This critical global ecosystem faces unprecedented pressures from human impacts. Pollution stemming from plastic debris, oil spills, industrial effluent, and agricultural runoff degrades marine ecosystems, compromises biodiversity, and poses significant risks to human well-being. Effective and timely monitoring is crucial for mitigating these threats. Microfluidic technology, through its precise control and manipulation of fluids at the microscale, facilitates rapid and sensitive analysis of diverse oceanographic parameters. This technology offers significant advantages for ocean monitoring, enabling miniaturization of analytical systems, cost reduction, and deployment in remote or challenging environments. This review comprehensively summarizes recent advancements in microfluidic chip technology for marine environmental monitoring, encompassing water quality analysis (dissolved oxygen, pH, nutrients); pollutant detection (oil, heavy metals, persistent organic pollutants); emerging contaminant monitoring (microplastics, pharmaceuticals); and climate-related research (ocean acidification, aerosol phase behavior, ice nucleating particles). We discuss current challenges, including the need for robust, low-power devices for long-term in situ deployment, and outline the future potential of this transformative technology in marine environmental protection.

This review looks at various analytical techniques for total petroleum hydrocarbons determination, such as gas chromatography with different detection methods, infrared based and fluorescence spectroscopic methods, in addition to gravimetric analysis. Green Analytical Procedure Index was used to investigate the environmental impact of the techniques along with different coupled extraction methods. Green Analytical Procedure Index individually evaluates the sample preparation, the type of instrumental technique, the reagents and solvents employed, the health and safety hazard, occupational hazard, and waste of each proposed analytical tool. This literature review showed that Soxhlet extraction, although ranked lower in greenness, is still one of the most widely used techniques for total petroleum hydrocarbons determination due to its completeness. Techniques like gas chromatography - mass spectrometer coupled with solid-phase microextraction, and infrared based tools with direct application are greener because the use of solvent is negligible, and the preparation of the sample is minimal. At the same time infrared based techniques showed lower prediction accuracy compared to gas chromatography - mass spectrometer coupled with solid-phase microextraction. This review highlights the critical need to balance analytical performance with environmental sustainability, offering insights into future developments in forensic and environmental monitoring. It shows pathways toward increasing the greenness of widely used techniques and future use in forensic investigations and environmental monitoring. Overall, this review is among the first to systematically assess total petroleum hydrocarbons analytical methods using Green Analytical Procedure Index, bridging the gap between analytical efficiency and green chemistry principles.</div></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":"46 ","pages":"Article e00262"},"PeriodicalIF":11.1,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746805","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}

Currently, PCR based assays are frequently used methods for the detection of viral illnesses further allowing the precise diagnosis of various diseases but these techniques still suffer several limitations including long time to get results and the need for experts to run. As alternative approaches, low-cost nanobiosensors are rapid and trustworthy diagnostic systems for point-of-care diagnosis because of their high sensitivity and selectivity.

However, due to the low concentration of pesticides and the complexity of the entire sample, it is essential to use sample preparation approaches before determining pesticides. Among sample preparation approaches, micro-solid-phase extraction (µ-SPE), as a miniaturized extraction technique, has garnered much attention. This technique decreases the use of materials, reagents, and solvents. Additionally, µ-SPE applies micro- and/or nano-based sorbents and employs miniaturized extraction gadgets and devices. The attributes of µ-SPE, plus the concepts of green analytical chemistry, have encouraged analytical scientists to introduce and use green and environmentally friendly materials in µ-SPE techniques. Chitosan (CS) is a biocompatible, low- or negligible-toxic, environmentally friendly, and cost-effective material. Another valuable property of CS is its capability for modification and combination with different compounds. CS-based materials not only address the problems of traditional sorbents but also introduce new ones with excellent features such as high stability, high adsorption capacity, etc. These factors motivated us to assess the recent development in using CS-based sorbents for the µ-SPE of pesticides from 2016 to 2025. In this article, the properties of CS are illustrated. Different CS composites and the possible mechanisms for extracting pesticides are reviewed. Finally, the current trends and prospects related to using CS-based sorbents in the µ-SPE of pesticides are summarized.
