ABSTRACT
This study tested the potential of swamp cabbage (Ipomoea aquatica Forsk) as a phytoremediator of lead. It specifically determined the amount of lead in water, roots, and stem of swap cabbage before and after phytoremediation after being exposed for ten days. It further determined the significant differences in the amount of lead in water. roots and stem of swamp cabbage before and after such process.
Artificial lead contaminants were placed in five sampling culture vessels each containing four liters of ground water. Each culture vessel contained five replicates. The plants were placed in the culture vessel and were set to be exposed to the lead contaminant in a duration of ten days. On the tenth day, the replicates were removed and were macerated. The lead content present in the extracts were measured using the lead lode probe.
Results showed that there was no significant difference in the amount of lead before and after the ten-day phytoremediation process.
