Polusi lingkungan akibat kegiatan penambangan dapat dikurangi dengan fitoremediasi. Cyperus kyllingia adalah salah satu tanaman hyperaccumulator yang dapat mengurangi kadar logam berat seperti Hg di Desa Sekotong Tengah, Kecamatan Sekotong, Kabupaten Lombok Barat. Penelitian ini dilakukan dengan menanam C. kyllingia dalam polybag 5 kg dengan perbandingan 70%: 30% tanah dan tailing emas. Tailing emas dibagi menjadi dua jenis, Sianidasi (T1) dan Amalgamasi (T2). Pada 53 DAP, ligan natrium sianida (NaCN) ditambahkan dengan 2 ligan berbeda, 4g dan 8g dalam tanah. Cyperus kyllingia menyerap 89,97 mg / kg Hg pada kanopi dan 78,21 mg / kg Hg pada akar. Penambahan ligan Natrium sianida (NaCN) dapat meningkatkan penyerapan Hg oleh C. kyillinga. Penyerapan Hg pada tanaman dengan penambahan ligan lebih tinggi daripada tanaman tanpa penambahan ligan.References
