The cloud point extraction (CPE) approach has received a lot of interest, and many studies and reviews have already been written on this topic. The CPE is a good separation technique even at ultra-trace analyte levels. The researchers proposed numerous adjustments to make it environmentally friendly, affordable, and precise. Several reviews were handled in conventional CPE, but no analysis was offered that evaluated new CPE procedures based on green solvent-assisted surfactants and evaluated greenness scores. The present study tries to address the observed issue. This overview looks at the clouding phenomena and the applicability of CPE techniques that use green solvents. These approaches involve mixed-micellar media CPE (MM-CPE), ionic liquids CPE (IL-CPE), rapid synergistic CPE based on deep eutectic solvents (RS-DES-CPE), and others. They are simple to apply, efficient, fast, and safe. Also, they are reducing the heating step, chemical amounts, and extraction time compared with the conventional CPE methods. Additionally, the mechanisms and interactions of green solvents and surfactants were discussed. The green solvent selection website and three recent greenness tools have been described, such as Sample Preparation Metric of Sustainability (SPMS), Complex Modified GAPI (ComplexMoGAPI), and Analytical Greenness Metric of Sample Preparation (AGREEprep). Also, a critical comparison was made between the greenness ratings of CPE approaches. In this overview, we present readers with classified descriptions and comparison of CPE forms that with green solvent-assisted surfactants to help them acquire the knowledge they need for future CPE design. In addition, multiple limitations and potential patterns were introduced.

This review article explores several liquid-phase microextraction (LPME) strategies in sample treatment for determining mercury species in several matrices. LPME can be subdivided into four main techniques: dispersive liquid-phase microextraction (DLPME), hollow fiber liquid-phase microextraction (HF-LPME), single drop liquid-phase microextraction (SDME), and cloud point extraction (CPE). The comparative analysis highlights the relative effectiveness of each method. DLPME enables shorter extraction times, but solvent consumption can be high. Although they provide high selectivity, HF-LPME, and SDME, in turn, require longer extraction times, and handling is complex. CPE, employing surfactant-based systems, offers a greener alternative with moderate efficiency but requires careful control of operating conditions. LPME techniques are evaluated in this review, considering advances in green chemistry and the determination and speciation of mercury. The advantages, limitations, and current applications of the techniques are also addressed in the text.

这篇综述文章探讨了几种用于样品处理的液相微萃取（LPME）策略，以测定几种基质中的汞物种。液相微萃取技术可细分为四种主要技术：分散液相微萃取（DLPME）、中空纤维液相微萃取（HF-LPME）、单滴液相微萃取（SDME）和浊点萃取（CPE）。对比分析强调了每种方法的相对有效性。DLPME 可以缩短萃取时间，但溶剂消耗可能较高。HF-LPME 和 SDME 虽然选择性高，但萃取时间长，操作复杂。CPE 采用基于表面活性剂的系统，是一种更环保的替代方法，效率适中，但需要仔细控制操作条件。本综述对 LPME 技术进行了评估，同时考虑了绿色化学以及汞的测定和标示方面的进展。文中还讨论了这些技术的优势、局限性和当前的应用情况。

The concern regarding phthalate ester contamination is a reemerging topic that is not without merit. Since the early 21st century numerous studies have been published on the adverse effects of phthalate exposure. The lack of regulations regarding the presence of phthalates in environmental matrices, however, means that studying their presence in the environment and how that affects ecosystems and human health is an important area of research. The objective of this review is to highlight the issues of phthalate contamination, as well as the different analytical techniques that have been described in the literature to identify phthalate esters in environmental samples.

对邻苯二甲酸酯污染的担忧是一个新出现的话题，它并非毫无道理。自 21 世纪初以来，已经发表了大量关于接触邻苯二甲酸酯的不良影响的研究报告。然而，由于缺乏有关环境基质中邻苯二甲酸酯存在的法规，因此研究邻苯二甲酸酯在环境中的存在及其如何影响生态系统和人类健康是一个重要的研究领域。本综述旨在强调邻苯二甲酸酯污染问题，以及文献中描述的用于识别环境样本中邻苯二甲酸酯的不同分析技术。

Microplastics and nanoplastics (MPs/NPs) are a growing environmental concern owing to their widespread distribution and potential adverse effects on ecosystems and human health. Numerous studies on MPs/NPs have focused on their distribution, behavior, and fate; however, there is a lack of knowledge regarding these materials in groundwater, a primary source of drinking water. This is attributed to the difficulties in conducting such studies, the absence of universally accepted standard procedures, and the absence of a global consensus on efficient and accurate analytical protocols. These factors hinder direct data comparison and evaluation. This review provides a summary of the sources of MPs/NPs and their worldwide distribution in groundwater, and categorizes the analytical methods employed for their characterization, including sampling and pretreatment procedures. Finally, promising new technologies for the detection and characterization of MPs/NPs are discussed.

