원자흡광법에 의한 서울 지역 고수부지 토양과 잡초중의 중금속함량에 관한 연구 = Atomic Absorption Speetrophotometric Analysis of Heavy Metals Accumulated in River bed Soils and Plants in Seoul Area

다국어 초록 (Multilingual Abstract)

Heavy metals, because of their tendency to accumulate in biological system, can pose a health hazard to human. To investigate such a heavy metal, author executed this study of the quantitative analysis of zinc, copper and lead in river bed soil along with soil depthes and plants collected from the study sites.
Results obtained are summarized as follows:
1. As the pH of the river bed soi1 increased, calcium content in its soil increased.
2. The content of available phosphorus of river bed soils at the Anyang River tended to decrease from the upper stream to the lower but that of the Chungrang River was irregular trend.
3. Zinc and copper seemed to accumulate in the soil surface within the range of 0 to 2 centimeters, but lead in the soil depth within the range of 0 to 10 centimeters.
4. Heavy metal contents of river bed soils at the Anyang River were higher than those of the Chungrang River.
5. The principle purposes of the present study were to examine Zn, Cu and Pb acc-cumulations in Rumex coreanus N. and Persicaria hydropiper L. were higher than those in Humex coreanus N.
Zn content in Rumex coreanus showed the largest amount in leaf but that in Persicaria hydropiper the largest amount in stem.
Cu and Pb contents of both in Rumex coreanus and Persicaria hydropiper showed equally the largest amounts in root but smallest amounts in stem.
