Abstract:

Heavy metal contamination has become a global problem, especially in the developing countries. The objective of this research was to analyze the content of mercury heavy metal in river water surrounding gold mines in North Sumatera. The samples of water were taken from twelve stations in the vicinity of gold mines in North Sumatera. Determining mercury in the water was done by using Atomic Absorption Spectroscopy (AAS). Pollution status was determined through the calculation of Hg ratio in water samples. The result of the research on the canal water indicated that Hg heavy metal value concentration was under the acceptable threshold according to the Decree of the Minister of Environment No. 115/2003 so that it can be used for its purpose based on SNI (6989.78: 2011). It is recommended that the people in North Sumatera who reside by the rivers use water often for their daily needs such as taking a bath, washing, fishing, and so on. The risk for health problems for the people who reside by rivers can occur when the polluting status of mercury water is affected by amalgamation process units.
