Glazed ceramic containers containing hazardous substances （lead, cadmium, chromium and nickel, cobalt, zinc, antimony）were prepared and 4% acetic acid was selected as leaching liquid. Inductively coupled plasma atomic emission spectrometer was applied to measure leaching amount of hazardous substances in different immersion time. Correlation between immersion time and leaching of hazardous substances was analyzed. The results showed that, leaching quantity of hazardous substances in the ceramic packaging container increases gradually with leaching time; coexisting elements interference between each other; the elements to be detected is influenced greatly by the dissolution of coexistence elements.
