Mercury and Chromium Distribution in Soil Near Maros Karst Ecosystem

The legal karst protection in Indonesia seems unclear where karst is still seen as a resource that can be utilized, not as an ecosystem that must be preserved. In this study, a total of 20 soil samples were collected around industries and abandoned mine of Maros Karst Ecosystems. Quantitative assessment is done by measuring the factor of single element enrichment and potential biological effects on living things. Calculated Hg accumulation indicates that soil conditions in the area around the Karst Maros Ecosystem have been polluted. In contrast, Cr accumulation means the soil condition remains unpolluted and not harmful.
