High-resolution mass-spectrometry imaging provides the unique opportunity to obtain two-dimensional information of unlabeled analytes of interest to identify their presence or absence, assess their fate and uptake within biotic and abiotic samples, and visualize the relative changes of endogenous compounds following pollutant exposure. Some researchers have begun demonstrating the power of HR-MSI for environmental applications, although the technique is still new and yet to be fully actualized.

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}

Diffusive gradient in thin-film passive samplers (DGTs) can be deployed in a variety of matrices to accumulate contaminants through diffusion. Due to their simple design, DGTs can be manipulated and adjusted to fit the experimental or monitoring purpose and contaminant of interest. Mercury (Hg) is a ubiquitous trace element of global concern that accumulates in biota and concentrates through the food chain as organic methylmercury.

This is the first comprehensive review of current literature describing the development and environmental deployment of mercury specific DGTs.

Liquid chromatography with tandem mass spectrometry (LC-MS/MS) has traditionally been used to provide targeted quantitation of PFASs in biological samples. The analyte lists covered by targeted LC-MS/MS methods have grown rapidly as more PFASs have been discovered, though not all organofluorine is amenable to this technique. Integrative techniques measuring total organofluorine (TOF) coupled with LC-MS/MS analysis demonstrate that a significant fraction of TOF in biological samples is not captured by LC-MS/MS. This missing organofluorine may be contributed by PFASs that are not amenable to typical PFAS analytical conditions. Here, we review recent progress in quantifying total PFAS burden and identifying the compounds that comprise the unidentified organofluorine fraction (UOF), with a focus on human biological samples. While LC coupled to high-resolution mass spectrometry (LC-HRMS) has identified several novel PFASs in biological samples, these efforts do not appear to fully explain UOF content. Closing the UOF gap will necessitate the development of additional analytical approaches to broaden the chemical space captured by PFAS analysis.
