| Abstrak | Some plant species growing in the contaminated areas, indicated high tolerancen and potentially affective in accumulating pollutants in their roots and above ground portions. These plants can be utilized as hyperaccumulators for cleaning up the contaminated sites. Study on heavy metal and CN contamination and potential plant species for accumulator is urgently needed in order to understand the problems and to obtain suitable technology for the solution. This research aims to examine CN accumulator plants growing in CN contaminated tailing to find a possible solution of cleaning up by using green technology of phytoremediation. Phytoremediation is defined as clean up of pollutants primarily mediated by photosynthetic plants. This study aims to characterized plants that grow under extreme contaminated media of gold mined tailing and to analyse their potencies as hyperaccumulators. Mikania cordata (Burm.f) B.L.Robinson,Centrosema pubescens Bth and Leersia hexandra Swartz which proven tolerant and dominant in the contaminated site were examined in this research. The plants were grown in tailing waste media added by 0 ppm CN, 2.5 ppm CN, 5 ppm CN dan 7.5 ppm CN using complete randomized design with 5 replicates. The results showed that the plants were capable of growing under the highest level of CN. Among three species, Mikania cordata showed the highest biomass production followed by Centrosema pubescens and Leersia hexandra. Total CN accumulation varied between species, the highest was reached in 2.5 ppm CN treatment i.e. 22.48 mg/kg in Leersia hexandra, followed by Centrosema pubescens (18.92 mg/kg) and Mikania cordata (12.03 mg/kg). The highest CN content was 0.085 mg in Mikania cordata treated with 7.5 ppm CN. High ratio of shoot to root CN (>1) was expected in hyperaccumulator plants to indicate that CN was more distributed in the above ground portions than in the roots. In this study the highest shoo to root CN ratio was showed in Mikania cordata i.e.11.75. |
