Peruvian gold and mercury poisoning

An excellent article is yours to be read just by clicking this link and going over. Penned by Barbara Fraser, it's all about how high levels of mercury in the atmosphere in and around Peruvian gold shops selling wares from informal/illegal mining may be a very serious health hazard for the wider population. Here's how the note starts, make sure you click through for the rest and thanks due to the eversuperduper Jacqueline Fowks for the headsup. Great journalism.

Townspeople, gold shopkeepers highly exposed to mercury in Peru

Experts have long known Peru’s miners are exposed to extremely high levels of mercury. But now new research shows that the toxic threat has spread to towns in the Amazon and Andes Mountains where gold is sold. Inside Puerto Maldonado's gold shops, shopkeepers heat clumps of ore, releasing mercury vapors that waft into the shop, and then outside, into streets crowded with townspeople. Researchers detected mercury levels at a gold shop so extreme a monitor couldn’t measure them. Then, high in the Andes, they measured unsafe levels in the air outside the shops.

PUERTO MALDONADO, Peru -- On a busy, dusty street beside a huge open-air market, signs reading “oro” mark shops that trade in gold. The customers, mostly men in work clothes and rubber boots, have just arrived from the mining camps to sell their gold and wire money home.

Inside, shopkeepers heat the miners’ clumps of gold ore, releasing mercury vapors that waft into the shop, and then outside, into the streets crowded with townspeople.

Experts have long known Peru’s miners are exposed to extremely high levels of mercury. But now new research shows that the toxic threat has spread to towns in the Amazon and Andes Mountains where gold is sold.

In Puerto Maldonado, a jungle town in Madre de Dios, one of Latin America’s most productive gold mining areas, researcher Luis Fernández in 2009 detected mercury levels at a gold shop that were more than 20 times higher than an international worker safety standard. This February, his follow-up testing found mercury levels inside one shop that were so extreme his monitor couldn’t measure them.

Then, a week later, in a town high in the Andes, Fernández became truly alarmed when he measured mercury in the air outside the gold shops, and detected levels that exceeded the amounts considered safe.

“It seems clear that these workers are under extraordinary risk for acute mercury poisoning,” he said, adding that people outside the shops are highly exposed, too.

In the first study of its kind in Peru, Fernández and a team of researchers funded by the U.S. Environmental Protection Agency are measuring mercury pollution from gold shops in Puerto Maldonado, in the Amazonian lowlands, and La Rinconada, 15,000 feet above sea level in the Andes Mountains.

Their initial findings – coupled with new tests by Peru’s National Institute of Health that measured mercury in people’s urine – point to a public health risk in towns near informal mining camps, which have flourished with skyrocketing international gold prices.

UPDATE: IKN has the benefit of smart readers and one, who'll go by the name of 'Reader B' because he's not into fame and such, really knows his beans about all sorts of mining issues, including  mercury. Here's the mail he just sent in:

You know what is most upsetting to me about the mercury contamination from placer miners? It can be eliminated 98% by the use of a mercury retort, 500 year old technology. Any tinsmith/ mechanic/ plumber can make one for about $50, and it allows the miners to re-use the mercury again and again (so it would save them money) and save their health, the environment etc. See attached image, or Google your own.


Seriously, in 1556 Georgius Agricola wrote De Re Metallica, which instructs one in the art. One of the very earliest science text books.

I know a Yukon placer mining consultant who always takes one with him as a gift when he goes to visit placer mines in the third world. Biggest problem is the ultra-violence often found in illegal placer mining camps (see any episode of Deadwood). Often too scary to even approach these places.

Peru: Gold miners in Madre de Dios

An excellent piece of journalism in Peru's El Comercio today (a reminder of the newspaper that it used to be) bylined Nelly Luna, showing the ecological disaster area created in the Amazon jungle of Peru by informal gold mining. The Madre de Dios Region is home to an estimated 30,000 miners, nearly all of whom produce gold illegally and with no regard whatsoever to environmental regulations.

