This study was performed to survey and evaluate contents of Pb and Cd in colored plastic kitchenwares by Korea Food Sanitation Act. The tested samples were 160 products(32 PE, 65 PP, 10 PS, 18 ABS and 35 MF) in a local market. The Pb and Cd contents range in the samples were ND~357.l㎎/㎏ and ND~376.6㎎/㎏. Pb contents in 6 samples(1 PE, 1 PP, 2 PS and 2 MF) and Cd contents of 2 samples(1 PE and 1 ABS) were above the legal limits. Among the illegal smples, Pb contents were 140.8㎎/㎏, 283.4㎎/㎏, 134.0㎎/㎏, 329.2㎎/㎏, 357.l㎎/㎏ and 218.3㎎/㎏, respectively and Cd contents were 123.l㎎/㎏ and 376.6㎎/㎏. Pb and Cd in various food simulants were not detected in migration test for illegal samples. Simulants were tested at 25℃ and 60℃ for n-heptane and 4% acetic acid, and 60℃ and 95℃ for water.
