Traces can be found in coastal environments. Sorption and toxicity of C<sub>12</sub>-LAS congeners were studied in controlled conditions (2-3500 µg C<sub>12</sub>LAs/L) in five marine phytoplanktonic species, using standardized methods. IC<sub>50</sub> values ranged from 0.5 to 2 mg LAS/L. Sorption of <sup>14</sup>C<sub>12</sub>-6 LAS isomer was measured at environmentally relevant trace levels (4 µg/L) using liquid scintillation counting. Steady-state sorption on algae was reached within 5 h in the order dinoflagellate > diatoms > green algae. The sorption data, fitted a L-type Freundlich isotherm, indicating saturation. Desorption was rapid but a low LAS fraction was still sorbed after 24 h. Toxic cell concentration was 0.38 +/- 0.09 mg/g for the studied species. LAS toxicity results from sorption on biological membranes leading to non-specific disturbance of algal growth. Results indicate that LAS concentrations in coastal environments do not represent a risk for these organisms.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Sorption-desorption kinetics and toxic cell concentration in marine phytoplankton microalgae exposed to Linear Alkylbenzene Sulfonate","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Marine microalgae; Surfactant; Toxicokinetics; Sorption coefficient","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2015-11-05","DateCreate":"2011-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000291133500021","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.marpolbul.2011.02.051"},"refs":null,"anarec":{"AnaID":211363,"PubliDate":2011,"Pagination":"942-947","XtraPublOfAnaID":null,"ISBN":null,"Volume":"62","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43520,"SerRR":"Marine Pollution Bulletin.
