Sewage treatment plants are considered as important pathways for the transfer of perfluoroalkyl and polyfluoroalkyl substances (PFAS) to environment. In conventional wastewater treatment, some these compounds accumulate in sewage sludge via sorption onto suspended solids posing a potential environmental threat during disposal reuse.

Microplastics (MPs) increase global awareness due to their ubiquity, high concentration levels, and devastating effects on the aquatic environment. Wastewater treatment plants (WWTPs) are recognized as a significant source of microplastics in terrestrial environments, particularly for plastics used personal care products textile fibers from clothing industry. The focus present study was determination MP wastewater sewage sludge samples WWTP Ioannina city, according shape, size, concentration, polymer type. A wet peroxide oxidation (WPO) method using 30% H2O2 0.05 M ferrous (II) solution applied water effluent, while an enzymatic digestion combined with WPO employed eliminate organic matter extract MPs samples. Micro-Raman spectroscopy coupled appropriate software detect quantify microplastic particles. outcomes this showed that most representative shape effluent fragments (66.7% 75%, respectively), followed by fibers, spheres, films. Polyamide (PA), p -acrylic acid (PAA), -acrylamide-co-p (PAM-co-PAA) were abundant polymers (100% frequency detection), -vinyl chloride (PVC), -butyl methacrylate (PBMA), -ethylene (PE), -styrene (PS), -propylene (PP), alcohol (PVA), butyral (PVB) (20%-80% detection). mean five sampling campaigns 5.8 ± 0.6 particles/L secondary effluents 33.3 8 particles/g sludge. This focused monitoring campaign, order better understand occurrence, impact, risks associated WWTPs.

Per- and polyfluoroalkyl substances (PFAS) are a diverse group of synthetic chemicals that have gathered significant attention because their persistence in the environment potential health risks. Analytical methods for PFAS detection quantification been developed to address complex nature these compounds various matrices such as water, soil, air, biological samples. This review provides brief yet comprehensive overview separation science utilized analysis, including liquid chromatography (LC), gas (GC), ion (IC), capillary electrophoresis (CE), supercritical fluid (SFC). Additionally, mass spectrometry (MS) techniques, sample preparation methodologies solid-phase extraction (SPE) microextraction (SPME) discussed. Special emphasis is placed on analytical challenges posed by diversity occurrence different environmental contexts. aims provide summary most current techniques applications research, contributing ongoing efforts monitor mitigate contamination.
