While the partial pressure of CO<sub>2</sub> (<i>p</i>CO<sub>2</sub>) was measured at 15 sites using syringe equilibration, 3 cruises employing an equilibrator were done along a 30 km transect in the Seoul metropolitan area. The basin-scale survey revealed longitudinal increases in surface water <i>p</i>CO<sub>2</sub> and dissolved organic carbon (DOC) in the downstream reach. Downstream increases in <i>p</i>CO<sub>2</sub>, DOC, fluorescence index, and inorganic N and P reflected disproportionately large contributions from wastewater treatment plant (WWTP) effluents carried by major urban tributaries. Cruise transects exhibited strong localized peaks of <i>p</i>CO<sub>2</sub> up to 13 000 μatm and <sup>13</sup>CO<sub>2</sub> enrichment along the confluences of tributaries at an average flow, whereas CO<sub>2</sub> pulses were dampened by increased flow during the monsoon period. Fluctuations in <i>p</i>CO<sub>2</sub> along the eutrophic reach downstream of the confluences reflected environmental controls on the balance between photosynthesis, biodegradation, and outgassing. The results underscore WWTP effluents as an anthropogenic source of nutrients, DOC, and CO<sub>2</sub> and their influences on algal blooms and associated C dynamics in eutrophic urbanized river systems, warranting further research on urbanization-induced perturbations to riverine metabolic processes and carbon fluxes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"CO<sub>2</sub> outgassing from an urbanized river system fueled by wastewater treatment plant effluents","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:21.550324","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2020-10-09","DateCreate":"2020-10-08","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000411549800022","VABBcode":null,"OpenAcc":0,"DOI":"10.1021/acs.est.7b02344"},"refs":null,"anarec":{"AnaID":330009,"PubliDate":2017,"Pagination":"10459-10467","XtraPublOfAnaID":null,"ISBN":null,"Volume":"51","Issue":"18","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42837,"SerRR":"Environmental Science and Technology.
