The analysis of hazardous heavy metals, such as Pb, Cd and As, was conducted from the porcelain dinnerwares. Total 374 samples of those products in the domestic market were purchased for the study. All the samples were extracted by 4% acetic acid solution, followed by the analysis with AAS(Atomic Absorption Spectroscopy). As a result, Pb and As were detected maximum 8.63$\mu\textrm{g}$/ml, 2.58 ng/ml, respectively. Cd was fecund in a sample as 0.10$\mu\textrm{g}$/ml.
