사과 과수원토양과 그 잎중의 중금속 함량간의 상관관계에 관한 연구 = Originals : Studies on the Correlation between Heavy Metal Contents of Apple Orchard Lands and its' Leaves

다국어 초록 (Multilingual Abstract)

This study was performed to reveal the heavy metal contents in apple leaves, and to estimate the correlation between contents of heavy metals of orchard lands and those of apple leaves. For this experiment, the apple leaves were collected from 58 apple orchards in Korea. The results were as follows ; 1. The average heavy metal contents in apple leaves were 26.44(6,23-182,85) ppm in Cu, 0.34 (0.07-0,61) ppm in Cd and 9.47 (0.00-225.50) ppm in Pb. 2. On the simple correlation coefficients between contents of heavy metals of orchard lands and those of apple leaves, all three copper cadmium and lead were positive but cadmium was insignificanfly, correlated. There was no difference among varieties (Ralls, Jonathan, etc) in these results. 3. The 0.1N HCl extraetion proved, was more suitable than the lN-NH₄OAC extraction for describing the relation-Ship between heavy metal contents of apple leaves and those of orchard lands.
