Abstract

Mercury and cadmium concentrations were analyzed for 112 brown rice samples collected from various production areas of Korea in 1976 and the results obtained were as follows: 1) Mercury concentrations were found in the range of non-detectable to 0.310 ppm, with an average of 0.053 ppm for the whole samples. Two samples from Kimpo area showed $5{\sim}6$ times higher concentrations than the average value. 2) Cadmium concentrations were found in range of trace to 0.029 ppm, with an average of 0.021 ppm for the whole samples. No specific site was found to be seriously contaminated by cadmium as far as the present survey was concerned.

전국에서 수집된 1976년산 현미(玄米)시료 112점중 수은과 카드뮴의 농도를 분석, 비교한 결과는 다음과 같다. 1) 현미중 수은 농도의 검출 범위는 불검출${\sim}0.310\;ppm$이었으며 전국평균치는 0.053 ppm이었다. 다만 김포(金浦)지역에서의 시료는 평균치의 $5{\sim}6$배에 이르고 있었다. 2) 현미중 카드뮴 농도의 검출 범위는 흔적${\sim}0.029\;ppm$이었으며 전국 평균치는 0.021 ppm으로서 카드뮴으로 오염되었다고 생각되는 특정 지역은 발견되지 아니하였다.
