| 摘 要： | 利用放射性同位素示踪技术研究了１４Ｃ标记菲在有控系统中的迁移转化．结果表明，１４Ｃ菲在有控系统中降解较快，施入药品２４ｄ后仅有０．３２％的１４Ｃ－菲存留在植物、营养液和火山石中．植物吸收的１４Ｃ放射性大部分被结合到植物组织中，其它１４Ｃ主要以菲的极性代谢物形态存在．

| Abstract: | With isotopic techniques, the transportation and transformation of 14 C phenanthrene in a controlled nutrient solution(NS) lava wheat system was conducted. The results suggest that after applied for 24 days, 14 C phenanthrene in the controlled system degraded fast, and only 0.32 % of it remained in the plant, NS and lava. Most of 14 C activity absorbed by plant was incorporated in plant tissues, and the remains existed prominantly as polar metabolites of phenanthrene. |
