EDTA is used in soil remediation because of its ability to move metal in the soil matrix. EDTA solutions can dissolve heavy metals including Pb. Codiaeum varigatum is an ornamental plant in addition to having a high aesthetic, ecological and economic value. In this study analyzes the effect of EDTA on the growth and accumulation of metals in C.varigatum plants. The purpose of this study was to analyze the effects of EDTA on growth, photosynthetic pigment content and Pb accumulation in C.varigatum plants. Pot experiments using C.varigatum with lead 500 Pb kg-1 soil and different levels of EDTA (mM) 5,10and 20. The parameters studied included plant biomass, Pb accumulation in plant and photosynthetic pigment content measured after 30 days. The results showed that EDTA concentration of 20 mM caused an increase in Pb accumulation and a decrease in plant biomass and photosynthetic pigment content. © 2019 IOP Publishing Ltd.
