Abstract | The investigation was designed to determine the odor thresholds in water of organic pollutants that have been identified in industrial effluents. Seven to fourteen judges were used to determine the odor threshold values of 13 compounds at room temperature and 60C. Odor threshold values for the compounds in ppm at room temperature are acenaphthene, 0.08; 2-ethyl-1-hexanol, 1.28; butanol, 2.77; geosmin, 0.00013; 2-methyl naphthalene, 0.01; 1-methyl naphthalene, 0.02; diacetone alcohol, 44.1; dibenzofuran, 0.12; 2-benzothiazole, 0.08; 2-mercaptobenzothiazole, 1.76; 2-ethyl-4-methyl-1,3-dioxolane, 0.38; caprolactam, 59.7; d-camphor, 1.29. Extreme value calculations were made to predict a concentration below which a certain percentage of the population might still be able to detect the compound(s). |

Contents Notes | This investigation was designed to determine the odor thresholds in water of organic pollutants that have been identified in industrial effluents. Seven to fourteen judges were used to determine the odor threshold values of 13 compounds at room temperature and 60[degrees]C. Odor threshold values for the compounds in ppm at room temperature are: acenaphthene, 0.08; 2-ethyl-1-hexanol, 1.28; butanol, 2.77; geosmin, 0.13 x 10 -3; 2-methyl naphthalene, 0.01; 1-methyl naphthalene, 0.02; diacetone alcohol, 44.1; dibenzofuran, 0.12; 2-benzothiazole, 0.08; 2-mercaptobenzothiazole, 1.76; 2-ethyl-4-methly-1,3-dioxolane, 0.38; caprolactam, 59.7; d-camphor, 1.29. Extreme value calculations were made to predict a concentratioin below which a certain percentage of the population might still be able to detect the compound(s). The threshold values obtained at 60[degrees]C in most cases do not differ or are higher than those determined at room temperature. |
