Abstract
Soils and rice plants in wastewater irrigated area of the Mangyeong River receiving waster from the Jeonju Industrial Complex and municipal sewage were sampled at two depths to assess the nature and content of Cd, Cu, Pb and Zn, particularly with respect to distance from wastewater source. For metal levels of soils in these area, no difference in the heavy metal contents between the surface and the subsurface soils was found. Total contents of Cu, Pb and Zn in soils were negatively correlated with distance from the source. A positive correlation was found between contents of total and 0.1N-HCl extractable or
전주시(全州市) 공단폐수(工團廢水) 및 도시하수(都市下水)의 영향(影響)을 받는 지역(地域)의 토양(土壤)과 수도(水稻)를 대상(對象)으로 Cd, Cu, Pb, 및 Zn등 중김속함량(重金屬含量)을 조사분석(調査分析)한 결과(結果)를 요약(要約)하면 다음과 같다. 1) 토양중(土壤中)의 중김속함량(重金屬含量)은 표토(表土)와 심토(心土)의 차(差)가 거의 없었다. 2) 토양중(土壤中)의 Cd, Cu, Pb, 및 Zn의 전함량(全含量)은 오염원(汚染源)으로부터 거리(距離)가 멀어질수록 부(負)의 상관(相關)을 나타냈다. 3) 표토중(表土中) Cd, Pb, Zn 함량(含量)과 0.1N-HCL 및
