The aims of this study were to investigate the impact of traditional mines on environment and forage in Lombok Island. The study was conducted in 2013 on forage, water and soil in 26 villages around the mining site in west Lombok and central Lombok Regency. The result shows that mercury contamination was detected from some location being investigated. The percentage of villages that have mercury contamination was detected in 72% location and water contamination with cyanide detected in 66.7% location. Furthermore, the level of mercury in the soil has exceeded the allowable threshold as well as the content of cyanide in water. In forage samples obtained, there was approximately 0.05 ppm of mercury found in 7.7 % of locations. The extent of mercury and cyanide contamination in environment can provide a low exposure to the surrounding communities and livestock it needs further awareness to anticipate of hazard on human and livestock health.
