Abstract
The material of polycarbonate tableware (n=20) for school lunch contained 22〜111 ppm of Total bisphenol A (T-BPA: bisphenol A, phenol and p-tert-butylphenol), but these migration were all under 0.05 ppm of T-BPA. The concentration of T-BPA in the material of new polycarbonate tableware (n=9) were lower than those of the used products (n=9). This is probably due to the conversion of the material in the used products over 4 years.
