| Summary: | Conventional (static) phytoremediation system has been used widely, however dynamic system is developed to deal with spatial efficiency. This study was conducted to clarify the effectiveness of two phytoremediation systems in reducing Pb concentration from medium, to quantify Pb bioaccumulation in plant organs (root, stem, and leaf), and to measure translocation rate in plant model (water spinach, Ipomoea aquatic L.). Six individuals seedling of water spinach (average biomass 53.71 mg) were planted in 10 L containers with two different systems (static, S and dynamic, D) and two Pb concentration i.e control (0 ppm, S0 and D0) and 50 ppm (S50 and D50 ppm). Biomass and Pb concentration in root, stem, leaf, and medium were measured every five days. Atomic absorption spectrophotometry (AAS) was used to measure Pb concentration both in plant and medium. Translocation factors (TF), bio-concentration factors (BF), and metal extraction ratio (MER) were calculated to observe Pb translocation and the ability of water spinach to extract metal from environment. Biomass in both systems are smaller in high Pb concentration than control. Lead is accumulated more in leaves, follows by roots, and stems. Dynamic system shows high reduction of Pb in medium (46%) than static systems (34%), thus the dynamic system can be recommended to reduce lead from aquatic ecosystem. TF for both systems are 1.69 (S50) and 2.69 (D50); BF are 6.51 (S50) and 10.8 (D50); and MER are 0.19% (S50) and 2.4% (D50), respectively. These parameters show that water spinach can be applied for phytoremediation model.
