Abstract
Ludwigia adcendens and Ludwigia grandiflora are water weeds rapidly grow and disperse. The root of these plants can take nutrients up from waters, filter and absorb dissolved solids, and as growth base of microbes. The objective of this study was to test the efficiency L. grandiflora and L. adcendens in remediating cadmium (Cd). These plants were acclimatized first in hydroponic for 14 days, then moved to medium with varying treatments; only L. grandiflora, only L. adcendens and combination of both species at different Cd concentration (0, 5, 10, and 15 ppm). Level of Cd was analyzed at 7th and 14th day using Atomic Absorption Spectrophotometer (AAS), while wet biomass of each group was compared. Data collected was analyzed statistically. Efficiency as Cd phytoremediator from low to high was found to be L. grandiflora, L. adcendens > combination of both species, in which bioconcentration factor (BCF) > 1 and translocation factor (TF) < 1. Wet biomass growth also supported these plants as Cd phytoremediator; plants with higher Cd accumulation had yellow leaves compared to plants accumulated lower Cd level. Concentration of Cd was also found to be higher in the roots than in plant leaves.
