Pharmaceuticals and personal care products (PPCPs) are one of the emerging pollutants (EPs) groups that attracted the environmentalist’s attention according to the increase in their demand. Diclofenac (DFC) is an anti-inflammatory medication used as a first-line treatment for pain. Around 15% of DFC is unmetabolized after human consumption, leading to an increase in the opportunity to release DFC into the environment. DFC may build up in the environment over time, which increases its negative impacts on the ecosystem. Several biological, physical, and chemical techniques have been applied to treat DFC. This review provides an overview of the photodegradation of DFC including photodegradation efficiency, mechanism, the role of physicochemical parameters, and toxicity assessment. Generally, the photodegradation systems showed high efficiency in the removal. However, each experiment has been applied under different experimental conditions and different parameters such as the type and dosage of catalyst, the chosen wavelength of the radiation, pH, temperature, and additive concentration. This led to the differentiation in the photodegradation efficiency and photodegradation rate of DFC. We revealed that the physicochemical parameters of the photocatalytic process are a double edge sword. On the one hand, raising their values up to a certain point might help the treatment work well. On the other hand, a significant rise has a negative impact on the effectiveness of the treatment and raises the expense of the treatment operation. The toxicity tests indicated that most frequent DFC by-products are not safe, and their release into the environment may negatively affect the ecosystem. This review may provide a useful recommendation for future researchers who want to treat DFC by photodegradation and enables them to enhance the applicability of photodegradation.
药品和个人护理产品(PPCPs)是新兴的污染物(EPs)之一,随着其需求量的增加而引起了环保人士的关注。双氯芬酸(DFC)是一种抗炎药物,用于治疗疼痛的一线治疗。大约15%的DFC在人类食用后未被代谢,从而增加了将DFC释放到环境中的机会。随着时间的推移,DFC可能会在环境中积累,从而增加其对生态系统的负面影响。几种生物、物理和化学技术已被应用于处理DFC。本文综述了DFC的光降解研究进展,包括光降解效率、机理、理化参数的作用以及毒性评价。总的来说,光降解系统的去除率很高。然而,每个实验都是在不同的实验条件和不同的参数下进行的,如催化剂的类型和用量、选择的辐射波长、pH、温度和添加剂浓度。这导致了DFC在光降解效率和光降解速率上的差异。我们发现光催化过程的理化参数是一把双刃剑。一方面,将它们的值提高到一定程度可能有助于治疗效果良好。另一方面,大幅上升会对治疗效果产生负面影响,并增加治疗操作的费用。毒性试验表明,最常见的DFC副产品是不安全的,它们释放到环境中可能对生态系统产生负面影响。本文综述可为今后希望通过光降解处理DFC的研究人员提供有益的建议,并使他们能够提高光降解的适用性。

Sildenafil is a brand-name prescription drug that is approved to treat illnesses such as erectile dysfunction (ED). It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. There is a need for increased knowledge on epigenetic environmental toxicological mechanisms of new pollutant sildenafil, its metabolites and its potential environmental health impacts. The scope of the review determines the specific aspects of sildenafil metabolites and the impact of sildenafil on DNA methylation, histone modifications, and non-coding RNA expression. The review expounded that the emerging field of epigenetics has continued to reveal that sildenafil may have an impact beyond its intended purpose of treating erectile dysfunction. Several studies have suggested that sildenafil can alter the epigenetic marks on DNA, potentially leading to changes in gene expression and cellular behavior. Even though the full implications of these epigenetic changes are not yet fully understood, they may have far-reaching effects on human health and development. Further research is needed to fully understand the epigenetic effects of sildenafil and other pharmaceuticals and to develop strategies for mitigating any potential risks. It is crucial to consider the broader implications of drug use and to take a proactive approach to promoting public health and safety.
西地那非是一种品牌处方药,被批准用于治疗勃起功能障碍(ED)等疾病。它属于一类称为磷酸二酯酶5型(PDE5)抑制剂的药物。有必要增加对新污染物西地那非、其代谢物及其潜在环境健康影响的表观遗传环境毒理学机制的了解。综述的范围确定了西地那非代谢物的具体方面,以及西地那非对DNA甲基化、组蛋白修饰和非编码RNA表达的影响。这篇综述阐述了新兴的表观遗传学领域继续揭示西地那非可能有超出其治疗勃起功能障碍的预期目的的影响。几项研究表明,西地那非可以改变DNA上的表观遗传标记,可能导致基因表达和细胞行为的改变。尽管这些表观遗传变化的全部含义尚未完全了解,但它们可能对人类健康和发育产生深远影响。需要进一步的研究来充分了解西地那非和其他药物的表观遗传效应,并制定减轻任何潜在风险的策略。至关重要的是要考虑吸毒的广泛影响,并采取积极主动的办法促进公共健康和安全。

