The aim of this work was to develop and validate a fast and reliable methodology to determine seven VMSs (D3, D4, D5, D6, L3, L4 and L5) in water matrices, based on a small-scale liquid-liquid extraction (LLE) assisted by ultrasounds and using a low volume of organic solvents. VMSs were quantified by gas chromatography-mass spectrometry (GC-MS). This methodology was successfully validated, showing low detection limits and a good precision (most of the relative standard deviations values below 15%) and accuracy (53-108%). Wastewater samples were analyzed and D5 and D6 were the dominant compounds in influent streams, with similar concentrations to those found in literature (up to 7 \u00b5g L-1). Most effluent samples presented VMSs levels below the limits of detection, with only D5 reaching up to 0.05 \u00b5g L-1.<\/jats:p>","DOI":"10.24840\/2183-6493_008.004_0002","type":"journal-article","created":{"date-parts":[[2022,7,8]],"date-time":"2022-07-08T09:29:14Z","timestamp":1657272554000},"page":"2-12","source":"Crossref","is-referenced-by-count":3,"title":["Analysis of Volatile Methylsiloxanes in Water using a Small-scale Liquid-liquid Extraction Method followed by Gas Chromatography-mass Spectrometry (LLE-GC-MS)"],"prefix":"10.24840","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8935-5689","authenticated-orcid":false,"given":"F\u00e1bio","family":"Bernardo","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4102-9606","authenticated-orcid":false,"given":"Nuno","family":"Ratola","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5090-621X","authenticated-orcid":false,"given":"Arminda","family":"Alves","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3955-9042","authenticated-orcid":false,"given":"Vera","family":"Homem","sequence":"additional","affiliation":[]}],"member":"10468","published-online":{"date-parts":[[2022,7,8]]},"container-title":["U.Porto Journal of Engineering"],"original-title":[],"link":[{"URL":"https:\/\/journalengineering.fe.up.pt\/index.php\/upjeng\/article\/download\/2183-6493_008-004_0002\/671","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journalengineering.fe.up.pt\/index.php\/upjeng\/article\/download\/2183-6493_008-004_0002\/671","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,7,8]],"date-time":"2022-07-08T09:29:17Z","timestamp":1657272557000},"score":1,"resource":{"primary":{"URL":"https:\/\/journalengineering.fe.up.pt\/index.php\/upjeng\/article\/view\/2183-6493_008-004_0002"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,7,8]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2022,7,8]]}},"URL":"https:\/\/doi.org\/10.24840\/2183-6493_008.004_0002","relation":{},"ISSN":["2183-6493"],"issn-type":[{"value":"2183-6493","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,7,8]]}}}