由于微塑料和纳米塑料（MPs/NPs）的广泛分布以及对生态系统和人类健康的潜在不利影响，它们正日益成为环境问题。有关 MPs/NPs 的大量研究都集中在它们的分布、行为和归宿上；然而，人们对作为饮用水主要来源的地下水中的这些材料还缺乏了解。这归因于开展此类研究的困难、缺乏普遍接受的标准程序，以及对高效、准确的分析协议缺乏全球共识。这些因素阻碍了数据的直接比较和评估。本综述概述了 MPs/NPs 的来源及其在地下水中的全球分布情况，并对表征 MPs/NPs 所采用的分析方法进行了分类，包括采样和预处理程序。最后，还讨论了用于检测和表征 MPs/NPs 的前景看好的新技术。

The European Union requires environmental monitoring to identify potential pollutants suspected of causing adverse effects, affecting not only aquatic organisms but also posing direct and negatively influence to human health. Comprehensive knowledge about their occurrence and impact of these pollutants in environmental matrices, including microplastics, is essential for informed decision regarding their inclusion in surveillance lists. This study focuses on reviewing and assessing the analytical methodologies employed in determine substances listed in the last 4th European Watch List, in various environmental matrices, including water, soils, biota, and microplastics. Additionally, the different interaction mechanisms of adsorption onto microplastics are discussed. A dedicated section is also addressed to examine the occurrence of these substances in diverse environmental matrices. The findings contribute to a better understanding of the presence and effects of these substances, aiding in the development of effective surveillance strategies to mitigate their impact on the environment.

The co-occurrence of pharmaceutical residues and micro(nano)plastics in aquatic environments raises concerns about their potential interactions and consequent fate, transport, bioavailability, and toxicity. While numerous studies have investigated these interactions under laboratory conditions, a significant knowledge gap remains regarding their behaviour in real-world scenarios. This review addresses this gap by critically analysing recent literature on pharmaceutical sorption to micro(nano)plastics in environmental samples or under simulated natural conditions. Key findings underscore the nature of these interactions, influenced by factors such as microplastics’ type, surface area, and biofouling. However, the scarcity of field studies and persistent analytical challenges (including sampling, extraction, and detection limitations), hinder a comprehensive understanding of these processes in real scenarios. Future efforts should prioritise the development of standardised methodologies, advanced analytical techniques, and expanded field-based monitoring to comprehensively assess the environmental and human health risks associated with pharmaceutical-microplastic interactions. This knowledge is crucial for informing effective mitigation strategies and policy decisions to address the growing concern of pharmaceutical and microplastic pollution in aquatic ecosystems.

药物残留和微（纳米）塑料同时出现在水生环境中，引起了人们对它们之间潜在的相互作用以及随之而来的归宿、迁移、生物利用率和毒性的关注。虽然已有大量研究对实验室条件下的这些相互作用进行了调查，但关于它们在现实世界中的行为，仍然存在着巨大的知识差距。本综述通过批判性地分析环境样本或模拟自然条件下药物对微（纳）塑料吸附的最新文献，弥补了这一空白。主要研究结果强调了这些相互作用的性质，它们受到微塑料类型、表面积和生物污垢等因素的影响。然而，实地研究的稀缺性和持续存在的分析难题（包括取样、提取和检测限制）阻碍了对真实场景中这些过程的全面了解。未来的工作应优先发展标准化方法、先进分析技术和扩大实地监测，以全面评估与药物-微塑料相互作用相关的环境和人类健康风险。这些知识对于制定有效的缓解战略和政策决定，解决水生生态系统中日益严重的药物和微塑料污染问题至关重要。

The rapid industrialization and urbanization of recent decades have intensified the global challenge of heavy metal pollution, necessitating the development of advanced sensing technologies for efficient detection and monitoring. Multiplexed detection, seeking either the simultaneous assessment of multiple analytes in the same experiment or the multi-detection of a single analyte in a complex sample matrix replete of interfering species, has gained, in recent years, a noteworthy interest amidst the analytical community. Evolving from early conventional techniques, multiplexed detection has been able, to deliver reliable and efficient analysis in fields as different as clinical, pharmaceutical, food and environmental analysis. The research on nanomaterials, in particular on photoluminescent quantum dots (QDs), has paved the way for the implementation of innovative and flexible multiplexed assays since their remarkable optical properties and tailored reactivity could be arranged in many configurations, combining different fluorophores and molecular recognition elements and providing the means for the establishment of definite reaction pathways and detection methods. From this particular study it concludes that, the development of QDs -based multiplexed detection techniques, examine the distinct roles they could play at the sensing platform, either alone or combined with other materials, and discuss the emerging developments and trends of QDs based nanosensors for the real-time detection of heavy metal ions. A quest of recent advances, actual issues, and potential futures of QDs-based nanosensors for heavy metals monitoring are provided in this study.

