 note = {In order to clarify the quality of drinking water from environmental health viewpoint, the mineral and salt contents of drinking water from non-calcareous water sources in Okinawa prefecture were determined. In this study, the following 5 sources of the minerals and salts in the drinking water were investigated: 1) rainwater, 2) marine salts carried by the wind, 3) rock and soil, 4) human activity and 5) treatment chemicals. Water samples from these sources were analysed. The main findings were as follows: A) Large quantities of minerals and salts from marine, rock and soil sources were found in Okinawan drinking water. B) Amounts of Ca^<2+>, Na^+, Cl^-, SO^<-->_<4> and HCO^<->_<3^-> in the drinking water collected from non-calcareous sources were increased by the water purification method. C) The Na^+ and Cl^- contents of the non-calcareous water sources were influenced by human activities. However, these influences were very small in comparison with calcareous water sources., 論文},
