Target VOCs were selected from lists of priority pollutants to the North Sea, and included chlorinated short-chain hydrocarbons (CHCs), monocyclic aromatic hydrocarbons (MAHs) and chlorinated monocyclic aromatic hydrocarbons (CMAHs). Samples were taken between Vlissingen and Temse over a 95 km trajectory, and analysed by purge-and-trap and high resolution gas chromatography-mass spectrometry. Data were attended by analyses deemed ‘in control’ by a rigorous quality assurance/quality control program, as proposed by Quality Assurance of Information for Marine Environmental Monitoring in Europe (QUASIMEME). CHCs were among the most commonly found VOCs in the estuary, ranging from a few ng l<sup>-1</sup> to several µg l<sup>-1</sup>. Most analytes were traceable to a single input source in the upper part of the estuary, which is densely populated and highly industrialized. By contrast, the occurrence of MAHs resulted from contributions of a wide spectrum of sources. The CMAHs were less abundant in the water column, and were mainly detected as chlorobenzene and 1,4-dichlorobenzene. Concentrations of several priority VOCs have markedly decreased since 1995 owing to emission reduction efforts within international frameworks for the protection of the North Sea.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Spatial and temporal variability of priority volatile organic compounds in the Scheldt estuary","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-20 01:31:57.324139","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"    Volatile organic compounds;     Scheldt estuary;     Chlorinated short-chain hydrocarbons;     Monocyclic aromatic hydrocarbons;     Chlorinated monocyclic aromatic hydrocarbons;     Spatial variability;     Temporal variability","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2015-11-04","DateCreate":"2013-01-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000223414000012","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.watres.2004.04.022"},"refs":null,"anarec":{"AnaID":221725,"PubliDate":2004,"Pagination":"3241-3250","XtraPublOfAnaID":null,"ISBN":null,"Volume":"38","Issue":"14-15","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44009,"SerRR":"Water Research.
