Fecha de publicación: | 1-jun-2019 | Editor: | Springer Nature | Citación: | Environmental Science and Pollution Research 26(16): 16076-16084 (2019) | Resumen: | A study of organic compounds that caused a serious taste and odor episode of water supply in two residential areas in Catalonia (N.E. Spain) was carried out. Sweet and paint/solvent odor were the main descriptors used by consumers. Some cases of sickness and nausea were also associated with drinking water consumption by the consumers. Closed-loop stripping analysis (CLSA) combined with sensory gas chromatography and gas chromatography mass spectrometry detection were used to study the problem. As a result, 3-(trifluoromethyl)phenol (CAS number 98-17-9) was for the first time identified as a responsible of an odor incident in drinking water. Concentration levels of this compound were up to 17,000 ng/L in groundwater and up to 600 ng/L in distributed water. Odor threshold in water for 3-(trifluoromethyl)phenol was determined as 13 ng/L (45 °C). © 2019, Springer-Verlag GmbH Germany, part of Springer Nature. | Versión del editor: | https://doi.org/10.1007/s11356-019-04635-y | URI: | http://hdl.handle.net/10261/201463 | DOI: | 10.1007/s11356-019-04635-y |
