摘要

本研究以市面上常見的29種礦泉水、海洋深層水、冰河水等作為實驗材料，利用感應耦合電漿發射光譜儀（ICP－OES）進行金屬微量元素的檢測。
研究結果顯示，礦泉水、海洋深層水、冰河水等包裝水中之巨量礦物質元素Ca、Mg、Na、K大部份值介於2~20 ppm、1~25 ppm、1.5~12 ppm、0.1~1.4 ppm之間；微量礦物質Cu、Zn、Fe、Zn、Cr、Mn 、Sr大部份介於0.002~0.05 ppm、0.0035~0.035 ppm、0.05~0.1 ppm、0~0.003 ppm、0.0008~0.005 ppm、0.01~0.035 ppm，有害元素Pb、Cd、As、Hg、Ba大部份含量範圍為0~0.0006 ppm、0.0001~0.001 ppm、0.0001~0.0045 ppm、0.0001~0.0007 ppm、0.002~0.015 ppm之間。其檢測結果均低於包裝飲用水及盛裝飲用水衛生標準規定之最大容許量。
唯有部份包裝水中之巨量礦物質元素含量偏高，如「凌波怡-海神深層海水」為高鈉產品(200 ppm)，長期飲用可能會造成身體機能的負擔，患有腎臟病或心臟病的人需控制鈉的攝取，過量的鈉會引起水腫、高血壓，嚴重可能危及生命。「迪洛斯汀泉水汽泡礦泉水」、「可兒露露天然美身礦泉水」「Contrex純天然礦泉水」檢測結果含有豐富的鈣(362~532 ppm)與鎂(62.2~120 ppm)。飲用時勿過量，而腎結石患者應避免飲用高鈣之包裝水。礦物質並非多多益善，過量會增加身體負擔，危害健康，甚至造成重金屬中毒。

In present study 29 different bottled waters from the local market were analyzed. The bottled waters included mineral waters, deep ocean water, and glacial waters. The minerals in the waters were analyzed by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES).
The results indicated that concentration of Ca, Mg, Na and K wewe in the range of 2~20 ppm , 1~25 ppm , 1.5~12 ppm and 0.1~1.4 ppm , respectively for the bottled waters including the mineral waters, deep ocean waters, and glacial waters. The concentrations of Cu, Zn, Fe, Cr, Mn, and Sr were in the ranges of 0.002~0.05 ppm , 0.0035~0.035 ppm , 0.05~0.1 ppm , 0~0.003 ppm , 0.0008~0.005 ppm and 0.01~0.035 ppm , respectively. The concentrations of harmful heavy metals for Pb, Cd, As and Hg were in the ranges of 0~0.0006 ppm , 0.0001~0.001 ppm , 0.0001~0.0045 ppm and 0.0001~0.0007 ppm , respectively.
The results revealed that the mineral concentrations are lower than the national standard for the maximum tolerance of the Sanitary Standard for Bottled and Packaged Drinking Water.
It was found that the Rainboii-Hawaii Deep Ocean Water contained up to 200 ppm high concentration of sodium. High sodium foods or drinks should be avoided for the persons had kidney or heart diseases. The Gerolsteiner Sprudel natuarally Sparkling Mineral Water, the. Courmayeur Natural Diet Mineral Water and the Contrex Mineral Water contained high concentration of calcium ( eg 362~532 ppm ) and magnesium ( eg 62.2~120 ppm ). Persons who suffered from kidney stones should avoid high calcium and magnesium water. Proper amounts of minerals is beneficial for health. Over-consuming a kind of particular mineral might be harmful to health.
