Moreover, significant positive and negative correlations were observed between biomarkers (triglycerides, thiols, malondialdehyde, glutathione) and trace element concentrations (copper, lead, mercury, nickel, zinc). These findings suggest that the studied biomarkers could be useful for the assessment of oxidative stress in harbour seals exposed to trace elements, but further research with larger sample sizes is needed to better understand their specific associations.</p>","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Preliminary study of oxidative stress biomarkers and trace elements in North Sea harbour seals","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:32:38.806719","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Oxidative stress biomarkers; Harbour seal; Phoca vitulina; Trace elements; Red blood cells; Serum","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-05-19","DateCreate":"2021-05-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000620266400006","VABBcode":null,"OpenAcc":0,"Handle":"10.1016/j.marpolbul.2020.111905"},"refs":null,"anarec":{"AnaID":337347,"PubliDate":2021,"Pagination":"111905","XtraPublOfAnaID":null,"ISBN":null,"Volume":"163","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43520,"SerRR":"Marine Pollution Bulletin.