近几十年来，快速的工业化和城市化加剧了重金属污染这一全球性挑战，因此有必要开发先进的传感技术，以实现高效的检测和监测。近年来，多重检测技术受到了分析界的广泛关注，它既可以在同一实验中同时评估多种分析物，也可以在充满干扰物的复杂样品基质中对单一分析物进行多重检测。从早期的传统技术发展而来的多重检测技术已经能够在临床、制药、食品和环境分析等不同领域提供可靠而高效的分析。对纳米材料，特别是光致发光量子点（QDs）的研究为实施创新、灵活的多路复用检测铺平了道路，因为它们具有显著的光学特性和定制的反应活性，可以进行多种配置，结合不同的荧光团和分子识别元素，为建立明确的反应途径和检测方法提供了手段。本研究总结了基于 QDs 的多路复用检测技术的发展，考察了它们在传感平台上单独或与其他材料结合所能发挥的独特作用，并讨论了基于 QDs 的纳米传感器在重金属离子实时检测方面的新兴发展和趋势。本研究对基于 QDs 的重金属监测纳米传感器的最新进展、实际问题和潜在前景进行了探索。

The enormous structural complexity of millions of per- and polyfluorinated alkyl substances (PFASs) poses a major challenge for their chemical analysis. One approach to partially address this challenge is the so-called total oxidizable precursor (TOP) assay. In the past years, however, different laboratories worldwide modified the method in multiple ways leading to a confusingly complex variety of TOP assay approaches. This review aims to provide an overview on this methodological complexity and to identify key parameters and their potential influence on the results and method interpretation. Parameters of all available studies were summarized in a complex table. The amount and concentration of oxidation reagents, the reaction time, temperature and pH value during oxidation, the time of internal standard addition, and the suite of analyzed oxidation products were identified as key factors affecting oxidation efficiency, nature of reaction products, and completeness of precursor assessment. The current complexity of TOP assay approaches demonstrates the need for further method harmonization and standardization, which should include measures to ensure and assess the completeness of precursor oxidation. A further understanding of the chemical reactions during the TOP assay and the inclusion of additional oxidation endpoints were identified as research needs for the future. This review article paves the way for the further implementation of the TOP assay as an important tool to assess the world of PFAS more comprehensively, thereby supporting environmental monitoring, assessment of PFAS contaminations, and the success control of designated PFAS regulations.

数百万全氟和多氟烷基物质（PFASs）的结构非常复杂，这给其化学分析带来了巨大挑战。部分应对这一挑战的方法之一是所谓的总可氧化前体（TOP）测定法。然而，在过去的几年中，全球不同的实验室以多种方式对该方法进行了修改，从而导致了令人困惑的各种 TOP 分析方法。本综述旨在概述这种方法的复杂性，并确定关键参数及其对结果和方法解释的潜在影响。所有可用研究的参数都汇总在一个复杂的表格中。氧化试剂的用量和浓度、反应时间、氧化过程中的温度和 pH 值、内标添加时间以及所分析的氧化产物的种类被确定为影响氧化效率、反应产物性质和前体评估完整性的关键因素。目前 TOP 检测方法的复杂性表明需要进一步协调和标准化方法，其中应包括确保和评估前体氧化完整性的措施。进一步了解 TOP 检测过程中的化学反应以及纳入更多氧化终点被确定为未来的研究需求。这篇综述文章为进一步实施 TOP 分析法铺平了道路，使其成为更全面地评估 PFAS 世界的重要工具，从而为环境监测、PFAS 污染评估和指定 PFAS 法规的成功控制提供支持。

The hyphenation of ion mobility separation (IMS) with high-resolution mass spectrometry (HRMS) presents a milestone in the screening of organic micropollutants (OMPs) in complex environmental matrices. Its use has become progressively more widespread in environmental analysis and has led to the development of novel analytical strategies. This work provides a comprehensive overview of the advantages of using IMS-HRMS instrumentation, with a special focus on environmental screening studies. IMS provides an additional parameter for OMP identification, a reduction of spectral background noise and the power to resolve isomeric/isobaric coeluting interferences. These advantages lead to a reduction of false positive identifications. By describing the fundamentals and rationale behind the observed advancements, we highlight areas for further development that will unlock new potential of IMS-HRMS. For example, an enhanced availability of empirical IMS data following the FAIR principles, a better standardization of IMS-HRMS data processing workflows and a higher IMS resolving power are possible ways to advance the use of IMS-HRMS instruments for the analysis of complex environmental samples.
