摘　　要：目的通过研究杭州市7个景区泉水的感官指标、溶解性总固体、酸碱度以及微量元素含量,了解目前杭州市区泉水水质的现状。方法以杭州市区居民日常取水人次较多的景区泉水点为分析对象,共7处采集点,测定各泉水TDS值及pH值,采用电感耦合等离子体发射光谱法(ICP-OES)进行16种元素含量的分析,根据GB 5749—2006《生活饮用水卫生标准》对泉水水质安全进行评估。结果杭州市7个不同景区居民日常饮用泉水的TDS值符合限值标准,pH值低于规定限值,部分水样Mn、Bi、Al、Hg元素超出限值。结论杭州市7个景区泉水均含有丰富的矿物元素,2处泉水点符合生活饮用水限量标准,5处泉水点有毒元素超出标准限量规定,不建议直接饮用超标地区的泉水。Objective To understand the current situation of the water quality in the urban area of Hangzhou through the study of sensory index, dissolved total solid, pH and trace element content in spring water from seven scenic spots. Methods The spring water points in scenic spots where Hangzhou urban residents intake the daily water more were used as the object for analysis. The TDS and pH value of each spring were determined and the 16 kinds of elements eontent were analyzed by inductively coupled plasma atomic emission spectrometry（ ICP- OES）. The spring water quality and safety were assessed according to GB 5749-2006 Drinking Water Health Standards. Results The TDS value of Hangzhou residents＇ daily drinking spring water is conformed to the limits standard in seven different scenic spots, the pH value is below the limit value, but Mn, Bi, Al and Hg elements are beyond the limit in some water samples. Conclusion The spring water in seven scenic spots are rich in mineral elements, 2 of which meet the drinking water standards limit, the other 5 are beyond the standard limit, so we do not recommend drinking spring water directly in exceeded region.
