Abstract: The effect of elution of trace elements with water, acetic acid and boil treatments from aluminum cookware was investigated. Water samples in an aluminum cookware were subjected to three treatments and the concentrations of fifteen trace elements（ B, Al, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Mo, Cd, Sb, Pb and U） were simultaneously analyzed by inductively coupled plasma-mass spectrometry（ ICP-MS）. The following results were observed: Fifteen elements were detected in most samples from each treatment. The concentrations of Al which was the main material of the aluminum cookware in each sample were remarkably high. Mn, Ni and Zn were materials contained in the aluminum base alloy. The concentrations of these minerals in each sample were high. Al, Mn, Ni and Zn in water samples of ２h-boiling with acetic acid treatment were highest, and the concentrations of four elements in the samples of 24h-settling with acetic acid at 20℃ treatment were higher than the case of 24h-settling with the water treatment, respectively. The safety level concentrations for enamel cookware are standardized at Pb（ 400μg/L） and Cd（ 70μ g/L）. In this study using aluminum cookware, Pb and Cd concentrations in all treatment samples were below the standard levels for enamel cookware.
