The programme started in 2013 and has since been altered\/advanced.<br \/>\nIn 2024 the programme covers sampling and analyses of water, water moss,<br \/>\ninvertebrates, and trout from Alna River, as well as stormwater from Eastern Oslo<br \/>\nCity. A sampling campaign was also conducted for source tracing of chlorhexidine,<br \/>\ndichloromethane and trichloromethane previously found in Alna River. A total of<br \/>\n\uf07e240 single compounds\/isomers were analyzed, and frequent detection was found<br \/>\nof specifc PFAS compounds in aqueous phases, other specifc PFAS compounds in<br \/>\ntrout liver, UV-compounds and certain QACs in the particulate fraction of<br \/>\nstormwater, certain benzothiazoles in stormwater (dissolved and\/or particulate<br \/>\nfraction) , chlorinated paraffns (MCCP and LCCP) in biota, certain siloxanes in<br \/>\nnearly all matrices, metals in all matrices, and PCBs in biota. Biomagnifcation was<br \/>\nonly observed for a couple of the PCB congeners. However, as expected,<br \/>\nbiomagnifcation was observed for mercury and PFOS. Biomagnifcation of silver<br \/>\nwas observed when trout was represented by liver samples, but not muscle samples.<br \/>\nThe source tracing showed the presence of the compounds at several stations<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-06-26 13:14:54","footnotes":""},"nva_tax_category":[1055],"class_list":["post-85398","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-report"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/85398","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\/85398\/revisions"}],"predecessor-version":[{"id":85399,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/85398\/revisions\/85399"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=85398"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=85398"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
