Advances in sample pretreatment and detection of PCBs in the environment

Characterization and quantification of microplastics and organic pollutants in mussels by microwave-assisted sample preparation and analytical pyrolysis

“…19 Pyrolysis-based techniques, and in particular pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS), proved to be very powerful tools for the detection and quantication of MPs in different kind of matrices, 20 from marine biota, to sediments and even spider webs. 14,21 In this study we propose an innovative approach based on microwave-assisted pretreatments and Py-GC-MS, to quantify in mussels not only MPs, but also different kind of organic contaminants frequently found in the marine environment like polychlorinated biphenyls (PCBs), [22][23][24] polycyclic aromatic hydrocarbons (PAHs), [24][25][26] phthalates (phthalic acid esters, PAEs), [27][28][29] and a series of compounds commonly dened as contaminants of emerging concerns (CECs). CECs are compounds, such as some pharmaceuticals, pesticides, and UV lters, found in waterbodies that may have a negative impact on the marine ecosystem and on the biota, and are currently under no regulations.…”

Magic extraction: solid-phase extraction and analytical pyrolysis to study polycyclic aromatic hydrocarbon and polychlorinated biphenyls in freshwater

“…Because of their low water solubility, PAHs and PCBs are present in water basins at trace and ultra-trace levels (Wolska et al 1999), which makes their determination challenging. Robust analytical methods have thus been developed to accurately isolate, enrich, and detect them in environmental aqueous matrices (Mwanza et al 2021;Wolska et al 1999;Wu et al 2021).…”
