Additionally, spatial differences between the populations in the Baltic Sea and Atlantic<br \/>\nOcean (i.e. Iceland and Norway) and the influence of the body mass, age and sex on the PFAS concentrations<br \/>\nwere examined. Perfluorooctane sulfonate (PFOS) was the predominant compound with a concentration<br \/>\nrange of 160\u20132425 ng\/g wet weight (ww), followed by perfluorooctane sulfonamide (PFOSA, 1\u2013237 ng\/g<br \/>\nww) and perfluoroundecanoate (PFUnA, 3\u2013124 ng\/g ww). In terms of temporal trends, perfluoroalkyl sulfonates<br \/>\n(PFSAs) and PFOSA concentrations decreased over time, while, conversely, the C9\u2013C13 perfluoroalkyl<br \/>\ncarboxylate (PFCA) concentrations increased. Spatial distribution of the contaminant concentrations showed<br \/>\nconsistently higher concentrations in the Baltic Sea and lowest concentrations in the Icelandic population of<br \/>\nthe Atlantic Ocean.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-06-29 14:41:53","footnotes":""},"nva_tax_category":[1059],"class_list":["post-93500","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\/93500","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":1,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/93500\/revisions"}],"predecessor-version":[{"id":93501,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/93500\/revisions\/93501"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=93500"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=93500"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
