A relationship between odors and concentrations of harmful substances (benzene, toluene and xylene) in water samples containing mineral oils (gasoline, kerosene, light oil and heavy oil) was investigated. Initially, water samples containing various concentrations of mineral oils were prepared by addition of mineral oils into purified water. In the case of water samples that almost all of volunteers did not feel smells on an organoleptic odor test, concentrations of harmful substances were below the water quality standard level given by the Ministry of Health, Labour and Welfare of Japan and so on. In the case of water samples containing 1 or 10 mg/L of mineral oils, almost all of volunteers answered“feel smells”on the odor test. However, after boiling for 5 minutes, odors were lowered and concentrations of harmful substances were reduced to lower detection limit levels.
