Both polychaete species were capable of rapidly accumulating and eliminating pyrene. Steady state concentrations of pyrene were established in both polychaete species within 5 days of exposure to contaminated sediments, with <i>A. marina</i> having 5-10 times higher bioaccumulation factors than <i>N. diversicolor</i>. Both water-soluble and water-insoluble metabolites were detected in tissues of <i>N. diversicolor</i> and <i>A. marina</i>. After transferring worms to uncontaminated sediment, about 50% of the body burden of parent pyrene was excreted within 1.5 days, with elimination in <i>A. marina</i> being faster than in <i>N. diversicolor</i>. The only identified water-insoluble metabolite produced by <i>N. diversicolor</i> was 1-hydroxypyrene. Pyrene metabolites were present in <i>A. marina</i>, but could not be identified. Long- and short-term absorption experiments showed an increasing production of water-soluble metabolites over time in the lugworm, which strongly suggests the presence of a PAH metabolising system in <i>A. marina</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Metabolism of pyrene by the polychaetes <i>Nereis diversicolor</i> and <i>Arenicola marina</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:05.484062","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"Pyrene; Bioaccumulation factor","Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2003-03-18","DateCreate":"2003-03-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000175544700002","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0166-445X(01)00217-X"},"refs":null,"anarec":{"AnaID":33251,"PubliDate":2002,"Pagination":"15-25","XtraPublOfAnaID":null,"ISBN":null,"Volume":"58","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42203,"SerRR":"Aquatic Toxicology.
