N2 - Mercury waste from illegal mining was dumped into the Tiabo river body. Measurements of mercury concentrations in sediments have been carried out using purposive sampling methods in upstream, midstream, and downstream in 2019 and 2021. The sediment samples were analyzed using Atomic Absorption Spectroscopy using US EPA Method 200.2 1994. The Tiabo river in 2019 and 2021 was moderately polluted and unpolluted, respectively. The decreasing mercury concentration every year is due to the elimination of mining activity since 2020 by the government and the location of the hydrodynamics of the river. The Tiabo River is a river that has a strong current, so it is very likely that mercury in the water is carried away by currents Based on the results of the sediment test in 2021, no mercury was detected in the Tiabo river sediment. It is due to the mercury concentration in the sediment from the river current to the open sea.
