| Abstract/Contents: | "Although polycyclic aromatic hydrocarbons are common contaminants in soil and are potentially carcinogenic and mutagenic, little is known about their fate in the soil/root environment. The impact of tall fescue (Festuca arundinacea Schreber) on chemical and biological transformations of benzo[a]pyrene in soil was investigated in a greenhouse experiment in which ¹⁴C-benzo[a]pyrene in soil was added to soil and placed in sealed chambers with and without plants. The distribution of ¹⁴C in soil, plant tissue, and CO² was quantified. Dissipation due to mineralization and volatilization accounted for <2% of the total ¹⁴C added in both planted and unplanted chambers and was greater in the presence of plants. Plant uptake of ¹⁴C was <0.12%. Residual benzo[a]pyrene was lower in soil with plants (44%) than in the absence of plants (53%). The majority of the ¹⁴C label was associated with the soil matrix. The presence of plants enhance the degradation of highly adsorbed, recalcitrant benzo[a]pyrene in soil." |
