C-601 and C-773 are by-products of the aldrin and dieldrin synthesis. Several solvents were compared for the extraction from clay, peat and river sediment. Acetone gave the best results, also after a long period between spiking of soil and sediment samples with organochlorines and extraction. 14 Organochlorines were determined without interference from PCBs. The analysis of heptachlor, aldrin and p·p′-DDT can be interfered with by PCB components. The results of a monitoring program in tributaries of the Rhine River, Western Scheldt and in some harbour basins of Rotterdam are presented. HCB occurred frequently. The most contaminated sediment was found in a harbour basin near a pesticide producing plant. In this sediment the mean concentrations were 0.86 mg kg-1 and 0.18 mg kg<sup>-1</sup> for dieldrin and endrin, respectively, on a dry weight basis.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Determination of organochlorines in river sediment by capillary gas chromatography","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:31:59.635754","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1982,"MonPub":null,"DateUpdate":"2018-01-04","DateCreate":"2018-01-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1982NT13500024","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0043-1354(82)90145-2"},"refs":null,"anarec":{"AnaID":291652,"PubliDate":1982,"Pagination":"1265-1272","XtraPublOfAnaID":null,"ISBN":null,"Volume":"16","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44009,"SerRR":"Water Research.
