经科学测定,人体血液中各种化学元素,微量元素平均值与地壳中元素的丰度值密切相关。矿泉水溶解了地壳中相关地层的矿物质,所以矿泉水中所含人体必需的微量元素和矿物质也最接近人体的自然状态。从营养学上讲,矿物质、微量元素在人体中所起的作用不亚于维生素,它的作用要比我们认识到的大得多。而且维生素可在人体内合成,矿物质则不行,只能外补。 相似文献

盘山花岗岩裂隙水研究 总被引：2，自引：0，他引：2
盘山花岗岩裂隙水起源于大气降水，赋存于各种成因的裂隙中，裂隙水年龄从小于４ａ到接近４０ａ，差异较大。裂隙水中常量元素和微量元素主要来源于长石类矿物的水解，特别是钙长石的水解，其中ＳｉＯ２和Ｓｒ在裂隙水中含量较高，已达到饮用矿泉水标准。裂隙水可开采资源量多年平均为１２９１．５６万ｍ＾３／ａ，富水规律明显。 相似文献

Uraniferous waters of the Arkansas River valley,Colorado, U.S.A.: a function of geology and land use
《Applied Geochemistry》1995,10(2):133-144
The effect of local geology and land-use practices on dissolved U was investigated by analysis of surface water and some springs in the Arkansas River valley of southeastern Colorado. Water samples were collected during a 2 week period in April, 1991. The rate of increase of U concentration with distance downriver increased markedly as the river flowed from predominantly undeveloped lands underlain by igneous and metamorphic rocks to agriculturally developed lands underlain by marine shale and limestone. An additional abrupt increase in dissolved U was observed along the section of river where discharge is often greatly reduced because of extensive diversions for irrigation and where remaining flow is largely composed of irrigation return water. Dissolved U in this last section of river and in most of its tributaries exceeded the proposed U.S. drinking water standard of 20 μ/L In water samples collected from agricultural areas dissolved U showed strong positive correlation with major dissolved constituents Na, Ca, Mg, and SO4 that increase as a result of sulfate mineral dissolution and clay mineral ion-exchange reactions in weathered shale bedrock and shaley soils. Highly soluble minor and trace elements Cl, Li, B, Sr, and Se that are not subject to strong sorptive uptake or precipitation in this setting also correlated positively with U. These combined observations indicate that natural leaching of U-bearing shale bedrock and derivative soils, additional leaching of rock and soil by irrigation water, and evaporative concentration in a semi-arid climate can produce concentrations of dissolved U in surface water and shallow ground water that may threaten nearby drinking water supplies. Other agriculturally developed areas of the semi-arid Western U.S. with similar geology are likely to contain high concentrations of U in irrigation drain water. 相似文献

The market for mineral water has been growing steadily over the last few years. Germany is the country with the highest number of bottled mineral water brands (908 bottled water samples from 502 wells/brands were analyzed). The per capita consumption of mineral water in Germany in 2003 was 129 L. A wide range of values of one to seven orders of magnitude was determined for 71 elements in the bottled water samples analyzed by ICP-QMS, ICP-AES, IC, titration, photometric, conductometric and potentiometric methods. A comparison of the element concentrations and the legal limits for both bottled and tap water (EU, Germany, US EPA, WHO) shows that only 70% of the 908 mineral water samples fulfill the German and EU drinking water (i.e., tap water) regulations for all parameters (not including pH) for which action levels are defined. Nearly 5% of the bottled water samples not fulfill the German and EU regulations for mineral and table water. Comparison of our results with the current German and European action levels for mineral and table water shows that only 42 of the bottled water samples exceed the limits for one or more of the following elements: arsenic, nitrate, nitrite, manganese, nickel and barium concentrations. Ten of the bottled water samples contain uranium concentrations above the 10 μg/L recommended limit. 相似文献

Twenty-two bottled mineral and spring waters from Norway, Sweden, Finland and Iceland have been analysed for 71 inorganic chemical parameters with low detection limits as a subset of a large European survey of bottled groundwater chemistry (N = 884). The Nordic bottled groundwaters comprise mainly Ca–Na–HCO3–Cl water types, but more distinct Ca–HCO3, Na HCO3 and Na–Cl water types are also offered. The distributions for most elements fall between groundwater from Fennoscandian Quaternary unconsolidated aquifers and groundwater from Norwegian crystalline bedrock boreholes. Treated tap waters have slightly lower median values for many parameters, but elements associated with plumbing have significantly higher concentrations in tap waters than in bottled waters. The small dataset is able to show that excessive fluoride and uranium contents are potential drinking water problems in Fennoscandia. Nitrate and arsenic displayed low to moderate concentrations, but the number of samples from Finland and Northern Sweden was too low to detect that elevated concentrations of arsenic occur in bedrock boreholes in some regions. The data shows clearly that water sold in plastic bottles is contaminated with antimony. Antimony is toxic and suspected to be carcinogenic, but the levels are well below the EU drinking water limit. The study does not provide any health-based arguments for buying bottled mineral and spring waters for those who are served with drinking water from public waterworks. Drinking water from crystalline bedrock aquifers should be analysed. In case of elevated concentrations of fluoride, uranium or arsenic, most bottled waters, but not all, will be better alternatives when treatment of the well water is not practicable. 相似文献
