Popis:	A rapid determination method for emergency response to health crisis caused by metals in foods, was developed using microwave decomposition equipment and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The method was assessed for 18 elements (Al, As, B, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Sn, Tl and Zn) in 5 kinds of beverages and 7 kinds of foods. A single-laboratory method validation study was performed using food samples added with 20 mg/kg of each metal. Trueness was 88-108% and intralaboratory reproducibility was 0.2-11.3%. Time required for analysis was less than 3 hr. Thus, the presented method could be useful for rapid analysis of metals involved food poisoning cases.
