The developed approach may permit a low-cost monitoring of these compounds in concentrations near the odor threshold concentrations (OTCs) of 20 ng\/L. The experiments demonstrate the success of the E-tongue in combination with partial least squares (PLS) regression technique for the GE\/MIB concentration prediction, showing also the possibility to discriminate tap water samples containing these compounds at two concentration levels: the same OTC order from 20 to 100 ng\/L and at higher concentrations from 0.25 to 10 mg\/L by means of PLS-discriminant analysis (DA) method. Based on the results, developed multisensory system can be considered a promising easy-to-handle tool for express evaluation of GE\/MIB species and to provide a timely detection of alarm situations in case of extreme pollution before the drinkable water is delivered to end users.<\/jats:p>","DOI":"10.3390\/s20030821","type":"journal-article","created":{"date-parts":[[2020,2,5]],"date-time":"2020-02-05T03:18:48Z","timestamp":1580872728000},"page":"821","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Potentiometric E-Tongue System for Geosmin\/Isoborneol Presence Monitoring in Drinkable Water"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1137-6973","authenticated-orcid":false,"given":"Larisa","family":"Lvova","sequence":"first","affiliation":[{"name":"Department of Chemical Sciences and Technologies, University \u201cTor Vergata\u201d, 00133 Rome, Italy"},{"name":"Laboratory of Artificial Sensory Systems, ITMO University, 197101 St. Petersburg, Russia"}]},{"given":"Igor","family":"Jahatspanian","sequence":"additional","affiliation":[{"name":"Laboratory of Artificial Sensory Systems, ITMO University, 197101 St. Petersburg, Russia"}]},{"given":"Luiz H.C.","family":"Mattoso","sequence":"additional","affiliation":[{"name":"Nanotechnology National Laboratory for Agriculture (LNNA), Embrapa Instrumentation, Sao Carlos 13560-970, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5592-0627","authenticated-orcid":false,"given":"Daniel S.","family":"Correa","sequence":"additional","affiliation":[{"name":"Nanotechnology National Laboratory for Agriculture (LNNA), Embrapa Instrumentation, Sao Carlos 13560-970, Brazil"}]},{"given":"Ekaterina","family":"Oleneva","sequence":"additional","affiliation":[{"name":"Laboratory of Artificial Sensory Systems, ITMO University, 197101 St. Petersburg, Russia"}]},{"given":"Andrey","family":"Legin","sequence":"additional","affiliation":[{"name":"Laboratory of Artificial Sensory Systems, ITMO University, 197101 St. Petersburg, Russia"},{"name":"Institute of Chemistry, St. Petersburg State University, 199034 St. Petersburg, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0543-4348","authenticated-orcid":false,"given":"Corrado","family":"Di Natale","sequence":"additional","affiliation":[{"name":"Laboratory of Artificial Sensory Systems, ITMO University, 197101 St. Petersburg, Russia"},{"name":"Department of Electronic Engineering, University \u201cTor Vergata\u201d, 00133 Rome, Italy"}]},{"given":"Roberto","family":"Paolesse","sequence":"additional","affiliation":[{"name":"Department of Chemical Sciences and Technologies, University \u201cTor Vergata\u201d, 00133 Rome, Italy"},{"name":"Laboratory of Artificial Sensory Systems, ITMO University, 197101 St. Petersburg, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,4]]},"reference":[{"key":"ref_1","unstructured":"UNESCO (2012).
