Transportation and transformation of 14C-phenanthrene in closed chamber (nutrient solution-lava-plant-air) system

Abstract

Abstract: The transportation and transformation of ¹⁴C phenanthrene in a closed ‘plant lava nutrient solution air' chamber system was studied by using radioactivity technology. The results showed that in this closed chamber system,phenanthrene was degraded fast.The radioactivity of ¹⁴C left at 23d in the nutrient solution was only 25% of applied.At the end of experiment (46d),the distribution sequence of ¹⁴C activity in the components of closed chamber system was root (38.55%)>volatile organic compounds (VOCs, 17.68%)>lava (14.35%)>CO₂(11.42%)> stem (2%). ¹⁴C activities in plant tissue were combined with the tissue,and existed in the forms of lava bound(root 4.68%; stem and leaves 0.68%) and polar metabolites (root 23.14%; stem 0.78%).
