The TED-GC/MSmethod was applied to investigate a typical European municipal wastewatersystem for possible MP masses. Such investigations are important in view of therecent revision of the Urban WastewaterTreatment Directive. Four differentrepresentative sampling sites were selected: greywater (domestic wastewaterwithout toilet), combined sewer, andinfluent and effluent of a wastewatertreatment plant (WWTP). All samples were collected by fractional filtration.Filtration was carried out over mesh sizes of 500, 100, 50, and in some cases,5 ÎÌm. Polyethylene (PE), polypropylene (PP), and polystyrene (PS) weredetected in all samples, with the PE fraction dominating in all cases. Styrene-butadiene rubber which serves as an indication of tire abrasion, was only foundin the influent of the WWTP. The highest MP mass contents were found in thecombined sewer, so MP can become a source of pollution during heavy rainevents when the capacity limits of the effluent are reached, and the pollutedeffluent is released uncontrolled into the environment. Based on the studies,MP retention from the WWTP could be estimated to be approximately 96%.Few trends in polymer type or mass contents were detected within the differentfractions of the samples or when comparing samples to each other. © 2023 The Authors.Applied Researchpublished by Wiley-VCH GmbH.1 Online-Ressource (10 Seiten)online resourceenghttp://rightsstatements.org/vocab/InC/1.0/MikroplastikpartikelWissenschaftlicher Artikel
