Abstract

People's gold mining in Sekotong, also known as Unlicensed Gold Mining (PETI), causes environmental pollution problems because located at the surrounding community processes gold using the amlagamation technique with the help of mercury (Hg) in binding gold. Mercury waste discharged directly into the environment could have adversely affects public health and degrades soil and water quality. The presence of mercury in the soil is strongly influenced by soil characteristics, one of which is soil physical properties. The purpose of this study was to determine the relationship between the physical characteristic ustifluvents Entisol soil of Sekotong soil and mercury content at 0-20 cm soil depth. This research was conducted using descriptive method with survey technique. Soil sampling was conducted at 3 location points near the logs and tailling at a depth of 0 - 10 cm and 10-20 cm, each location point was replicated 3 times. The selection of soil sample points was based on contour differences that affect the proportion of mercury content at each soil depth. The results showed that the highest mercury content was at point 3 with an average value of 0.3089 ppm and there was a strong to very strong relationship between soil physical properties and Hg content.

Abstract

One of the hazardous wastes generated from unlicensed gold mining is mercury. Mercury is a toxic metal that can have a negative impact on the environment such as reducing soil and water quality and disturbing human health. The presence of mercury in the soil is completely controlled by adsorption-desorption of various sorbents. Soil properties greatly affect the adsorption and desorption of mercury in the soil. Because different soil properties will adsorb and desorb mercury in different ways and amounts.  The purpose of writing this article is to review the results of previous research on the adsorption-desorption of mercury in soil so as to determine the extent of the risk of soil and environmental pollution. The method used in this writing is to collect and process data sources from previous research published in scientific articles, books, and discussion results. The results show that soils with high organic matter, iron oxide and clay content can absorb more Hg2+. In addition, lower pH has more hydroxylated surfaces that can adsorb more Hg2+. Irreversibility was found where the amount released or desorbed was less than the adsorption of mercury.
