To investigate how OHC<br \/>\nexposure may affect biochemical pathways we collected blood plasma from Norwegian northern<br \/>\ngoshawk (n\u00bc56), golden eagle (n\u00bc12) and white-tailed eagle (n\u00bc36) nestlings during three<br \/>\nconsecutive breeding seasons. We found that blood plasma concentrations of calcium, sodium,<br \/>\ncreatinine, cholesterol, albumin, total protein, urea, inorganic phosphate, protein:creatinine, urea:-<br \/>\ncreatinine and uric acid:creatinine ratios and liver enzymes ALKP and ALAT were positively correlated<br \/>\nto PCBs, chlordanes, p,p0-DDE, HCB, PFCs and\/or PBDEs. Total bilirubin and glucose were negatively<br \/>\ncorrelated to PCBs while magnesium and potassium were negatively correlated to HCB and p,p0-DDE.<br \/>\nIn addition, protein:creatinine and ALAT were also negatively correlated to PCBs and PFCs, respectively.<br \/>\nThe most significant relationships were found for the highly contaminated northern goshawks<br \/>\nand white-tailed eagles. The statistical relationships between OHCs and BCCPs indicate that<br \/>\nbiochemical pathways could be influenced while it is uncertain if such changes have any health<br \/>\neffects. The OHC concentrations were below concentrations causing reproductive toxicity in adults of<br \/>\nother raptor species but similar to those of concern for endocrine disruption of thyroid hormones in<br \/>\ne.g., bald eagles.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 14:36:49","footnotes":""},"nva_tax_category":[1099],"class_list":["post-118754","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-scientific-journal-publication"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/118754","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication"}],"about":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/types\/nva_publication"}],"version-history":[{"count":0,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/118754\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=118754"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=118754"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
