This research was conducted to investigate the potential use of leachate and compost for
phytoremediation of divalent mercury polluted soil by Jatropha. Greenhouse experiment was carried out for two
months and replicated twice. Mercury concentration in soil was in the range of 1 to 20 mg Hg/kg soil. It was
found that the mercury concentration in soil without significant negatif effect towards Jatropha was no more
than 6 mg Hg/kg soil. The levels of leachate and compost, which were added to the soil, were no effect on
phytoremediation efficiency. However, both of materials were significantly effective to be used for
phytoremediation using Jatropha.
