影响。在一个粮食需求不断增长的世界，可持续农业做法不足以确保粮食安全。在不损害环境的情况下确保粮食安全是我们这个时代面临的最大挑战之一。虽然确保粮食安全是必要的，但没有健康的生态系统，这是不可能的。我们的社会和政策需要进行转型变革，以阻止这一进程。因此，有必要认识到，消费习惯的转变是必要的。

This review summarizes recent reports related to fate and transport of antibiotics, degradation pathways in agricultural environments, and human and environmental health and ecotoxicity concerns related to environmental exposures. Studies utilizing wide-ranging designs to monitor or simulate agroecosystems exposed to antibiotics were reviewed to better understand the impacts of antibiotic compounds in various environmental matrices (soil, water, and plant biomass). Based on these recent reports, antibiotic compounds enter and persist in agricultural environments in environmentally relevant amounts. These biologically active compounds have the potential to impact natural biological populations, namely microbial populations that facilitate ecosystem services and plant systems that have the capacity to uptake antibiotic compounds into plant tissue (roots, stems, leaves, etc.). Studies focusing on plant storage of antibiotics consistently noted storage is observed to be preferential to below-ground/-surface storage (roots) rather than in above-ground/-surface (stems, shoots, leaves, and seeds).

本文综述了最近有关抗生素的命运和运输、农业环境中的降解途径以及与环境暴露有关的人类和环境健康和生态毒性问题的报道。本文回顾了利用广泛设计来监测或模拟暴露于抗生素的农业生态系统的研究，以更好地了解抗生素化合物在各种环境基质（土壤、水和植物生物量）中的影响。根据这些最近的报告，抗生素化合物以与环境相关的数量进入并持续存在于农业环境中。这些生物活性化合物有可能影响自然生物种群，即促进生态系统服务的微生物种群和有能力将抗生素化合物吸收到植物组织（根、茎、叶等）的植物系统。关注抗生素植物储存的研究一致指出，观察到的储存优先于地下/地表（根）而不是地上/地表（茎、芽、叶和种子）。

Emerging contaminants (ECs) in water represent a significant environmental and public health challenge, with compounds such as pharmaceuticals, pesticides, and endocrine disruptors posing substantial risks. In Mexico, the detection of ECs has intensified, particularly during the COVID-19 pandemic, due to increased pharmaceutical consumption. This review highlights the most frequently detected ECs, including naproxen, carbamazepine, 17-β estradiol, Bisphenol A, and triclosan, which are prioritized for regulation based on their high concentrations and adverse effects on both aquatic ecosystems and human health. Despite Mexico's efforts to monitor these contaminants, the country faces significant challenges in terms of regulation and removal. Conventional wastewater treatment methods are insufficient to eliminate ECs, requiring the implementation of advanced technologies such as advanced oxidation processes. However, a lack of political intervention, inadequate regulatory frameworks, and limited public awareness hinder progress. This review underscores the need for stronger governmental action, interdisciplinary collaboration, and public education to mitigate EC pollution. The development of new regulations and the integration of advanced treatment technologies into existing infrastructure are crucial to preventing long-term environmental damage and safeguarding public health. Additionally, promoting awareness among consumers about the risks of ECs could lead to more sustainable product choices and reduce contamination of water sources.

水中新出现的污染物（ECs）对环境和公共卫生构成重大挑战，药物、农药和内分泌干扰物等化合物构成重大风险。在墨西哥，由于药品消费量增加，特别是在COVID-19大流行期间，ECs的发现有所加强。本文综述了最常检测到的ECs，包括萘普生、卡马西平、17-β雌二醇、双酚A和三氯生，基于它们的高浓度和对水生生态系统和人类健康的不利影响，优先进行调控。尽管墨西哥努力监测这些污染物，但该国在监管和清除方面面临着重大挑战。传统的废水处理方法不足以消除ec，需要采用先进的技术，如高级氧化工艺。然而，缺乏政治干预、监管框架不足和公众意识有限阻碍了进展。这一综述强调了加强政府行动、跨学科合作和公众教育以减轻EC污染的必要性。制定新法规和将先进处理技术纳入现有基础设施，对于防止长期环境破坏和保障公众健康至关重要。此外，提高消费者对ECs风险的认识可能会导致更可持续的产品选择，并减少水源污染。

With the rising global burden of allergies and asthma, bioaerosols have gained the attention of physicians and researchers over the past decades. However, bioaerosols still remain underestimated, excluded from EU Directives. This work points out that respiratory diseases, an emerging human health risk, may be predicted and appropriately managed only if the entirety of co- and multi-exposures, biogenic as well as mixed (chemical-biological) is considered, especially for vulnerable population groups. Here we present an overview of the state of the art in bioaerosol research and its challenges, and pinpoint unmet research and policy needs in a rapidly changing world.

随着全球过敏和哮喘负担的增加，生物气溶胶在过去几十年里引起了医生和研究人员的注意。然而，生物气溶胶仍然被低估，被排除在欧盟指令之外。这项工作指出，呼吸道疾病是一种新出现的人类健康风险，只有考虑到共同和多重暴露的全部情况，包括生物和混合（化学-生物）暴露，才能预测和适当管理，特别是对弱势群体而言。在这里，我们概述了生物气溶胶研究的现状及其挑战，并指出在快速变化的世界中未满足的研究和政策需求。

Effects of microplastics on water disinfection and formation of disinfection by-products 微塑料对水消毒及消毒副产物形成的影响

The presence of microplastics (MPs) in water systems has emerged as a significant concern due to their persistence, ubiquity, and potential to interfere with treatment processes. While some studies have investigated the interactions of MPs with disinfectants and MPs’ potential to act as precursors for disinfection by-products (DBPs), most have relied on laboratory setups that employ unrealistically high concentrations of MPs and disinfectants doses. These conditions fail to replicate the complex effects of background chemistry, the presence of microbial communities, and other aspects of environmental dynamics typical of actual water treatment plants (WTPs) and wastewater treatment plants (WWTPs). The results from such studies cannot be used to unambiguously understand and predict the real-world scenarios of MP effects, thereby limiting real-world applicability of the model experiments. Another aspect of MP-associated effects is their role as carriers for pathogens, antibiotic-resistant genes (ARGs), and disinfectant-resistant genes (DRGs), along with their capacity to interfere with disinfection efficacy while forming a potential habitat for microbial communities. The study calls for a paradigm shift towards more realistic field-representative studies that are needed to bridge the gap between lab and field results and ultimately accurately assess the risks that MPs pose in water treatment contexts.

微塑料（MPs）在水系统中的存在已成为一个重大问题，因为它们的持久性，普遍性和潜在的干扰处理过程。虽然一些研究调查了MPs与消毒剂的相互作用以及MPs作为消毒副产物（DBPs）前体的潜力，但大多数研究依赖于使用不切实际的高浓度MPs和消毒剂剂量的实验室设置。这些条件无法复制背景化学，微生物群落的存在以及实际水处理厂（WTPs）和废水处理厂（WWTPs）典型的环境动力学的其他方面的复杂影响。这些研究的结果不能用于明确地理解和预测MP效应的实际情况，从而限制了模型实验的实际适用性。mp相关效应的另一个方面是它们作为病原体、抗生素耐药基因（ARGs）和消毒剂耐药基因（DRGs）的载体，以及它们在为微生物群落形成潜在栖息地的同时干扰消毒效果的能力。该研究呼吁将范式转向更现实的实地代表性研究，以弥合实验室和实地结果之间的差距，并最终准确评估MPs在水处理环境中造成的风险。
