Scales of Responsible Gold Mining: Overcoming Barriers to Cleaner Artisanal Mining in Southern Ecuador
Gold mining by itinerant miners is acknowledged by the International Labour Organization (ILO) as the means of livelihood for more than 13 million people in the developing world. Though there are many potential socio-economic benefits of smallscale mining, there are also negative impacts from these small and inefficient operations due to wasteful extraction and processing techniques, often invo...
متن کاملGold Mining in Ecuador: A Cross-Sectional Assessment of Mercury in Urine and Medical Symptoms in Miners from Portovelo/Zaruma
Mercury is a toxic metal and is used in small scale gold mining. In Portovelo, Ecuador, mercury has been an environmental and health problem for decades. The target of this study was to assess the mercury concentration in the urine of miners from Portovelo/Zaruma to establish a prevalence of high values. Eight hundred and sixty-five (865) urine samples were collected and analysed for their merc...
متن کاملMonitoring of mining induced surface deformation
The main objective of the project ”Monitoring of mining induced surface deformation” (ALOS-RA-94) is to evaluate multi-temporal PALSAR data for land surface deformation monitoring, using interferometric techniques. Differential interferometry using PALSAR data over several mining sites in Germany, Poland and Czech Republic, as well as over alpine landslides in Switzerland and Italy was used to ...
متن کاملArtisanal Mining of Gold with Mercury in Ghana
The paper examines the environmental impact of artisanal mining of gold with mercury (Hg) in Ghana. In spite of its positive socioeconomic contributions, it is well known that artisanal mining of gold contributes in no small measure to land degradation, loss of biodiversity and natural resources, deforestation, water pollution, etc. In Ghana, these environmental problems remain poorly studied. ...
متن کاملMercury contamination associated with artisanal gold mining on the island of Mindanao, the Philippines.
The Agusan River basin of eastern Mindanao, the Philippines, hosts several centres of artisanal gold mining, the most important of which, Diwalwal, is a significant gold producer in global terms. An investigation of the environmental impacts of artisanal mining in the Agusan system, with particular reference to mercury contamination, was initiated in 1995 following reports of several incidents ...
