Abstract
This study was performed to survey the school supplies such as pencil, eraser, notebook and color paper. Twenty-two kinds of samples were collected near the school zone, and eight kinds of phthalate which is one of the environmental hazard factors analyzed to estimate the contents characteristics of products. As the results of these research, three kinds of phthalates (BBP, DNOP and DIDP) were not detected in the selected samples. In the A group, DEHP and DINP were detected in the rage of 22%~28%, and DINP was selected 28%, 24% and 28% in the A-1, A-3 and A-4 samples, respectively. But the selected samples in the B group were detected less than 1,000 ppm as regulated level. Also, The DBP was detected 1% in the C-2 sample, and DEHP was detected 0.3% in the C-1 and C-6 samples. The DEHA was detected 0.3% in the D-3 sample. In this study, the DINP was mainly detected the eraser, therefore this kind of phthalate can be exposed through dermal exposure.
