Fate of pyrene in the rhizosphere
- Kansas State Univ., Manhattan, KS (United States)
The objective of this research is to investigate the impact of vegetation on the fate of toxic and recalcitrant pyrene in soil as well as the influence of different plant species (alfalfa (Meticago sativa) and fescue (Festuca arundinacea)). The effect of vegetation will be evaluated by determining the distribution of {sup 14}C among soil, plant tissue, leachate, and CO{sub 2} evolved in planted and unplanted soils using highly controlled plant growth chambers during a 6-month experiment. The influence of plant species on the fate of pyrene will be estimated by comparing the dissipation rate of the {sup 14}C-target compound between alfalfa and fescue. These data will be analyzed to ascertain if there are differences between vegetated and nonvegetated soils, also between plant species with regard to leaching, degradation, plant uptake, mineralization of the {sup 14}C-labelled pyrene. The beneficial effects of vegetation planted in soil contaminated by pyrene is anticipated.
