摘　　要：运用ICP-AES法准确测定了西藏地区大骨节病区和非病区中沟水、河水、泉水和溪水等四种饮用水中Cu，Zn，Fe，Ca，Mg，Mn，A1，K，Ba，P，Sr，Cd，V，Cr，Ni，PB和Co等多种微量元素的含量。该方法的相对标准偏差在0．80G～2．83％之间，标准物质的测定结果满意，方法简单可靠。文章通过对测定结果的分析，得出西藏不同地区、不同饮用水类型中微量元素的含量差异，为改善西藏大骨节病区居民的生活饮用水提供了科学理论依据。Trace elements （Cu, Zn, Fe, Ca, Mg, Mn, Al, K, Ba, P, Sr, Cd, V, Cr, Ni, Pb and Co） concentrations in the drinking water of KBD-affected and non-affected areas were measured using ICP-AES. The RSD of this method was between 0. 80% and 2. 83%, and the analytical results of the reference samples were consistent with the certified values. The method was simple and accurate. The results indicated that there is an obvious difference in trace elements concentrations between KBD-affected areas and non-afffected areas. The results provided a scientific theoretical basis to improve the conditions of drinking water in KBD-affected areas in Tibet.
