An investigation on some metal contents in acasia plant and soil around the main road in Ulsan
Abstract
울산시 일원 및 고속도로변의 아카시아 잎과 줄기 그리고 토양 속에 포함된 금속성분 함량을 원자흡수분광기를 이용하여 분석하고, 토양 중의 성분함량과 식물에 포함된 양과의 관계를 비교 ?愾鄂臼눼?.

시료의 전 처리조작은 아카시아의 잎과 줄기에 대하여는 건식회화법(dry ashing method)으로 실시하였으며, 토양시료는 왕수-과염소산을 사용하는 습식익힘법(wet digestion method)으로 처리하였다.

분석결과 토양시료에서는 Cr: 5.4∼18ppm, Zn; 33∼204ppm, Ni: 14.9∼29.4ppm, Mn: 225~899ppm, Cu; 11.5∼28.4ppm, Pb: 16.6~73.9ppm, Cd: 0.47∼1.12ppm, Fe: 1.46%∼2.89%, Ca: 28.5~1,816ppm, Mg: 797∼6,105ppm사이의 값을 보여주었다.

아카시아의 잎과 줄기에서는 Cr: 0.15∼1.66ppm, Zn: 12∼360ppm, Ni: 3.3∼22.3ppm, Mn: 9.0~375ppm, Cu: 4.2∼19.2ppm, Pb; 1.33∼7.89ppm, Ca: 4,297∼14,663ppm, Mg; 528~4,002ppm, Fe; 25∼720ppm사이의 값이었으며, 모든 금속성분들은 대부분의 지역에서 잎보다 줄기에 많이 포함되어 있었다.

석유화학단지화 온산 비철금속단지에서 채취한 시료에는 모든 성분들이 타 지역보다 많이 포함괴어 있는 것으로 나타났으며, 납 성분은 일반적으로 교통량이 많은 지역의 토양시료에서 높은 값을 보였다.

토양의 pH는 전 지역이 pH 4.17∼6.64로서 산성화되었음을 보였다.
Some metal components contained in leaves and tanks of acasia plant and in soil in Ulssn and its outskirts were determined by atomic absorption spectrometer to study the relation between the components in soil and plant samples.

Acacia sample was prepared by the dry ashing method, on the other hand, the soil sample was prepared by the wet digestion method using aqua regia-perchloric acid system.

The analytical result was appeared as follows :

(1) soil sample-Cr: 5.4-18ppm, Zn: 33-204ppm, Ni: 14.9-29.4ppm, Mn: 235-899ppm, Cu: 11.5-28.4ppm, Pb: 16.6-73.9ppm, Cd: 0.47-1.12ppm, Fe : 1.46-2.89%, Ca: 28.5~1,816ppm, Mg : 797-6,105ppm.

(2) Acasia sample-Cr: 0.15-1.66ppm, Zn: 12-360ppm, Ni: 3.3-22.3ppm, Mn; 9.0-375ppm, Cu: 4.2-19.2ppm, Pb: 1.33-7.89ppm, Ca: 4,297-14,663ppm, Mg; 528-4,002ppm, Fe: 25-72Oppm.

Most metal components in acasia trunk were higher than the one in leaves.

The samples in petrochemical complex and Osan nonferrous metal complex had higher metal contents than the other one.

The soil samples around the road where there is much traffic showed higher lead content than the other ones.

In general, the pH of all soil samples were in the acidic range between 4.17 and 6.64.
