This review will focus on the selected research papers on nanomaterials as electrochemical, colorimetric and fluorescent sensors for the plant hormones detection from the last twelve years (i.e., 2011 −2023). Nanomaterials integrated analytical techniques (electrochemcial, colorimetric and fluorescence) offer to detect plat hormones with lower detection limits (fM to µM and ng/mL to pg/mL). Importantly, nanomaterials integrated analytical strategies have been successfully detected plant hormones with minimal volumes and sample preparations. The various advantages and limitations of techniques have been also overviewed. The challenges and future perspectives of nanomaterials-based electro- and optical sensors for the analysis of plant hormones are discussed in detail.</span></span></p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47589956","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}

Notable oil spill incidents, such as the Deepwater Horizon, have emphasized the need for molecular-level information on spilled oil to evaluate and monitor environmental damage. In this study, the term 'Environmental Petroleomics' is defined. During the weathering of spilled oil, various effects can alter the oil's chemical composition, including evaporation, dispersion, photo-oxidation, and </span>microbial degradation. The major toxic compounds in the spilled oil are </span>aromatic compounds, followed by polar oxygenated aromatic compounds. Although gas chromatography-mass spectrometry (GC-MS) is an effective approach for compositional analysis of crude oil, it falls short in its ability to separate individual compounds in the weathered oil. This is particularly challenging when dealing with weathered oil enriched with polar oxygen- and sulfur-containing compounds that emerge during the weathering process . Ultra-high-resolution mass spectrometry (UHR-MS) has played a key role in the development of Environmental Petroleomics, proving effective in characterizing various polar species. This review explores the application of ultra-high-resolution mass spectrometry for oil spill research. The study concludes that the toxicity of weathered crude oils results from the photo-oxidation of crude oil molecules into highly oxygenated, water-soluble species. Prospective research in environmental petroleomics concerning the analysis of oil spills may direct its attention towards innovating novel methodologies. These could encompass high-resolution imaging of oil spills, time-resolved analysis of spill dynamics, integration of ultra-high-resolution mass spectrometry (UHR-MS) with complementary techniques, and the utilization of UHR-MS for biomarker analysis.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44856668","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}

Environmental scientists dealing with microplastics employ both field and laboratory blanks to determine the extent of cross-contamination in unknown samples (samples of interest) in their analyses, but this source of uncertainty has yet to be assessed and is being overlooked. This paper intends to present: (1) an overview of the approaches for monitoring external contamination; (2) issues related to unwanted variation or bias introduced into the results; and (3) strategies for improving quality assessment procedures. Our analysis of existing evaluations of blanks in the literature revealed that methods for designing, assessing, and correcting blanks, as well as the expression of results, are likely to be inconsistent. From it, we found that blank data are potentially biased and introduce unwanted variation in unknown sample measurements, which is mostly impacted by the method of sampling, type of matrix material and extraction protocol, approximations in the observation operators used to obtain the data, limitations in characterization, and the correction itself. These findings have broad implications for implementing significant changes in future microplastic investigations, emphasizing the necessity of reducing bias in blank settings as early as the protocol design stage.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45182906","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}
