摘　　要：[目的 ]探讨微量元素在深层地下水中的含量。 [方法 ]采集生活饮用深井水样 2 59份 ,按GB5750 85《生活饮用水标准检验法》进行水质分析 ,石墨炉原子吸收光谱法测定金属元素。 [结果 ]第四系深层地下水中 ,微量元素铁、锰、铜、锌、砷、硒、汞、镉、铬、铅、银、铍、硼、钡、镍、锑、钛、铊、钒、钴和钼的含量 (μg/L)分别为 1 3 68、8 92、2 97、1 3 69、<1 0、<5、<0 2、2 2 3、7 47、2 72、0 36、1 1 1、<1 0 0、4 74、5 1 5、0 99、1 63、0 0 4 0、1 53、4 81和 7 94;且多数元素含量枯水期高于丰水期。部分元素在岩石层以下的奥陶系水与第四系水的含量有差异 (P <0 0 5)。 [结论 ]取得了第四系深层地下水中 2 1种微量元素的含量 ,该值受地质结构影响 。To explore the contents of 21 trace elements in deep well ground water. Analysis on the water samples ( n =259) collected from the deep well was carried out,according to GB5750 85 Standard Examination Methods for Drinking Water. Contents of metallic elements were determined by graphite furnance atomic absorption spectrophotometry. The contents (μg/L) of Fe,Mn,Cu,Zn,As,Se,Hg,Cd,Cr,Pb,Ag,Be,B,Ba,Ni,Sb,Ti,T1,V,Co and Mo were respectively 13 68,8 92,2 97,13 69,<10,<5,<0 2,2 23,7 47,2 72,0 36,1 11,<100,4 74,5 15,0 99,1 63,0 040,1 53,4 81 and 7 94 in deep well ground water (the quarternary system);the contents of most trace elements were higher in drought period than those in flood water period. Some elements in Ordovician system water were different from those in the quarternary system water( P <0 05). [Conclusion] The contents of trace elements in deep well ground water (the quarternary system)were detected and had been impacted by geological structure,and they could be varied with water period.
