埴土에서 石炭灰 施用이 土壤重金屬에 미치는 影響 = Influence of Fly Ash Application on Content of Heavy Metal in the Clay soils

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the influence of treatment of fly ash on heavy metal contents in the clay soils.
Chinese cabbage was cultivated on the five treatments types of clay soil with non-fertilizer, N.P.K, 4, 8, 12ton/ha of bituminous coal, respectively. on the growth time, the heavy metal contents in surface soils was investigated. The results were summarized as follows:
The average contents of Pb, Cd, As, Zn of fly ash application to soils which were lower level than vegetable cultivated, plastic film house, fruit tree, upland in soils of korea. in the case of Cu, Ni, Cr were high respectively, because of contents of natural heavy metal in soils were characteristic of high, but all of fly ash treatments in soils tend to lower than countermeasure the range of crops injure and contamination indicators described in Soil Environmental Conservation Act of Korea(1996. years.).
