Abstract

ne heavy metal, which is potential as pollutant, is cadmium that has been accumulated in soil and sediment. Although, cadmium is non essential element for plants, it is easily adsorbed and accumulated by various plants. The negative effect of cadmium on plants is that it can prevent the absorption of nutrition so that the plant growth will be inhibited and then the plant will die. Therefore, it is necessary to reduce the concentration of cadmium to be used as good growth media. Several methods of heavy metal accumulation, such as physical, chemical and biological methods, have been used, but the three methods have been considered as less effective methods. The use of plants to accumulate heavy metals in polluted soil is considered as a good method because the method is a safe method and can increase the soil fertility. In this research, accumulation of cadmium has been conducted by using Ipomeae reptans Poir. Result showed that the highest concentration that can be accumulated by I. reptans Poir was 3317.68 mg/kg of dried mass with the plantation time of 21 days. The increase of concentration in the growth media increased the cadmium concentration accumulated. The high accumulation of cadmium showed that I. reptans Poir is a hyperaccumulator plant for cadmium. The bioconcentration value was higher than 1, whereas the translocation factor was lower than 1 indicating that the accumulation mechanism was phytostabilization.Keywords : cadmium, accumulation, analysis, Ipomoae reptans Poir.

Abstract

Research on phytoaccumulation of Ni and Zn in Nypa fruticans plants at Tallo River has been done to know the capability of Nypa fruticans for accumulating Ni and Zn. Water, sediment, and plant tissue samples were taken at five stations on the Tallo River using a cutting tool and pipe paralon. Sediment was digested with concentrated HNO3 while plants tissue using HNO3 6M, then analyzed by ICP EOS Shimadzu 9000. The results showed the average concentration of Ni inside part of the plant from station 1, 2, 3, 4 and 5 in order following 21.759,03 ppm, 19.056,03 ppm; 36.806,25 ppm; 10.736,66 ppm dan 13.849,25 ppm. Average concentration of Zn inside the plant from station 1, 2, 3, 4 and 5 in order following 1.319,60 ppm; 1.362,93 ppm; 2.053,46 ppm; 1.591,60 ppm; dan 1.474,09 ppm. Accumulation of Zn and Ni in Nypa fruticans is grouped as hyperaccumulation plant because the ability of accumulation Ni bigger than 10.000 mg/kg and hyperaccumulation towards Zn because able to accumulate Zn bigger than 10 mg/kg. BCF and TF value show that Nypa fruticans naturally able to be used as an phytoremediation plant towards Ni and Zn, especially phytoextraction and rhizofiltration.
