This article discusses the socio-cultural consequences of small-scale artisanal gold mining on the archaeological record and other heritage resources at Awudua Dada, located in the Prestia-Huni Valley District of the Western Region, Ghana. The settlement witnessed vibrant commercial exchanges between Wassa and Dutch traders in the mid-seventeenth century because of its abundant gold resources, much of which was exchanged for novel European trade goods such as varieties of alcoholic beverages, guns, gunpowder, and finished metal products among many others. Currently abandoned and desolate, groups of small-scale artisanal gold miners continue to prospect gold there, and along the banks and bed of the Ankobra River which lies close-by. Archaeological, historical, and ethno historical research constituted the principal methods used to derive data for the study which revealed that mining had not only negatively impacted the archaeological record and other cultural resources there but had also caused significant environmental degradation.

<p>Gold amalgamation processes using mercury were practiced in small scale gold mining activities in Krueng Sabee, Aceh Province. Seafood (fish, mollusc, shrimp) and human hair samples were collected to assess mercury concentrations.  Acute and chronic toxicity symptoms which arise among the populations were observed as well as personal protective equipment used by gold miners. The range of mercury concentrations varied among fish, shrimp, and molluscs. The highest mercury levels were recorded in fish <em>Puntius latristriga</em> (172.299 ± 10.626 µg/g wet wt.), followed by mollusc, <em>Polymesoda caroliniana </em> (160,032 ± 0,522 µg/g wet wt.), fish <em>R.kanagurta</em> (149 ±2,000 µg/g wet wt.), shrimp <em>Penaeus monodon</em> (116.975 ± 4.807 µg/g wet wt.).  The variation of mercury concentrations in hair samples of 72 respondents were detected from 5.7 µg/g to 88.1 µg/g. The most frequent acute and chronic intoxication symptoms documented were headache, muscle cramps, cough, and aphthous ulcers. Personal protective equipment which has correlation with high mercury levels in gold miners were respirator/mask, gloves, and apparel (p &lt; 0.05). All seafood samples exceeded 0.5 µg Hg/g MoH Food and Drug Administrasion threshold level and hair samples over 10 µg/g as set by WHO tolerance limit.</p>

Gold deposit at Cineam area is an epithermal gold deposit of low sulphidation type which lies about 180 km southeast of Bandung at an elevation of 400 meter above the mean sea level. The Cineam deposit is administratively belongs to Cineam Subdistrict , Tasikmalaya Regency, West Java Province, which dominantly occurred within volcanic rocks unit of Jampang Formation. Alterations developed in this area namely propylite, argillic, sericitation, and silisification, occurred in andesitic lava, volcanic breccia, and andesitic to dacitic tuff. The thickness of gold bearing quartz veins are commonly from few cm up to > 20 cm, while for the veins of higher grade of gold content the thickness are about 5 cm or less. The average grade of gold content is around 6 - 10 gr/t Au. Although Cineam gold deposits can not be classified as a big scale deposit, itsmineral genesis has an interesting characteristic to be further studied. The Cineam area representing one of the most prospect areas of gold found in the eastern part of West Java Southern Mountain Range. As the Cineam gold deposit is proportionally suitable for a small scale gold mine, the local government had already gave a mining license to a Family Firm in the form of a Village Unit Cooperation or “KUD” such as KUD Mekarjaya which had also been updated to become a B class of Exploitation License category that permitted for the realization of metallic exploitation. This action was in line with the implementation of Autonomy Policy since the year of 2001.Although KUD Mekarjaya’s mining production is relatively so small but in fact the mining activity is still being maintained to be daily earnings for the local gold miners to rely on. Within the long run of the local gold miners activity at Cineam which has been working since 1968, this condition can give rise to many well skilled and experienced labors in seeking for gold ores, in handling small scale gold mining works, and in obtaining for the bullions. In other side, on thecontrary, there are some negative actions must be kept under control such as the disposal of the waste or tailing directly into the river and the unsafely process of heating the amalgam to obtain the bullion including other improper ways done during the handling of their mining activities. Since the whole mining operation so far generally financed by individual investors it is very likely that small scale gold mining lacks of the capital needed for the mining operation. This condition is what the KUD always facing with so that management and financial matters can be a very serious problem affecting the progress of the KUD Mekarjaya From some presentation given by the CCOP-CASM Meeting in Bandung we can compare the condition of small scale mining in Indonesia. and that from other countries which have conducted good management in mining regulation and policy in relation with licensing, mining workers, tax payment and awareness of environment live in the vicinity of mining areas On account of that event this can be expected to motivate and encourage the policy anddecision makers either locally or centrally throughout Indonesia in giving more attention related to the guidance, monitoring and inspection of the implementation of small scale mining activities which is actually growing in numbers.

