Properties of Chinese Mineral Water

Abstract

In order to clarify the properties of Chinese Mineral Water, the various mineral contents, were determined and consumption of potassium permanganate, inorganic anions, volatile halogenated hydrocarbons, the number of viable aerobes and their genus level were determined for the sanitary properties.
(1) Chinese Mineral Water had more minerals contents than Japanese or Korean Mineral Water but lower than European Mineral Water. The distribution of hardness of the Chinese Mineral Water is similar to that of European Mineral Water of which the hardness is high.
(2) The average consumption of potassium permanganate was 1.33mg/l.
(3) Based on the K-index and 0-index, which means the taste of water, 38. 5% of the Chinese Mineral Water was judged to have a good taste.
(4) The contents of the inorganic anions and volatile halogenated hydrocarbons in 35 samples did not exceed the Japanese regulation limit, except fluorine ion of one sample.
(5) On the number of viable aerobes, half of the samples had under one hundred viable aerobes per lml and by the identification at the genus level, the genus Vibrio, Bacillus, Flavobacterium, Xanthomonas, Micrococcus, Stapylococcus, Leuconostocwere observed.
