Mass spectrometry (MS) has been crucial for the detection of fraudulent activities in VOO, mainly related to the verification of geographical origin or cultivar variety, the correct discrimination between different commercial categories, and adulteration with other vegetable oils or lower-quality olive oils. An ample range of MS approaches have been reported, including chromatographic systems coupled to MS, direct MS using different ionization sources, analysis with minor or even no sample preparation by ambient MS methods, and MS-based elemental analysis techniques.

Detailed examinations of their distinctive interactions within various aquatic ecosystems are also presented. While MP are commonly toxic to most microorganisms, they could also enrich specific microbial groups such as pathogens and hydrocarbon-degrading bacteria due to the chemotaxis and easier nutrition access of microorganisms. On the other hand, microorganisms are capable of secreting extracellular enzymes that biodegrade MPs into oligomers, dimers, and monomers, hereby changing the density, crystallinity, and surface roughness of MPs, consequently influencing the MP distribution patterns in aquatic environments.

This review critically analyzes the principal methodologies that associate DIC with these techniques, comparing the effectiveness of different approaches and their applications. Crucial factors such as accurate calibration and lighting control are discussed as they can significantly impact the accuracy of DIC measurements.
