| Summary: | Phytoremediation in plant system functions to degrade, extract or inactivate potentially hazardous compounds
in contaminated soil, air or water. Phytoremediation involves different mechanisms such as phytodegradation,
rhizodegradation, phytoextraction or phytostabilisation. Therefore, this study aimed to assess four terrestrial
fern species to sequester heavy metal contaminants from laterite soil. Samples were taken from 3 different
localities in Perak, Selangor and Johor to investigate their heavy metal sequestration rate stability and pattern
distribution in this highly weathered soil. 10 heavy metals were measured using ICP-MS (Perkin Elmer
NexION 300X). Al and Fe were detected with a high concentration at most of the sites with different volume of
concentration. The analysis of variance (ANOVA) established highly significant differences (P<0.0001) for all species of ferns and all interactions. Since there are many factors that contribute to the heavy metal accumulation, plant species can be one of the alternative measures to remediate soil heavy metal contaminants. Thus, this green technology can be a relatively cheap treatment for other heavy metal contamination sites such as landfill area. |
