“…Heavy metal mercury is easily soluble and changes the stability of the carbonate form to hydroxide, which forms particulate bonds in the waters. Then precipitation occurs and ends in the formation of mud [19][20]. Mercury metal is not easily detected.…”

This study aims to determine the mercury accumulation in Gerris sp and its potential as a bioindicator. This type of research is experimental research. This research was conducted at Lake Taliwang and the UGM Integrated Research and Testing Laboratory. The sampling point in this study was determined based on the distance to the pollutant source. It was divided into station 1 (inlet), an area close to the pollutant source, and station 2 (outlet), far from the pollutant source. There are 3 test tests: the accumulation of mercury in water and sediment, mercury in the gerris, and the gerris as a bioindicator of mercury pollution. Analysis of the test results data is presented in descriptive statistics. The results of this study are (1) The waters of Lake Lebo are polluted by mercury, found in sediments and water, and enter the food chain, namely gerris. The mercury concentration in the inlet area is greater than the outlet area because it is closer to the pollutant source (2). Gerris can be used as a bioindicator of mercury pollution in Lake Lebo Taliwang because it can accumulate heavy metals. It meets the criteria of bioindicator organisms and is very strongly correlated with water. The finding suggests that the local government makes regulations regarding mercury metal pollution in Taliwang Lake because mercury metal can enter other food chains and is toxic to living things.

“…What are the real effects of illegal mining on the environment and public health? To answer this question, we added quantitative data for our sample sites, drawn from the results of secondary-source studies undertaken in the past ten years at several gold-mining sites in Indonesia [ 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 ]. The environmental impacts and health threats from illegal mining operations can be seen in Figure 7 .…”

Artisanal Small-scale Gold Mining (ASGM) activities, despite offering numerous economic incentives, inflict negative impacts on the environment and public health due to the use of mercury or cyanide. This study aims to compare three ASGM locations in Indonesia in terms of environmental impacts and potential health problems in the community. As part of this research, field surveys at three ASGM illegal locations with different conditions, observations, literature studies, and interviews with the community and stakeholders were conducted. At each of the survey sites, the potential threat to public health due to the use of mercury was determined to be high. Additionally, many of the environmental impacts detected were deemed to have reached a high-alert stage, in some cases even posing a level of extreme danger. Based on these results, it has become clear that a form of mining management which reduces the negative impacts on the surrounding environment and community health is needed. The suggestions put forward in this paper, including the call for greater control of ASGM, may also be applied in other developing countries which suffer from similar problems and conditions.

“…With regard to the latter, the effects of illegal gold mining have the potential to cause environmental damage in the long term, taking the form of negative changes to the landscape, landslides, and erosion, as well as water pollution in/around mining sites. A number of studies have reported upon the contribution of ASGM to land degradation [ 19 , 42 , 75 ], river water pollution [ 18 , 74 , 76 , 77 ], and soil/sediment pollution [ 18 , 25 , 26 , 36 , 57 , 78 ], whose conditions do not meet established quality standards. Indonesia Government Regulation 82/2001 for mercury in river water is 0.002 mg/L and in drinking water or in the water supply it is 0.001 mg/L.…”

Indonesia is host to a long history of gold mining and is responsible for a significant contribution to world gold production. This is true not only with regard to large gold mining companies but also to small-scale mining groups comprised of people and enterprises that participate in the gold industry of Indonesia. More than two thousand gold mining locations exist in present day Indonesia. Artisanal and small-scale gold mining (ASGM) sites are spread out across thirty provinces in Indonesia, and have provided work opportunities and income for more than two million people. However, the majority of ASGM activities use rudimentary technologies that have serious impacts upon the environment, public health, and miners’ safety, which in turn generate socio-economic impacts for people residing around the mine sites. Moreover, many ASGMs are not licensed and operate illegally, meaning that they are immune to governmental regulation, and do not provide income to the regions and states via taxes. The possibility for more prudent management of ASGM operations could become a reality with the involvement and cooperation of all relevant parties, especially communities, local government, police, and NGOs.
