“…5 and 6). Similar results were obtained by Halder et al 49 who stated that the accumulation of K among the vegetable parts was higher in the stems (ranged from1.64 ± 0.04% to 9.96 ± 0.04%) as compared to in the leaves (ranged from 0.14 ± 0.02% to 4.39 ± 0.01%). However, the distribution of Fe in the plant obtained in the present work contradicted with Olowu et al 50 who stated that leaves had a higher Fe content as compared to stems.…”

Phytoremediation is one of the environmental-friendly and cost-effective systems for the treatment of wastewater, including industrial wastewater such as palm oil mill effluent final discharge (POME FD). However, the effects of the wastewater on the phytoremediator plants, in term of growth performance, lignocellulosic composition, and the presence of nutrients and heavy metals in the plants are not yet well studied. In the present work, we demonstrated that POME FD increased the growth of P. purpureum. The height increment of P. purpureum supplied with POME FD (treatment) was 61.72% as compared to those supplied with rain water (control) which was 14.42%. For lignocellulosic composition, the cellulose percentages were 38.77 ± 0.29% (treatment) and 34.16 ± 1.01% (control), and the difference was significant. These results indicated that POME FD could be a source of plant nutrients, which P. purpureum can absorb for growth. It was also found that the heavy metals (Al, As, Cd, Co, Cr, Ni and Pb) inside the plant were below the standard limit of the World Health Organization (WHO). Since POME FD was shown to have no adverse effects on P. purpureum, further research regarding the potential application of P. purpureum following phytoremediation of POME FD such as biofuel production is warranted to evaluate its potential use to fit into the waste-to-wealth agenda. Pollution of soil and water caused by wastewater is one of the major global threats that our environment is facing today. One of the wastewater source is palm oil mill effluent final discharge (POME FD), which is a by-product of palm oil extraction process. Since Malaysia is the world's second largest producer and exporter of palm oil, thus, a large amount of POME is generate annually 1. It is estimated that for every tonne of crude palm oil produced, about 2.5 to 3.5 tonne of POME is generated 2. POME is considered as the main source of water pollution in Malaysia due to the high biochemical oxygen demand (BOD) and chemical oxygen demand (COD) that causes a reduction of the biodiversity and ability of aquatic ecosystem 3,4. Furthermore, the damages to the river cannot be undone easily. Since POME is generated in huge amounts at a time, it is very difficult to manage, and the treatment of this wastewater is expensive. Consequently, the cheapest and easiest way for this wastewater disposal that have been practiced in Malaysia is by discharging the treated POME to the nearby river or stream 2,5,6. However, Madaki and Seng 7 noted that even treated POME (POME FD) still poses adverse effects on the environment; an observation also supported by the findings of Ibrahim et al. 8. This is due to it still containing significant amount of organic matter. For that reasons, Ujang et al. 9 has decided to further treat the POME FD using Napier grass constructed wetland in a process called phytoremediation, and thus, achieved 71.57% of COD and 83.59% of total suspended solid (TSS) reduction. Phytoremediation is a process where plant naturally degrade, remove, or immobilize ...
