Perylene, a five-ring nuclear polycyclic aromatic hydrocarbon (PAH), has a different distribution pattern from anthropogenic PAHs. Its source, however, remains obscure, limiting its application as an environmental indicator. Here we examine perylene in the upper 85m sediments of the ODP Hole 1202B from the southern Okinawa Trough. Over the past 20,000years, the mass accumulation rate of perylene is substantially higher in the last deglaciation than the Holocene and last glacial maximum. Perylene presents a strong correlation with C31n-alkane (r=0.55; p |

Over the past 20,000years, the mass accumulation rate of perylene is substantially higher in the last deglaciation than the Holocene and last glacial maximum. Perylene presents a strong correlation with C31n-alkane (r=0.55; p<0.001), a biomarker for terrigenous organic matter, and a weak correlation with C37:2 alkenone (r=−0.04; p=0.23), a biomarker for marine organic matter. The mean δ13C value of perylene (−22.8‰±0.6‰) is substantially higher than that of long chain n-alkanes (−30.7±0.4‰), but close to that of fluvial organic matter in adjacent areas (−24.0‰ to −25.0‰). Our results strongly suggest that the perylene is of a terrigenous origin likely from soil fungi, and may be a useful tracer for soil organic carbon in marine environments.</description><identifier>ISSN: 0146-6380</identifier><identifier>EISSN: 1873-5290</identifier><identifier>DOI: 10.1016/j.orggeochem.2014.09.008</identifier><language>eng</language><publisher>Oxford: Elsevier Ltd</publisher><subject>Biomarker ; Compound specific isotope analysis ; Earth sciences ; Earth, ocean, space ; Exact sciences and technology ; Hydrocarbons ; Marine and continental quaternary ; Marine geology ; Okinawa Trough ; Perylene ; Polycyclic aromatic hydrocarbons ; Sedimentary rocks ; Surficial geology</subject><ispartof>Organic geochemistry, 2014-11, Vol.76, p.288-294</ispartof><rights>2014 Elsevier Ltd</rights><rights>2015 INIST-CNRS</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-a404t-ee67128185242a6f38743a19a503f8f66aa6d52be056ffd2889b2df72fc8692f3</citedby><cites>FETCH-LOGICAL-a404t-ee67128185242a6f38743a19a503f8f66aa6d52be056ffd2889b2df72fc8692f3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://dx.doi.org/10.1016/j.orggeochem.2014.09.008$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,780,784,3550,27924,27925,45995</link.rule.ids><backlink>$$Uhttp://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&idt=28851100$$DView record in Pascal Francis$$Hfree_for_read</backlink></links><search><creatorcontrib>Zhang, Xinyu</creatorcontrib><creatorcontrib>Xu, Yunping</creatorcontrib><creatorcontrib>Ruan, Jiaping</creatorcontrib><creatorcontrib>Ding, Su</creatorcontrib><creatorcontrib>Huang, Xianyu</creatorcontrib><title>Origin, distribution and environmental significance of perylene in Okinawa Trough since last glaciation maximum</title><title>Organic geochemistry</title><description>•Relatively high abundance of perylene detected in Okinawa Trough over the past 20kyr.•Correlation of perylene was much stronger with long chain n-alkanes than alkenones.•Substantially different δ13C between perylene and long chain n-alkanes.•Perylene in Okinawa Trough is of a terrigenous origin likely from soil fungi.
