One gold mine — the Jerritt Canyon mine near Elko — reported emitting 9,400 pounds in 1998, the largest source of mercury pollution in the nation. Together, four northern Nevada gold mines reported emitting 13,560 pounds. The large releases surprised both regional EPA officials and the mining industry.


Gold mining causes serious mercury pollution . According to the statistics of the United Nations Environment Programme, the outdated mercury alchemical method is still used in small gold mines in about 70 countries around the world. It is estimated that 35% of the mercury released into the air in the world comes from small gold mines. The ...

In one study by Eckley et al. (2011), mercury emissions under ambient conditions at a Nevada gold mine, anywhere from <1500 to 684,000 ng m-2 day-1, were found to be orders of magnitude greater than emissions from the natural surrounding areas. Rates of mercury emission are highly variable and depend on the following factors:


Gold Mines are a source of mercury air pollution and are the fifth largest source of mercury air emissions in the U.S. Nevada mines produce fully 25% of all mercury air emissions west of Texas, but there are no federal regulations requiring gold mines to control their mercury emissions (TRI Data, Environmental Protection Agency, 2002).


Background 23 facilities in U.S. (15 in Nevada and 8 in other Western States) Gold Mines were identified in the 1999 National Emissions Inventory as a source of mercury emissions (estimated 11.5 tons per year) Most emissions were from facilities located in Nevada Initial Nevada Voluntary Program (2001-04) achieved some reductions Targeted 5 large facilities

Washington, DC – The Environmental Protection Agency released the 2003 Toxics Release Inventory (TRI) data today, which documents gold mines as the largest source of mercury air emission in the tri-state region of Utah, Idaho and Nevada. These toxic emissions are largely released by mines that use ore roasters to process the gold.


Of the 12 largest sources of mercury air pollution among U.S. gold mines, eight are in Nevada, according to Earthworks. The state is the world's sixth-largest gold …


year, the state's four largest gold mining companies entered into an innovative partnership program with the Nevada Division of Environmental Protection and EPA Region 9 to significantly reduce mercury air emissions. This Voluntary Mercury Air Emission Reduction Program (VMRP), set emission reduction goals at 33% by 2003 and 50% by 2005. The ...

Mercury Air Emissions from Gold Mines - Earthworks Mercury Air Emissions from Gold Mines According to the EPA's Toxics Release Inventory, gold mines are a leading source of toxic mercury air pollution in the U.S. Mercury pollution: from gold ore to your table


Scientists have reported high mercury concentrations in fish and waterfowl down-wind from Nevada s large gold mines, generating significant concern from down-wind states of Idaho and Utah. The EPA isn't taking steps to address the problem, so we are taking steps through the community Right to Know Act," said Dan Randolph of Great Basin Mine Watch.


"Some years ago, the gold industry voluntarily undertook a program to reduce mercury air emissions." Nevada produces 81 percent of …

The TRI did reveal the extent of mercury mining pollution. According the TRI, metal mining accounted for 90% of all reported mercury releases, 6.22 million pounds. Despite this, no federal regulations require mines to reduce mercury air emissions. Read EARTHWORKS' press release; Visit the TRI website.

Air quality is also compromised by gold mining, which releases hundreds of tons of airborne elemental mercury every year. Gold has traditionally been a gift of love, and, not surprisingly, jewelry ...


As for the representative nature of the Nevada open-pit gold mines, Gold Quarry was identified by Earthworks (an extractive industry NGO) as being a producer of dirty gold due to its mercury emissions (Earthworks et al., 2006). In contrast, the Phoenix gold mine was chosen simply because production and mercury emission estimates were available.


Most of the nation's 20 such plants are in Nevada, the richest gold mining state in the nation. The facilities are the sixth largest source of mercury air emissions in the country, according to EPA.


According to the Ban Mercury Group, as much as 95 percent of all mercury used in small-scale gold mining is released into the environment, constituting a dangers on all fronts—economic, environmental and human health. It is estimated that over 13 million people work as artisanal miners worldwide. Health Impact

The Mercury Problem in Artisanal Gold Mining. Mercury-based artisanal and small-scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.
