Effects of Heavy Metal Contents in Soil on the Growth of and their Uptake by Red pepper

토양중 중금속함량이 고추의 생육 및 중금속 흡수에 미치는 영향

When red pepper was cultivated in the polluted soil with heavy metals, the content of these heavy metals affected. The contents of heavy metals at a site near Zinc mine dump in the Youngyang area were very high compared with those in a normal area and it was highest in 2.0km site. followed 2.5km > 3.0km apart from Zinc mine dump. The growth of red pepper was remarkably poor and the contents of heavy metals in polluted soil were higher than in unpolluted soil. The relationship between the content of Zn, Cu, Pb, Cd, As and the growth of red pepper was negatively correlated, respectively. A higher correlation seemed to exist among the content of Zn.Cu, Cd, As in soil, of Zn, Cd, and As in red pepper. The result indicated that heavy metals were absorbed and accumulated by plants grown in the polluted area.

1. 영향의 광산하류 오염지역의 토양중 중금속함량은 비오염지역인 칠곡에 비해 중금속함량이 현저히 높았고, 광산으로부터 거리별 토양중 중금속함량은 2.0 > 2.5 > 3.0km 순으로 함량이 낮았다. 2. 중금속 오염지역의 고추 생육은 정상지역보다 극히 불량하였고 토양 및 고추중 중금속함량도 월등히 많았다. 3. 고추생육과 토양중 Zn, Cu, Pb, Cd, As함량과는 유의한 부의 상관이 인정되었다. 4. 토양중 Zn, Cu,Cd,As함량과 고추의 Zn, Cd, As함량과는 고도의 유의성이 있는 것으로 보아 중금속 오염지에서는 식물체에 흡수 축적되는 것으로 생각되었다.
