1) Phytoremediation-the use of plants for the in situ treatment of contaminated soil and water-has recently emerged as an inexpensive and user-friendly alternative to traditional methods of environmental clean-up. The present article outlines the characteristics of phytoremediation based on accumulated research evidence, along with discussions on its advantages and disadvantages. It further reviews various mechanisms involved in the phytoremediation processes: phytoextraction, rhizofiltration, phytostabilization, phytovolatilization and phytodegradation. Along the way, the author summarizes examples of its applications to environmental pollution control. These include wastewater treatment, removal of heavy metals, and hydrocarbons, remediation of recalcitrant contaminants, phytoremediation of radionuclides, and application of transgenic plants for enhanced biodegradation and phytoremediation. The remainder of the article briefly concludes with directions for future research.

“…The previous study shows successful remediation of EGs by E. cordifolius and focuses on the potential of the plant in EGs removal in different molecular weights (Teamkao and Thiravetyan 2010). However, one concern about using plants to remediate organic contaminants is that it may produce a more toxic compound than the original.…”

Mono-, di-, and triethylene glycol are chemicals used in various industrial (polyester products, plasticizers, printing, etc.) and domestic settings. The toxicity of these compounds is relatively low, but they do pose risks to the environment. Phytoremediation of the three glycols by Echinodorus cordifolius L. Griseb. were studied. The glycols were degraded in the leaves and roots, but leaves were the main source of degradation. The results of this study indicate that the plant can degrade triethylene glycol to diethylene glycol, diethylene glycol to 1,4-dioxan-2-one, or even further to monoethylene glycol. Moreover, 2-methoxy-4-vinylphenol, 1,2-cyclopentanedione, 1,4:3,6-dianhydro-.alpha.-d-glucopyranose, 2-propenamide, and 2,5-anhydro-1,6-dideoxyhexo-3,4-diulose were produced by this plant in response to the glycols.

“…For example, monoethylene glycol, which has a smaller molecular size, could be taken up by Echinodorus cordifolius more rapidly than diethylene glycol and triethylene glycol, which have higher molecular sizes. Meanwhile, the symptoms at the leaf margins appeared more rapidly after exposure to MEG than DEG and TEG (Teamkao and Thiravetyan 2010). Sriprapat and Thiravetyan (2013) reported the effect of molecular weight of benzene, toluene, ethylbenzene, and xylene (BTEX) on Zamioculas zamiifolia.…”

Our screening of plants showed that Cyperus alternifolius (Umbrella papyrus) had the highest efficiency removal in real wastewater containing monoethanolamine-higher than Echinodorus cordifolius (Creeping Burrhead), Thalia geniculata (Alligator Flag), Acorus calamus (Sweet Flag), and Dracaena sanderiana (Lucky Bamboo). Therefore, this research studied the degradation of monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) by C. alternifolius. Plants could degrade TEA into DEA, then into MEA, and then further into acetic acid. The accumulation of ethanolamines was found mainly in plant stems, which had the highest biomass. This demonstrated that the molecular size is closely related to a diffusion coefficient that affects the removal rate through plant bodies. A smaller molecular weight-MEA (MW = 61.08 g mol(-1))-was taken up the fastest, followed by DEA (MW = 105.14 g mol(-1)) and TEA (MW = 149.19 g mol(-1)), the highest molecular weight. The plants' toxicity when exposed to ethanolamines elucidated that MEA had the highest toxicity, followed by DEA and TEA. In addition, the application of C. alternifolius in monoethanolamine-contaminated wastewater revealed that plant could completely uptake MEA at day 5 from an initial MEA concentration of 18 mM. The result indicated that C. alternifolius has the potential to remove ethanolamines and can be applied to ethanolamine-contaminated wastewater.