Perfluorooctane sulfonic acid (PFOS) and its salts were listed as persistent organic pollutants (POPs) in the Stockholm Convention to restrict their worldwide usage. PFOS released from dumped solid waste may pose risks to humans and the environment. Great efforts have been made to identify, manage, and dispose of PFOS-containing solid wastes. Herein, we reviewed the relevant literature and regulations to give a complete view of international management practices and treatment technologies for PFOS-containing solid wastes. First, the occurrence and fate of PFOS in solid waste and in the environment, as well as the development of detection methods for PFOS in solid wastes are introduced. Then, relevant regulations from different countries and regions are reviewed and compared. Specific and feasible PFOS control regulations and standards must be developed based on the economic and pollution situations. Traditional disposal technologies such as incineration and landfill are still the mainstream methods for PFOS-containing solid wastes. However, several innovative and promising technologies, including pyrolysis, plasma, cement kiln co-treatment, and smoldering, have raised concern. The disposal efficiency, cost efficiency, and environmental impact of different technologies remain uncertain and deserve greater consideration. In addition, alternative research is briefly introduced. Based on the international experience, prospects for enhancing disposal technology research, preventing secondary pollution during disposal, and proactively developing safe alternatives are made for a summary.
《斯德哥尔摩公约》将全氟辛烷磺酸及其盐类列为持久性有机污染物,以限制其在全世界的使用。倾倒固体废物释放的全氟辛烷磺酸可能对人类和环境构成风险。在查明、管理和处置含全氟辛烷磺酸的固体废物方面作出了巨大努力。本文通过对相关文献和法规的梳理,对含全氟辛烷磺酸固体废物的国际管理实践和处理技术进行了综述。首先介绍了全氟辛烷磺酸在固体废物和环境中的存在和归宿,以及固体废物中全氟辛烷磺酸检测方法的发展。然后,对不同国家和地区的相关法规进行了回顾和比较。必须根据经济和污染情况制定具体可行的全氟辛烷磺酸控制法规和标准。焚烧、填埋等传统处理技术仍是处理含全氟辛烷磺酸固体废物的主流方法。然而,一些创新和有前途的技术,包括热解、等离子体、水泥窑共处理和阴燃,引起了人们的关注。不同技术的处置效率、成本效率和环境影响仍然不确定,值得更多的考虑。此外,还简要介绍了替代研究。根据国际经验,对加强处置技术研究、防止处置过程中的二次污染、积极开发安全替代方案等方面的前景进行了总结。

