Abstract
This study has been conducted to provide a management plan for recycled products (plastic wastes) by identifying hazardous substances present in it and conducting exposure assessment. The concentration of 7 heavy metals (Cd, Cr, Cu, Fe, Hg, Pb, Zn) was analyzed. Exposure scenario was assumed by the consumption of kimchi made in a recycled plastic bucket. According to the analysis, all of the analyzed samples were within the food code standard level except one sample (137.03 mg/kg, sum of Cd, $Cr^{6+}$, Pb and Hg). In leaching test, all of heavy metals were within the leaching standard (Standards specifications of utensil and container-Packing). In an oral exposure test, Fe, Pb and Zn were detected in cabbages and were below PMTDI (Provisional Maximum Tolerable Daily Intake). As one of the recycled plastic buckets exceeded the standard level, we conclude not to recommend the recycled plastic buckets for cooking purpose.
