Research Abstract |
Mercury contamination caused by Artisanal and Small-scale Gold Mining (ASGM)was investigated at 10 districts in 9 provinces of Indonesia, in which small scale gold mining activities haveconducted intensively.Investigation was carried out at Pobaya mining area in Palu city of Central Sulawesi province because Pobaya mining area was thought to be the worst contaminated area due to the concentrated mining facilities.The health of the people was at risk because of extremely high concentration of gaseous mercury in addition to the fishery activities in the Palu bay into which waste water contaminated by mercury from ASGM flew.The dating of the core samples of the sediments obtained from a lake in the central Kalimantan revealed that the mercury contamination in the sediments had increased since 1983.The total amount of mercury emission to the environment estimated was much larger than that reported by UNEP
