Abstract

Along with the discovery of several gold prospects area in ​​Central Sulawesi, gold mining had increased both by companies, cooperatives and illegal mining. The activity of this mining produce waste that consist of hazardous toxic substances in which there was a heavy metal such as mercury (Hg). This metal is one of the trace elements that has liquid at room temperature, high specific gravity and power electric conductivity, and a toxic chemical element became a global concern because has significant hazardous effect on human health, wildlife and ecosystems. This study was  aims to know the content of mercury in soil around the Poboya’s gold mining. The method used in this study was a survey which describes the actually condition of this area and assess the causes of certain symptoms. In this study measurements, field observations, and laboratory analysis had been done. There step that be noticed in this survey were pre-survey, main survey (sampling) and laboratory analysis. Compose soil sample for laboratory analysis had been collected from several sample point that had been plotting by tactics. The results of this study showed that the content of mercury in all representative soil sample and tailings had highest than threshold. Normally, concentrations of mercury in the soil range from 0.03 ppm (normal) to 0.3 to 0.5 ppm (critics); while concentrations of mercury in soil agricultural areas ranged from 0.057 ppm to 8.19 ppm and in tailings ranged from 84.15 ppm - 575, 16 ppm.

Abstract

Penambangan emas di Desa Poboya merupakan salah satu wilayah pertambangan emas rakyat yang ada di Kabupaten Sigi-Biromaru. Kegiatan penambangan tersebut dilakukan oleh sekelompok masyarakat dan menggunakan cara-cara penambangan yang sangat sederhana (tradisional). Penambangan yang dilakukan mengakibatkan lingkungan menjadi rusak.  Logam berat merupakan istilah yang digunakan untuk unsur-unsur transisi yang mempunyai massa jenis atom lebih besar dari 6 gcm-3. Merkuri (Hg), timbal (Pb), tembaga (Cu), kadmium (Cd) dan stronsium (Sr) adalah contoh logam berat yang berupa kontaminan yang berasal dari luar tanah dan sangat diperhatikan karena berhubungan erat dengan kesehatan manusia, pertanian dan ekotoksikologinya. Lingkungan yang terkontaminasi oleh merkuri dapat membahayakan kehidupan manusia karena adanya rantai makanan.  kontaminasi merkuri pada tanaman  harus ditempatkan secara khusus dan ditangani secara hati-hati.  Penelitian ini dilaksakan dengan tujuan untuk mengetahui kandungan merkuri di kawasan pengolahan tambang emas Poboya.  Metode penelitian yang digunakan dalam penelitian ini adalah metode survey yang menggambarkan/menguraikan sifat dari suatu keadaan lokasi secara aktual dan mengkaji penyebab dari gejala-gejala tertentu. Dalam penelitian ini dilakukan pengukuran, pengamatan  dilapangan dan pengkuran laboratorium, pra survei, survei utama (pengambilan sampel) dan analisi laboratoruim, dengan pengambilan sampel secara taktis.  Hasil penelitian menunjukkan bahwa kandungan merkuri (Hg) pada sampel yang mewakili lokasi penelitian adalah tidak semua sampel tanaman menunjukan kandungan merkuri melewati ambang batas berdasarkan acuan Alloway, (1995) Konsentrasi merkuri (Hg) dalam tanaman kacang tanah berkisar 0.098 ppm- 0.45 ppm, pada tanaman jagung berkisar 0.07 ppm sampai 0.43 ppm, pada tanaman padi berkisar 0.03 ppm - 0.21 ppm dan pada tanaman bawang merah berkisar 0.01 ppm - 0.32 ppm. Kandungan logam berat merkuri (Hg) dalam tanaman di areal kelurahan Poboya masih dalam ambang yang bisa di toleransi namun menghawatirkan.
