Abstract
3가지 농도의 납을 첨가한 토양에서 생장한 애기장대(Arabidopsis thaliana)에서 식물체에 축적된 납의 농도를 조사하였다. 환경부 고시 오염물질 배출기준 농도(1 mg/l)와 10배 높은 농도(10 mg/l) 및 50배 높은 농도(50 mg/l)의 납이 첨가된 토양에서 생장한 식물의 줄기에 축적된 납의 농도는 3가지 농도에서 증가율이 유사하게 나타났으며, 정상식물 줄기에 비하여 평균 약 24% 증가하였다. 3가지 농도의 납이 첨가된 토양에서 생장한 식물의 잎에 축적된 납의 농도는 정상식물 잎에 비하여 평균 약 57% 증가하였으며, 줄기와 마찬가지로 토양에 첨가된 납의 농도 증가에 따라 잎에 축적된 납의 농도는 유의한 차이는 나타나지 않았으며 증가율도 유사하였다. 반면 오염물질 배출기준 농도와 10배 높은 농도의 납이 첨가된 토양에서 생장한 식물의 뿌리에 축적된 납의 농도는 정상식물 뿌리에 비하여 평균 약 114% 증가하였으나, 50배 높은 농도에서는 약 861% 증가하여 줄기나 잎과는 대조적인 결과를 나타내었다. 토양 속에 첨가된 납의 농도가 증가하면 애기장대 식물체 내에 축적된 납의 농도도 증가하였는데, 특히 오염물질 배출기준농도보다 50배 높은 납이 첨가된 토양에서 생장한 식물체내에 축적된 납 농도는 정상식물보다 약 2.6배 증가하였다. 이러한 결과는 토양 속에 오염된 납은 식물의 줄기나 잎보다는 뿌리에 더 많이 축적되며, 줄기와 잎에 축적되는 납 농도는 토양 속에 오염된 납 농도에 비례하여 증가하지 않으나 뿌리에서는 농도에 비례하여 매우 증가하였음을 나타내고 있다. This study was to examine the accumulated concentration of lead in the organ of Arabidopsis thaliana grown in the soil added three different concentrations of lead. The accumulated concentrations of lead in the stem of plant grown in the soil added official standard concentration of lead of pollutant exhaust notified by the Ministry of Environment (1 mg/l), concentration ten times higher than the official standard concentration (10 mg/l) and concentration fifty times higher (50 mg/l) were similar to the rate of increase between three different concentrations, and increased average 24% compared with normal plant stem. The accumulated concentrations of lead in the leaf of plant grown in the soil added three different concentrations of lead were increased average 57% compared with normal plant leaf. And accumulated concentrations of lead in the leaf was no significant difference according to increase of lead concentration added in the soil as stem, the rate of increase was similar to between three different concentrations. The accumulated concentrations of lead in the root of plant grown in the soil added official standard concentration of lead of pollutant exhaust and concentration ten times higher were increased average 114% compared with normal plant root, but increased about 861% in the concentration fifty times higher than the official standard concentration. This result contrast with the data of stem and leaf. The accumulated concentration of lead in the plant body of Arabidopsis thaliana was increased according to increase of lead concentration added in the soil. Especially, the accumulated concentration of lead in the plant body grown in the concentration fifty times higher than the official standard concentration was increased about 2.6 times than normal plant. These results show that lead contaminated within the soil was more accumulated in the root than the stem or leaf, and accumulated concentrations of lead in the stem and leaf were not increased in proportion to the concentration of lead in the soil, but very increased in proportion to the concentration in the root.