Pharmaceuticals and personal care products (PPCPs) are receiving abundant attention as emerging contaminants due to their environmental fate and toxicological properties. They include many products with medical, healthcare or specific purposes for humans and/or animals, and exist ubiquitously in our daily lives. After their broad use and consumption, PPCPs are continuously released into earth's environment with pseudo persistent characteristics. More importantly, these pollutants may undergo transformation during environmental geochemistry processes, leading to the formation of transformation products (TPs) that may pose increased risks to human health and ecosystems. Particularly several TPs have been found to be higher concentrations and increased toxic effects as compared to the original PPCPs. Thus, in this critical review, we analyze the literatures on transformation mechanism of PPCPs during the environmental geochemistry processes, including hydrolysis, photochemical transformation, and biodegradation in water systems. The aquatic toxicity and health effects of PPCPs as well as their TPs are emphasized. Furthermore, the current challenges and recommendations for future research are also pointed out. This review will supply helpful information to better understand the behavior of PPCPs in environmental geochemistry processes from the viewpoint of mechanism, catalyzing a more comprehensive research on the risk assessment and management of PPCPs and their TPs in future.
药品和个人护理产品(PPCPs)由于其环境命运和毒理学特性而作为新兴污染物受到广泛关注。它们包括许多用于人类和/或动物的医疗、保健或特定用途的产品,并且在我们的日常生活中无处不在。PPCPs在广泛使用和消费后,以伪持久性特征不断释放到地球环境中。更重要的是,这些污染物可能在环境地球化学过程中发生转化,导致转化产物的形成,可能对人类健康和生态系统构成更大的风险。与最初的ppcp相比,已经发现有几种TPs的浓度更高,毒性作用也更大。因此,本文对PPCPs在水系统中水解、光化学转化和生物降解等环境地球化学过程中的转化机制进行了综述。强调了PPCPs及其tp的水生毒性和健康影响。此外,还指出了目前面临的挑战和对未来研究的建议。本文综述将有助于从机制角度更好地理解PPCPs在环境地球化学过程中的行为,促进未来对PPCPs及其TPs的风险评估和管理进行更全面的研究。

Environmental Carriers for Metal Nanoparticles: Transport, Fate, and Eco-risks 金属纳米颗粒的环境载体:运输、命运和生态风险

The occurrence of metal nanoparticles (MNPs) is an established environmental menace. After MNPs are released into the environment, they can interact with surrounding components and further be embedded within environmental substances, forming MNPs-carrier composites. Many studies have documented MNPs as individual particles. Yet, the specific impacts of environmental substances on the transport, fate, and eco-risks of MNPs-carrier composites have not been systematically analyzed. Here, we conducted a comprehensive review to illustrate the environmental carrier role for MNPs by different environmental substances and components, influencing their occurrence, transport route, transformation, and eco-effect, which calls for a reconsideration of the MNPs’ eco-/health-connectivity. Studies on MNPs’ environmental carrier in primary environmental domains reveal that in the atmosphere, MNPs-carrier composites are from nature-originated particulates followed by anthropogenic sources (e.g., traffic and industry exhausts); in the hydrosphere, various components (e.g., natural organic matter, extracellular polymeric substances, and proteins) can act as major carriers for MNPs; in the biosphere, microorganism and plant tissues can carry MNP-composites, which can be bioaccumulated and biomagnified through trophic transfer. Moreover, MNPs-carrier composites undergo distinct biogeochemical transformations in different environmental components, including aggregation, sedimentation, chemical transformation and dissolution, and the consequential biotransformation. Carriers’ impacts on MNPs’ environmental behavior manifested in changed bioavailability with widespread ecotoxicity via cellular uptake, oxidative stress and metal ions release, as well as in human health with adverse effects. Overall, this review can facilitate the understanding of MNPs-carrier composites’ origin, transformation, fate, and eco-/health risks in the environment, proposing future research needs.
金属纳米颗粒(MNPs)的出现是一种公认的环境威胁。MNPs释放到环境中后,可与周围组分相互作用,并进一步嵌入环境物质中,形成MNPs-载体复合材料。许多研究已经将MNPs记录为单个粒子。然而,环境物质对mnps载体复合材料的迁移、命运和生态风险的具体影响尚未得到系统分析。本文通过对不同环境物质和成分对MNPs发生、迁移路径、转化和生态效应的影响,对MNPs的环境载体作用进行了综述,并提出了对MNPs生态/健康连通性的重新思考。对主要环境域MNPs环境载体的研究表明,在大气中,MNPs载体复合材料主要来自自然来源的颗粒物,其次是人为来源(如交通和工业废气);在水圈中,各种成分(如天然有机物、细胞外聚合物质和蛋白质)可以作为MNPs的主要载体;在生物圈中,微生物和植物组织可以携带mnp复合物,并通过营养转移进行生物积累和生物放大。此外,mnps -载体复合材料在不同的环境组分中经历了不同的生物地球化学转化,包括聚集、沉积、化学转化和溶解,以及随之而来的生物转化。载体对MNPs环境行为的影响表现为通过细胞摄取、氧化应激和金属离子释放改变生物利用度和广泛的生态毒性,并对人体健康产生不良影响。总的来说,本文综述有助于了解mnps载体复合材料的起源、转化、命运和环境中的生态/健康风险,并提出未来的研究需求。

