An unknown compound at a retention time close to that of heptachlor epoxide interfered in the determination by electron capture detector-gas chromatography. On a WCOT CP-Sil 7 column programmed from 85 to 175 °C two poorly separated peaks could be detected. Heptachlor epoxide contents up to 1.7 mg/kg (on a fat basis) were obtained, which were about 200 times lower than the PCB levels. The same ratio was also observed in fish from the same area.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Heptachlor epoxide in marine mammals","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:37.036231","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1981,"MonPub":null,"DateUpdate":"2020-11-02","DateCreate":"2009-05-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1981LR94700005","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0048-9697(81)90117-0"},"refs":null,"anarec":{"AnaID":134981,"PubliDate":1981,"Pagination":"41-50","XtraPublOfAnaID":null,"ISBN":null,"Volume":"19","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43780,"SerRR":"Science of the Total Environment.
