We investigated the validity of the analytical procedures used for the determination of sulfide and trace metals. We found low relative standard deviations on replicate measurements, linear trace-metal calibration curves between the LA-ICP-MS signal and the true trace-metal concentration in the resin gel, and a good agreement of the sulfide results obtained with the AgI resin gel and with other analytical methods. The method was applied on anoxic sediment pore waters in an estuarine and marine system. Simultaneous remobilization of sulfide and trace metals was observed in the marine sediment.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Two-dimensional images of dissolved sulfide and metals in anoxic sediments by a novel diffusive gradients in thin film probe and optical scanning techniques","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:32:04.100485","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"DGT; Diffusive gradients in thin film; Dissolved sulfide;Inductively-coupled plasma; Laser ablation; LA-ICP-MS; Massspectrometry; Remobilization; Trace metal; 2D image","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2020-06-25","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000352248200014","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.trac.2014.11.012"},"refs":null,"anarec":{"AnaID":257069,"PubliDate":2015,"Pagination":"63-71","XtraPublOfAnaID":null,"ISBN":null,"Volume":"66","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45433,"SerRR":"Trends in Analytical Chemistry.
