ABSTRACT

The capability of Sansevierialiberica to withstand crude oil pollution, degrade and/or accumulate the contaminant was investigated using 0.3, 1.3 and 6.3% v/w concentrations of crude oil to pollute soil vegetated with the stem cuttings of the plant. These treatments were repeated in unvegetated soils and the control had no crude oil pollution. The experiment was carried out in 3 replicates in a completely randomized design. Total Petroleum Hydrocarbons (TPH) were determined for all soil samples (vegetated and unvegetated)as well as the leaves, stem and roots using Gas Liquid Chromatography (GLC). Vegetative parameters namely; number of leaves, leaf area, plant height and stem circumference were determined for both control and polluted plants before and after pollution.
