title: Phytoremediation of Mono-, Di-, and Triethylene Glycol by Echinodorus cordifolius L. Griseb.
abstract: 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.
