Abstract. The issue of mercury pollution in Aceh waters, Indonesiadue to gold mining activities hasbeen a polemic in local media and Aceh Local Government and the communities have much concern on this case. The impact of mercury pollution in the Teunom and Tangse (Aceh)rivers was often assumed that it has similarity with Minamatapollution in Japan. This article intends to enlighten the characteristic mercury either as elements or compounds including methyl mercury which is highly toxic. Gold mining using elemental mercury is poorly soluble in water, the solubility is only 0.06 g per ton of mercury but the solubility can increase indark the sea-bed and ina lot of dissolved oxygen. Based on the properties of solubility, it is understood that the mercury levels in the Teunom and Tangse rivers still below the tolerance limit, but the gold mining activities still bringsthe risk of environmental damage especially inadequate supervision. Many researchers were trying to prove the natural conversionfrom mercury into methyl mercury (biomethylation) but they usedthe salt instead of the elemental mercury in their experiments. Methyl mercury is found in nature, but the process mercury conversion into methyl mercury compound is still controversial and it has not obtained adequate evidence for the natural alteration,therefore gold pollution which is due to releasing elemental mercury into environment might not be analogue to Minamata case.Keywords: Aceh; Methyl-mercury; Minamata; Mining; Gold Abstrak. Informasi pencemaran merkuri di perairan Aceh dan kaitannya dengan aktivitas pertambangan emas telah menjadi polemik sehingga menjadi perhatian Pemda Aceh dan Masyarakat. Dampak pencemaran merkuri di Sungai Teunom dan Tangse sering dianalogikan dengan kasus pencemaran merkuri di teluk Minamata, Jepang. Artikel ini bermaksud memberi pencerahan kharakteristik merkuri baik sebagai unsur maupun sebagai senyawa seperti metil merkuri yang sangat beracun. Penambangan emas menggunakan unsur merkuri yang sukar larut dalam air, kelarutannya hanya 0,06 g per ton unsur merkuri  namun kelarutannya dapat meningkat jika di dasar laut yang gelap dan banyak oksigen terlarut. Berdasarkan sifat kelarutannya, dapat dipahami bahwa kadar merkuri di Sungai Teunom masih di bawah batas toleransi, namun aktivitas penambangan emas tetap saja memiliki resiko kerusakan lingkungan apalagi jika tidak mendapat pengawasan yang memadai. Banyak peneliti berusaha membuktikan perubahan merkuri menjadi metil merkuri (biometilasi) tetapi mereka menggunakan garam merkuri dan bukan unsur merkuri dalam ekperimen mereka. Metil merkuri memang ditemukan di alam tetapi proses perubahan dari senyawa merkuri menjadi metil merkuri masih diperdebatkan dan belum diperoleh bukti yang kuat perubahan dari unsur merkuri menjadi metil merkuri dalam air sehingga di Peraian Aceh belum tentu tercemar metil merkuri sebagaimana kasus Minamata.Kata kunci: Aceh; metil-merkuri; minamata; penambangan; emas

The Impact

Natural resource management that does not pay attention to the principles of conservation of natural resources and the environment will have negative implications for environmental sustainability. With the discovery of gold on the coast of Tamiouw Village at this time, residents' activities have shifted to gold mining activities in the coastal area of Tamilouw. This study aims to determine the impact of gold mining on the physical environment in Tamilouw Village, Amahai District, Central Maluku Regency, as well as to determine the impact of gold mining on the social and economic environment of the local community. The research  was  conducted  using  non-experimental  methods,  namely exploratory descriptive,  field observations  and literature study. The results showed that gold mining carried out in Tamilouw Village uses mercury in the process of separating gold from sand, although there are also some people who carryout traditional processing. What some people are worried about is that the disposal of mercury waste is not carried out according to the required procedures, so that it will have an impact on environmental damage. The existence of mining activities does not affect the social aspects, namely education, health and age and gender; while from the economic aspect, it also contributes to increasing people's income.