Consequences of Microplastics on Global Ecosystem Structure and Function 微塑料对全球生态系统结构和功能的影响

Microplastics (MPs) are a class of pollutants that can persist for centuries, entering global ecosystems in large amounts. Previous studies have focused on the toxicological effects of MPs on single species or population scales from a narrow ecotoxicological perspective, while the systemic effects of MPs on the structure and function of global terrestrial and aquatic ecosystems are still unknown. In this review, we describe the fate and trophic transfer of MPs in ecosystems, which determines the possible scenarios of their interaction with ecosystems, highlighting the alteration of ecosystem structure and function by MPs. The presence of MPs in ecosystems changes the physicochemical properties of the abiotic environment and the habitat of organisms; these particles then directly or indirectly interact with organisms, leading to toxicological and ecological effects. Importantly, MPs, as a new global pressure, likely affect essential biogeochemical processes such as carbon and nitrogen processes. In addition, MPs affect energy flow by interfering with processes such as energy fixation and transfer in primary producers, energy acquisition, consumption and distribution in consumers, and energy metabolism in decomposers. The effects of MPs on information exchange alter the growth, development, and reproduction of organisms, as well as intraspecific and interspecific relationships. At the same time, as vectors for other global pollutants and pathogens, MPs influence their global transport patterns and pose a significant ecological risk. Early understanding of the toxic costs of MPs from the perspective of ecosystem structure and function is essential to maintain the homeostasis and stability of global ecosystems.
微塑料(MPs)是一类可以持续几个世纪的污染物,大量进入全球生态系统。以往的研究多集中于从狭窄的生态毒理学角度研究MPs对单个物种或种群的毒理学效应,而对全球陆地和水生生态系统结构和功能的系统性影响尚不清楚。在本文中,我们描述了MPs在生态系统中的命运和营养转移,这决定了它们与生态系统相互作用的可能情景,重点介绍了MPs对生态系统结构和功能的改变。MPs在生态系统中的存在改变了非生物环境的物理化学性质和生物体的栖息地;然后,这些颗粒直接或间接地与生物体相互作用,导致毒理学和生态效应。重要的是,MPs作为一种新的全球压力,可能影响基本的生物地球化学过程,如碳和氮过程。此外,MPs通过干扰初级生产者的能量固定和转移、消费者的能量获取、消耗和分配以及分解者的能量代谢等过程来影响能量流。MPs对信息交换的影响改变了生物体的生长、发育和繁殖,以及种内和种间关系。同时,作为其他全球污染物和病原体的载体,MPs影响其全球运输模式,并构成重大生态风险。从生态系统结构和功能的角度及早认识MPs的毒性成本,对于维持全球生态系统的动态平衡和稳定至关重要。

Previous studies have focused on the toxicological effects of MPs on single species or population scales from a narrow ecotoxicological perspective, while the systemic effects of MPs on the structure and function of global terrestrial and aquatic ecosystems are still unknown. In this review, we describe the fate and trophic transfer of MPs in ecosystems, which determines the possible scenarios of their interaction with ecosystems, highlighting the alteration of ecosystem structure and function by MPs. The presence of MPs in ecosystems changes the physicochemical properties of the abiotic environment and the habitat of organisms; these particles then directly or indirectly interact with organisms, leading to toxicological and ecological effects. Importantly, MPs, as a new global pressure, likely affect essential biogeochemical processes such as carbon and nitrogen processes. In addition, MPs affect energy flow by interfering with processes such as energy fixation and transfer in primary producers, energy acquisition, consumption and distribution in consumers, and energy metabolism in decomposers. The effects of MPs on information exchange alter the growth, development, and reproduction of organisms, as well as intraspecific and interspecific relationships. At the same time, as vectors for other global pollutants and pathogens, MPs influence their global transport patterns and pose a significant ecological risk. Early understanding of the toxic costs of MPs from the perspective of ecosystem structure and function is essential to maintain the homeostasis and stability of global ecosystems.","PeriodicalId":21182,"journal":{"name":"Reviews of environmental contamination and toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135980305","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}