Introduction: Parkinson's disease is one of the fastest-growing diseases in terms of prevalence, disability, and mortality. Exposure to environmental toxic substances, such as mercury (Hg) can increase the risk of neuronal damage and neurodegenerative diseases. Purpose: The purpose of writing this article is to determine the impact of mercury exposure on the incidence of Parkinson's disease in small-scale gold mining workers. Methods: The author searches for material through the Google Scholars, NCBI, and ScienceDirect search pages by limiting the journals published in 2015-2020. In this review, the authors conducted a study of 33 scientific articles. Results: The small-scale gold mining industry is the largest source of mercury emissions in the world. Mercury gas has a negative impact on the lungs, kidneys, liver, and nervous system. Gold miners have a very high likelihood of being exposed to metallic mercury and suffering occupational mercury intoxication. Discussion: Mercury is known to be a neurotoxin that can cause neuron death and damage to the substantia nigra and other basal ganglia nuclei. Acute mercury exposure can cause tremors, memory loss, respiratory distress, and even death. Gold miners are a group that is exposed to a lot of mercury and suffers from work-induced mercury intoxication. Conclusion: Mercury-induced parkinsonism can be identified because of its predilection for accumulation and palladium and striatum damage such as damage to the substantia nigra pars in Parkinson's disease.

The Colombian government and large-scale mining companies accuse small-scale gold miners of lacking a sense of the future, thereby harming the future of Colombia. In this article, I argue that marginalized people who extract gold with small-scale techniques create an alternative sense of future by engaging with the leftovers of their gold mining practices. This article is based on ethnographic fieldwork with people who struggle to make a living in the wake of large-scale mining interventions in the town of Marmato. Small-scale mining constantly creates simple by-products—gases, rubble, and mud—that look like waste. Small-scale miners engage with such substances as a way to make sense of their lives and the future. Making the relationships between humans and geological substances, waste and technology visible elucidates alternative forms of life that “get in the way” of a multinational mining company, the national government, local mafias, and financial markets hungry for gold in times of crisis. By analyzing people’s engagement with leftovers, I offer an understanding of resilience and survival in the margins of capitalist cycles of violence. Resumen El gobierno de Colombia y las compañías mineras a gran escala ven la minería a pequeña escala como una práctica sin futuro y dañina para el país. En este artículo argumento que las personas marginalizadas que extraen oro a pequeña escala crean sentidos de futuro alternativos al entrar en relación con las sobras de sus propias prácticas mineras. El artículo está basado en trabajo de campo etnográfico en el pueblo de Marmato, con personas que luchan por sobrevivir ante la inminencia de la ejecución de un proyecto de minería a gran escala en la montaña donde se localiza el pueblo. La minería a pequeña escala crea subproductos de manera permanente—colas, sobrantes y restos—que parecen basura. No obstante, los mineros a pequeña escala se involucran con estas sustancias como una forma de hacer sentido sobre sus propias vidas y futuros. Hacer visible la relación entre humanos y sustancias geológicas, desechos y tecnología hace posible apreciar formas alternativas de vida que “se ponen en el camino” de una multinacional minera, el gobierno nacional, mafias locales y los mercados financieros que buscan oro en tiempos de crisis. Al analizar la relación de las personas con gases, escombros, rocas, y barro, aporto una posibilidad de entender la resiliencia y subsistencia en los márgenes del capitalismo y sus ciclos de violencia.

The purpose of this service activity is to reduce the impact of mercury on small-scale gold mining communities through training and coaching activities in Sekotong village. The Sekotong region, West Lombok Regency is an area rich in potential gold resources with the potential to mine 1,596 tons of gold and can be mined for decades. This potential has been exploited by the community by traditional gold mining. The gold mining area in Sekotong is spread over 3 locations, namely Buwun Mas, Kerato and Pelangan involving 5000 traditional miners. Gold processing carried out in the community is by using amalgamation and cyanidation methods. The technology provided in this service activity is by eliminating the use of mercury in gold processing, reducing the use of cyanide, training and coaching on appropriate standard operating procedures in handling mercury and cyanide, and processing cyanide before it is discharged into the environment. The result of this community service activity is that with the application of this technology, the environment and traditional gold miners become safer and healthier.