Abstract   Exploitation of natural resources through unlicensed gold mining (PETI) is not in accordance with mining operational standards occurring along the Noeltoko River, West Miomaffo Subdistrict, Timor Tengah Utara Regency, East Nusa Tenggara Province resulting in damage and environmental degradation. Changes and environmental damage include the formation of dug holes around the river flow, turbidity of water, changes in river flow. Other problems that arise are conflicts between these PETI workers and with other communities. This community service activity aims to provide an understanding to the community about the importance of maintaining and caring for rivers from excavation in the river walls that can cause debris / landslides explaining the impact of the use of hazardous materials such as mercury / mercury and cyanide, socialization of regulations regarding the formation of People's Mining Areas (WPR) ), introducing "sluice box" equipment to help the process of separating gold sand from sand. This activity was supported by the UPT ESDM Atambua Branch and was followed by 40 people who used to mine on the Noeltoko river. It is expected that the guidance and assistance can raise public awareness to be able to mine but still preserve the environment   Keyword: PETI, Noeltoko, WPR, sluicebox,   Abstrak   Eksploitasi sumber daya alam melalui Penambangan Emas Tanpa Izin (PETI) tidak sesuai dengan standar operasional penambangan terjadi di sepanjang sungai Noeltoko-Kecamatan Miomaffo Barat, Kabupaten Timor Tengah Utara Propinsi Nusa Tenggara Timur yang mengakibatkan kerusakan dan penurunan kualitas lingkungan.

Decay Series

NORM is a material containing radioactive elements that exist naturally. All minerals and raw materials contain radionuclides from nature, most important for radiation protection purposes are the U-238, Th-232 and K-40 decay series. This element naturally grows and is considered a major contributor to the annual individual background radiation dose. Therefore, each individual can be exposed to NORM through various activities they do, one of which is gold mining activities. Gold mining in addition to causing exposure to NORM, is believed also can cause significant environmental damage. This study aims to determine the index of radioactive risks that resulted from gold mining activities in the batang kuantan river. The sample used for this research is soil from batang kuantan river which then analyzed using gamma ray spectrometry. The results show that the index of radioactive risk value indicated by all soil samples in the batang kuantan river is still below the predetermined maximum limit value.

The Impact

The impact of artisanal mining on livelihoods in developing countries is a contentious issue. As a contribution to this subject, the study assessed the implications of artisanal gold mining activities on smallholder agriculture in the Wa East District of Ghana. A descriptive survey design with a mixed methods research approach was used. Primary data were sourced from respondents through interviews, questionnaire administration, and field observation. Five artisanal mining communities were selected based on the intensity of mining activities in them. The study respondents consisted of 290 household heads drawn randomly from 1,050 households. Also, key informants consisting of 5 assembly members and 15 lead artisanal miners were interviewed. The study found artisanal mining to be a dominant livelihood strategy in the district, employing about 76.2% of respondents at various levels. Artisanal mining contribution to household income was higher than food crop farming. Proceeds from mining are used to finance smallholder agriculture. However, the activities of the miners have resulted in the degradation of farmlands. We argued that artisanal mining activities should be aligned with other livelihood options such as agriculture in local communities. The study called for the engagement of local miners and traditional rulers in mineral resource decision-making.

The Impact

The construction of major marine works is frequently associated with the need to relocate large quantities of material. Relocation at sea is associated with a number of environmental impacts. For non-contaminated silty/clay material main environmental effects include blanketing of the sea bed and increase in turbidity, or reduction in the clarity of water. Blanketing of the sea bed has a harmful effect on the marine life whose ability to recolonise the new material is doubtful. The importance of marine life can be evaluated in relation to the number of species and specimens living on the sea bed. Measurements reveal that there is a reduction in the number of species with increase in depth. The dumped material that covers the sea bed, and therefore affects adversely the marine life, has less impact the greater the water depth. The increase in turbidity, associated with the suspended soil material in the water, although temporary, it nevertheless has a potential impact on the tourist industry. Places which are popular with tourists because of the clarity of their waters, might have adverse publicity if the turbidity increases to noticeable levels. Turbidity levels depend on the current direction and speed, the rate of mixing (dispersion coefficient), the size and density of the dumped material and the method of dredging and disposal. Predictions of expected turbidity levels can not therefore be made with accuracy or great confidence if the above parameters are not well known. Sensitivity analyses can however be made in order to predict the range of values of the expected turbidity levels. The impact on marine life and the increase of turbidity can be reduced by dumping the dredged material in deep water and at great distance from bathing beaches. This measure is associated with adverse financial implications. The optimum relocation site is one at which the total cost of both the environmental damage and the relocation cost is minimum.
