In 1988 treedt een trendbreuk op in de waterkwaliteit. Vanaf dat jaar dalen de concentraties van een aantal stoffen. Deze verbetering doet zich vooral voor in de Westerschelde en in de Schelde stroomafwaarts van Antwerpen.","BibLvlCode":"MS","StandardTitle":"Ontwikkeling in de belasting en de waterkwaliteit van het Schelde-estuarium in de periode 1980 - 1991","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":1992,"DateUpdate":"2012-10-08","DateCreate":"2006-09-13","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":null,"monrec":{"MonID":103546,"ISBN":null,"PubliDate":1992,"IssueDate":null,"Volume":"92.042","Issue":null,"Pagination":"94 + bijlage","Place":"Middelburg","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":61899,"SerRR":"DGW Rapport.
