Department of Food Evaluation/ Division of Food Contaminants, Korea Food and Drug Administration, 5 Nokbun-dong, Eunpyung-gu Seoul 122-704, Korea, Seoul, 122-704, South Korea There has been a growing attention to the contamination of heavy metals such as lead and cadmium in agricultural products due to the industrial development. Therefore, this study was conducted to estimate the contents of lead and cadmium in cereals, pulses and potatoes available on Korean markets. The samples were digested with acids, then analyzed by an inductively coupled plasma spectrometer for the contents of lead and cadmium. The mean values of lead in cereals, pulses and potatoes were 0.13 mg/kg, 0.12 mg/kg and 0.08 mg/kg respectively. Also the mean values of cadmium in cereals, pulses and potatoes were 0.023 mg/kg, 0.03 mg/kg and 0.017 mg/kg respectively. We observed that lead and cadmium contents in cereals, pulses and potatoes on our markets were similar to those reported in other countries. Our average weekly intakes of lead and cadmium from cereals, pulses and potatoes takes about 0.6-19% of PTWI(Provisional Tolerable Weekly Intakes) that FAO/WHO Joint Food Additive and Contaminants Committee has set to evaluate their safeties.
