The concentrations of most of the studied inorganic contaminants -except mercury and cadmium- were very low. The mercury content of the tissues was high, but in the range of those found in sperm whales previously described in the literature, as shown by Joiris et al. (this volume), and most of the mercury was found under an inorganic form. We found a close correlation between the mercury and selenium contents of the livers, which strongly suggests that the pollutant was detoxified under the tiemannite form, and therefore was not potentially toxic for the animals. On the contrary, cadmium was found in high concentrations, which was expectable owing to the normal diet of the species (cephalopods), but twice those previously described in the literature for sperm whales. Moreover, the metal was not found, as it is generally the case, to be bound to metallothioneins (a protein well known for its protective effect against heavy metals toxicity) and therefore may have contributed to the debilitation of the animals.","AbstractOtherLang":"Negen zware metalen werden geanalyseerd in de lever, spierweefsel en nieren van potvissen die strandden aan de Belgische kust op 18 november 1994. De gehaltes van de meeste onderzochte contaminanten waren laag, behalve van kwik en cadmium. Het kwikgehalte in de weefsels was hoog, maar van dezelfde grootte-orde als deze gevonden in potvissen beschreven in de bestaande literatuur, zoals aangetoond werd door Joiris et al. (dit volume). Het meeste kwik bevond zich bovendien in anorganische vorm. Een sterke correlatie werd gevonden tussen het gehalte aan kwik en selenium in de lever, wat sterk doet vermoeden dat de polluent gedetoxifieerd was onder de tiemanniet-vorm en daardoor niet potentieel toxisch was voor de dieren. Daarentegen werd cadmium gevonden in hoge concentraties, wat enerzijds te verwachten was, gezien het normale dieet van de potvis (inktvissen), maar anderzijds wel twee maal zo hoog was als concentraties beschreven in de literatuur. Meer nog, het metaal bleek niet gebonden aan metallothioninen ( een eiwit dat goed gekend is omwille van zijn beschermende werking tegen toxiciteit van zware metalen) zoals dat gewoonlijk het geval is, en zou daardoor kunnen bijgedragen hebben tot de verzwakking van de dieren.","BibLvlCode":"AS","StandardTitle":"Toxicological investigations on four sperm whales stranded on the Belgian coast: inorganic contaminants","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"sperm whale, heavy metals, detoxification, selenium, cadmium, debilitation","Notes":null,"AnaPub":1997,"MonPub":null,"DateUpdate":"2021-02-23","DateCreate":"2000-08-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":842,"PubliDate":1997,"Pagination":"75-78","XtraPublOfAnaID":null,"ISBN":null,"Volume":"67","Issue":"suppl.","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44202,"SerRR":"Bulletin van het Koninklijk Belgisch Instituut voor Natuurwetenschappen.
