[Determination of trace elements in drinking water of Kashin-Beck disease (KBD) affected and non-affected areas in Tibet by ICP-AES].
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.
