Available in PDF, EPUB and Kindle. Book excerpt: The gold rush in the Amazon region is creating serious environmental problems that imperil future generations. Mercury pollution is a particularly serious problem that should be addressed through an education campaign, through the use of more appropriate (and inexpensive) extraction technologies, and through an effective combination of command and control measures and market- based incentives.

Available in PDF, EPUB and Kindle. Book excerpt: The Amazon region has been responsible for a major share of Brazilian gold production in recent years. The region has witnessed a sizable gold rush comparable only to the California gold rush last century. The gold rush has spawned a powerful informal mining sector and has attracted many people - some who have come to the region in search of wealth and some who were already there but were displaced from other, unsuccessful economic activities. What these people encounter at the mining sites are dreadful living and working conditions. Gold mining also causes substantial environmental problems, which may persist whether gold deposits do or not. The author discusses the environmental effects of gold mining in the region, focusing on mercury pollution. Mercury, an important input in gold extraction, is being discharged into the atmosphere and the rivers at alarming rates. The environmental costs of the present extraction, is being discharged into the atmosphere and the rivers at alarming rates. The environmental costs of the present extraction technology will be faced primarily by future generations, because of natural chemical processes. Although removing the mercury already discharged from the Amazonian environment may be an enormous task, at least future discharges should be curtailed through the use of appropriate technology, environmental education, and a combination of command and control measures and market-based incentives. The author describes the gold extraction process and the extent of mercury use and contamination. He analyzes key elements of the environmental problem, especially the informal miner and the fish economy. Finally, he suggests a combination of command and control regulations and market-based incentives adapted to the informal gold mining economic environment. He emphasizes the need for an education campaign about the perils of using mercury and the availability of more appropriate, and inexpensive, alternative extraction technologies.

Download or read book Mercury from Gold and Silver Mining written by Luiz D.de Lacerda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its inherent characteristics, mercury contamination from gold mining is a major environmental problem compared to past mercury contamination from industrial point sources. The worsening of social-economical conditions and increasing gold prices in the late 1970s resulted in a new rush for gold by individual entrepreneurs for whom Hg amalgamation is a cheap and easily carried out operation. Even after the present-day mining areas are exhausted, the mercury left behind will remain part of the biochemical cycle of the tropical forest. This book reviews the current information on mercury from gold mining, its cycling in the environment and its long-term ecotoxicological impact. The book is illustrated with numerous diagrams and photographs.

Download or read book Rise of Mercury Emissions in the Amazon Rainforest an Evaluation of Artisanal and Small scale Gold Mining and Biomass Burning Sources written by Marcos J De la Cruz and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two important global sources of mercury emissions to the atmosphere are biomass burning (BMB) and artisanal and small-scale gold mining (ASGM) operations. These activities, prevalent in the Amazon rainforest, are driven by agricultural and cattle ranching expansion and rising international gold prices, respectively. Although there are indications of increasing ASGM activities in the Amazon, there are no studies of corresponding mercury consumption and emissions within this context. In this study, a regional assessment of mercury consumption and emissions from ASGM activities is made for the period between 2001 and 2014. Mercury consumption and emissions are derived from analyses of official and illegal gold production estimates and mercury imports. Between 2001 and 2014, annual ASGM mercury emissions from the region increased approximately 155% from 57.4 metric tons to 146.1 metric tons. If illegal gold mining occurring in the Amazon rainforest is considered, mercury emissions increase to 242 tons in 2014. Between 2001 and 2014, ASGM mercury emissions (excluding emissions from illegal gold mining) for the whole region were 1,339 metric tons. Similarly, over 3,420 metric tons of mercury were consumed and released to the environment as tailings and emissions with almost 65% coming from just 3 countries (Colombia, Peru, and Suriname) out of 8 countries and 1 overseas territory evaluated. In contrast, BMB mercury emissions derived from deforestation rates in the Amazon decreased 80% from 12.7 tons to 2.6 tons in the same period. Decrease of BMB emissions was driven by lower deforestation rates in Brazil. Between 2001 and 2014, approximately 105 tons of mercury were released to the atmosphere from deforestation activities. These results show the significant increase of ASGM mercury emissions in the Amazon rainforest, which would represent 12% of global mercury emissions from anthropogenic sources.
