| Abstract: |
| The soil for test was sampled from arid oasis region and the characteristics of transfer and enrichment of Cd, Zn and Pb in soil-
celery system was investigated through pot experiments. The results show that with the increase of concentrations of heavy metals added into the soil, the concentrations of heavy metals in celery roots and leaves also increase; There are extremely significant linear relationship between the contents of the three heavy metals accumulated in celery roots and their contents in soil; The linear relationship between the contents of Cd and Zn accumulated in celery leaves and their contents in soil is also extremely significant. The regression analysis shows that the uptake of Cd, Pb and Zn by celery is not affected by co-existent elements; The enrichment factors of heavy metals from soil to root and leaf is in the order of Cd>Zn>Pb, and the transfer factors of heavy metals in celery is in the order of Zn>Cd>Pb. |
