These molecules can enter natural biota either in unmetabolized or partially metabolised form and undergoes further transformation depending on biotic and abiotic factors in aqueous and terrestrial ecosystems, which can lead to antimicrobial resistance. This requires timely monitoring and prediction of fluoroquinolone and metabolite changes. The physiochemical flexibility of fluoroquinolones, complicated sampling combinations, and matrix interference in sample preparation and detection could give misleading quantifying results. These complex and massive data sets require rigorous statistical and mathematical data processing approaches to detect analytical fingerprints/patterns, and point - nonpoint source discrimination. This paper has critically reviewed the use of predictive and exploratory chemometric models to identify the patterns and resolve overlapping, asymmetric peaks and multicollinearity fluoroquinolone spectrum data raised from several separative and non-separative detection techniques. Moreover, this review also highlights the crucial parameters involved in determining fluoroquinolones in real-time samples, challenges, and research gaps associated with current analytical techniques. The approach also prioritises the integration of clustering, classification and regression-based chemometrics to achieve justifiable accurate results. This review will address fluoroquinolone detection challenges and help the government and research community to develop better regulatory policies, analytical methods, and mitigation strategies to protect life-saving antibiotics.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":"43 ","pages":"Article e00237"},"PeriodicalIF":11.1,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141638273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic molecularly imprinted polymers (MMIPs) have benefits over traditional molecular imprinted polymers (MIPs) in sample pretreatment because of their larger specific surface areas and highly accessible particular binding sites, which result in excellent specificity and selectivity toward analytes. MMIPs are easily separated from a variety of complicated matrices and have a high adsorption capability. They play an essential role in the efficient extraction of various analytes from a variety of matrices, including water, soil, food and its derivatives, plant extraction, fruits and vegetables, and various biological samples. Additionally, MMIPs have the major benefit of being a green chemistry approach, whether in synthesis or applications; as a result, they effectively reduce pollution in the environment and minimize the use of resources. A variety of MMIP applications from 2019 to 2023 were reviewed in this work. The various approaches and procedures utilized to create MMIPs are covered in this review. In addition, a brief description of several MMIP-based analytical techniques is provided in this manuscript, along with information on various aspects such as their adsorption capacity, equilibrium time, limit of detection, extraction recovery, and recyclability assessment. The types of porogen and functional monomer used have the greatest effect on the efficiency and reusability of the constructed MMIPs. On the contrary, the cross-linker type has no prominent effect on the efficiency and reusability of the constructed MMIPs. Future opportunities and current obstacles to better promote MMIPs features are also covered. This publication served as a comprehensive assessment of a number of analytes in various matrices recovered by MMIP, including pollutants, dyes, natural components, pesticides, herbicides, and insecticides. As a result, it can serve as a guide for creating new MMIP-based analytical techniques for a range of uses.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":"43 ","pages":"Article e00236"},"PeriodicalIF":11.1,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141595180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surface runoff from their widespread use pollutes water and soil. Pesticides deplete beneficial insect populations, upset ecological equilibrium, and contaminate food chains, posing health concerns through bioaccumulation and biomagnification. Moreover, heavy metals from industry, mining, and inappropriate waste disposal are persistent, harmful environmental pollutants. Lead, mercury, cadmium, and arsenic in soils and sediments pollute water supplies and endanger aquatic life, wildlife, and humans. Heavy metal exposure can cause neurological issues, reproductive abnormalities, and cancer, making cleanup necessary. Also, industrial activities, wastewater discharge, and agricultural runoff produce phenolic compounds, another harmful environmental contaminant. Bisphenol A, phenol, and chlorophenols poison aquatic species, limit plant photosynthesis, and alter microbial populations. Additionally, phenolic chemicals can stay in the environment for lengthy durations, causing long-term ecological damage and health concerns from tainted drinking water and food. As a result, environmental monitoring is becoming increasingly important for sensitively detecting and quantifying pesticides, phenolic compounds, and heavy metals. Electrochemical sensors and modification materials are prepared for specific pollutant detection, providing selectivity and sensitivity, thus enabling the detection of the target molecule down to the nanomolar or even picomolar range. In this respect, ordered mesoporous carbon (OMC) materials attract attention in electrochemical sensing applications due to their numerous advantages. OMCs are promising for catalysis and sensing applications due to their well-ordered pore structure, high specific surface area, and tunable pore sizes in the mesopore range. The unique properties of these materials could open a new approach to studying the electrochemical determination of other environmental pollutants. This review covers the properties, advantages, synthesis procedures, and characterization processes of OMCs and focuses on the role of OMCs in the electrochemical detection of environmental pollutants. Moreover, this study examines OMC-based research carried out in recent years in depth.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":"42 ","pages":"Article e00233"},"PeriodicalIF":11.2,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140547396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This importance stems from its well-established role as the primary precursor of potentially harmful disinfection byproducts (DBPs) when subjected to chemical disinfection processes. Characterizing DOM in drinking water is a challenging task due to its inherent heterogeneity and the wide range of organic compounds it contains. Additionally, the composition of DOM can vary based on the source water quality and the specific treatment processes employed. Advanced analytical techniques, such as non-targeted analyses using ultrahigh- or high-resolution mass spectrometry [(U-)HRMS], are improving our understanding of the nature of specific organic compounds present in DOM and their potential to form DBPs. In this review, the most commonly used non-targeted (U-)HRMS approaches for analyzing DOM in raw and treated waters are reported, and their application as a monitoring tool to track changes in DOM and the formation of DBPs in drinking waters is assessed. Moreover, recommendations for achieving a common and comparable DOM fingerprint approach for drinking water among different laboratories and instruments are provided. The non-targeted (U-)HRMS results reviewed here provide DOM indexes and ranges that can assist in tracking the various effects of drinking water treatment processes. Overall, DOM characterization using non-targeted (U-)HRMS is presented as an effective tool for evaluating treatment processes, predicting DBP formation, and the assessment of drinking water quality for human consumption.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":"42 ","pages":"Article e00231"},"PeriodicalIF":11.2,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2214158824000072/pdfft?md5=42a20767263a9cf2cb6049542d5b2465&pid=1-s2.0-S2214158824000072-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140155040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
