Research Journal of Ecology and Environmental Sciences | Vol 3, Issue 1

Figure A1

Comparison of the Performance of <i>Costus</i><i> </i><i>afer</i> Plant at Different Ages over Time in Crude Oil-Contaminated Soil (in terms of TPAH reduction). 【T<sub>1</sub> = 1 week old, T<sub>2</sub> = 2 weeks old, T<sub>3</sub> = 3 weeks old, T<sub>4</sub> = 4 weeks old, T<sub>5 </sub>= 5 weeks old, and T<sub>6</sub> = 6 weeks old Plants; C<sub>1</sub> = Low Contamination Level; C<sub>2</sub>: Medium Contamination Level; C<sub>3</sub>: High Contamination Level; C<sub>4</sub>: Medium Contamination without Treatment (Control); Error bars on chart are standard errors】
