摘　　要：目的了解包头市黄河水源地11种微量元素的含量。方法于2009—2011年平水期(1—3和10—12月)、枯水期(5—7月)、丰水期(4和8—9月)月初(1—5日),采集黄河包头段对照断面(上游的昭君坟)、控制断面(黄河中游的画匠营子)、出境断面(黄河下游的磴口)水样,测定水中砷、铬、镉、汞、铅、氟、铜、锌、铁、锰、硒11种微量元素的含量。结果11种元素含量均未超标。2009年枯水期氟、硒含量,2011枯水期锌、硒、镉含量均较高。2011年对照断面水样中铬含量低于控制断面、出境断面,差异均有统计学意义(P<0.05);3个断面其他元素含量间无显著变化。结论各年度包头市饮用水水源微量元素含量虽有波动,但仍处于安全水平。Objective To investigate the contents of 11 kinds of elements in Baotou reach of Yellow River. Methods At the beginning of each month（the 1st to 5th） in the normal season （January to March,and October to December） , dry season（May to July）,and wet season （April,August and September） between 2009 and 2011,water samples were collected in the contrast section （Zhaojun graves at the upper reaches） , control section （Huajiangyingzi in the middle reaches） , and exit section （Dengkou at the lower reaches）, respectively. The contents of arsenic, chromium, cadmium, mercury, lead, fluorine, copper, zinc, iron, manganese and selenium were determined. Results The contents of 11 elements did not exceed the national standards. In the dry season,the contents of fluorine and selenium in 2009,the mercury content in 2010,and the contents of zinc,selenium and cadmium in 2011 were relatively higher. In 2011 ,the content of chromium in contrast section was significantly lower than that in the control section and exit section, and for the other elements, no significant differences were observed among three sections. Conclusion According to the contents of elements,the water source is safe in Baotou.
