| Abstract | The ability of butterfly pea (Clitoria ternatea) and yam bean (Pachyrhizus erosus) to stimulate the removal ofanthracene and pyrene from contaminated soil was investigated. Of the two plants, only butterfly pea enhanced the removal ofanthracene and pyrene from soil on day 30. The initial concentrations in soil of anthracene and pyrene were 86.3 and 74.1 mg/kg,respectively, while their remaining concentrations were 20.1 and 27.1 mg/kg on day 30. In comparison, the respectiveconcentrations in unplanted soil on day 30 were 67.6 and 68.2 mg/kg. Anthracene and pyrene were completely removed from soilplanted with butterfly pea and yam bean on day 75. In comparison, 17.8 and 18.2 mg/kg of anthracene and pyrene, respectively,remained in unplanted soil on day 75. Neither anthracene nor pyrene accumulated in any of the plant tissues examined during thestudy, so the mechanism for enhanced anthracene and pyrene removal was the stimulation by these plants of competentindigenous microorganisms to degrade the PAH compounds. |
