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.
The migration and transformation of 14C-labeled phenanthrene in a controlled system was studied by radioisotope tracer technique. The results showed that 14C-Philippines degraded rapidly in the controlled system and only 0.32% of 14C-phenanthrene remained in the plant, nutrient solution and volcanic rock after 24 days. Most of the 14C radioactivity absorbed by plants is incorporated into plant tissues, while the other 14C is mainly present in the form of the polar metabolite of phenanthrene.
