Abstract

Heavy metals in the rice and rice paddy soil of Kyung Nam district were surveyed by use of MIBK extraction and atomic absorption spectrophotomter. Mercury was analyzed by nom-flame mercury vapor method. Rice paddy soil showed that cupper amounted to the level of $13.8{\sim}8.4ppm$, average value of 11.5ppm. Lead: $2.6{\sim}0.6ppm$, average 0.02ppm. The conentration of heavy metal $0.04{\sim}0.01ppm$, average 1.5 ppm, Zinc ; $16.1{\sim}7.2ppm$, average 11.3 ppm. Cadmium in rice were containted $2.59{\sim}0.16ppm$ of cupper, average value of 1.80 ppm. Lead: $0.2{\sim}N.D$, Zinc ; $0.11{\sim}0.60ppm$. Cadmium was shown trace at 4 places and mercury was shown trace at 6 places. Cupper showed the highest ratio of heavy metal. Levels in rice and soil whereas zinc showed the highest transmission from soil to rice.

1. 쌀 중의 구리 함량은 $0.62{\sim}2.59ppm$으로써 울주산에서 최고 함량이 검출되었다. 2. 납은 $0.06{\sim}0.2ppm$의 범위이며, 최고치는 진양산이었다. 3. 아연은 $0.11{\sim}0.61ppm$으로 진양산이 가장 높은 함량을 나타내었다. 4. 카드뮴은 시료 중 4개소만 검출되었고 0.004 ppm이하로 나타났었다. 5. 수은은 시료 중 6개가 검출되었으며 0.008ppm이하이었다. 6. 논흙과 쌀의 중금속 함량비는 구리에서 6:1, 납 14:1, 아연 56:1이고 카드뮴과 수은은 미량으로 나타났었다.