Here follows my translation of the full report, entitled "Brutal Deforestation of Madre De Dios", and watch out right at the end for a revealing interview with the Mining Ministry Flunkey, who knows what is happening, knows it's illegal and knows that around 50 metric tonnes of mercury legally imported into Peru ends up being illegally sold in the disaster area but doesn't want to do a thing to stop it. His arguments are laughable and clearly just wants to protect the status quo, not giving a damn about the enormous damage that current policies are causing. Viva investment grade.

Who will halt this criminal attack against nature?

Brutal Deforestation of Madre de Dios

Forests are converted into deserts due to the advance of informal mining that illegally extracts gold. Regular buying and selling of mercury is demanded by locals, who use it for the extraction of the precious metal.

An overflight of the jungle between Madre de Dios and Puno offers a panoramic portrait of the devastation; thousands of tonnes of earth removed and forests disappeared or buried beneath the tailings left by years of intense and illegal exploitation of gold in the Amazon. It is possible to make out improvised mining camps, heavy machinery turning over the red soil, flows of rivers cut off and enormous pools of water that hold an un-noticed poison that keeps on accumulating: mercury.

This element is as necessary in the exploitation of gold as kerosene is in the production of cocaine. Because of this, mining engineers and environmentalists argue that if the sale of mercury is regulated, in the same way as chemical supplies are to combat narcotrafficking, a large part of the problem of illegal mining and the destruction of the forests. But this doesn't happen; mercury is sold without any sort of control among the population that is found around the mining zones of Puno and Madre de Dios.

Supply and Demand
According to Customs information, in just the last four years the importation of mercury has nearly doubled, from 75,000kg imported in 2006 to 132,000kg last year. And so far this year, only up to September, there have been legal imports of 131,876kg of mercury. The Ministry of Energy and Mines (MEM) says that all these imports are basically used in artisanal mining, where levels of informality (no mining or land titles held or environmental impact studies approved) reach 90%.

For every gram of gold produced, two or three times as much mercury is needed. A recent study by Cáritas estimated that more than 50 tonnes of mercury is used in the Madre de Dios region per year- Despite the large scale of the mining exploitation, tax evasion due to the informality of the industry is enormous; this region receives only S/15,000 (U$5,200) in mining royalties from the state.

Up to March 2009, the Institute of Geology, Mining and Metallurgy (Ingemmet) and the MEM had authorized 1,592 mining concessions in Madre de Dios and only 19 have approved environmental impact studies, with another 1,089 in process. There are also 87 mining concessions that overlap the Peru State Nature Reserve of Tambopata. According the the MEM, the control of current illegal mining is the responsibility of the regional governments.

"The mining concessions have been authorized without taking into account other existing rights such as agricultural properties, forestry concessions, conservation concessions and protected areas" according to the diagnosis of the Ministry of the Environment. With this disorder of concessions and a lack of controls, mercury is feeding into waters, lands and even in fishes. In improvised stores located around the mining zones such as Huepetuhe or Inambari, where the taxman never appears, one kilo of mercury sells for between S/150 and S/180 (U$52 to U$63) in jars with the ticket names American Mercury or El Español.

No Clear Rules
National rules establish that all companies that use mercury must have mechanisms that allow for the recapture and re-use of mercury, but nothing more. There is no rule that regulates the adequate final disposal or the metal. Experts say that the ideal situation would be to take it to safe depositories overseas (Peru does not have any). Without clear rules, each year more and more tonnages of this dangerous element arrives to stay (or evaporate) in some part of the country.

It is worth mentioning that 83% of mercury imported by Peruvian companies comes from the United States or Spain. Mercantil SA, Triveño Mercury Corporation, JH Minerals, Aldo Orlando Torres Rojas and M&M Trading S.R.L. are the main importers. The quantities that arrive are mainly destined for the mining industry, with lesser percentages for the production of chlorine and dental curation work.

But mercury is not the only element used in illegal mining in the Puno and Madre de Dios regions. Every day, front load diggers arrive that cost half a million dollars apiece along with lorries, trucks, excavators and drags. The economic investment is very large, nothing to do with small mining. The Ministry of the Environment estimates that 50 truckloads of fuel arrives to the zone every day, 175,000 gallons of diesel and gas is used and approximately 1,500 litres of oil is spilled by the machinery and boats. Who will put a stop to this situation?

Interview with Víctor Vargas Vargas, Director General of Mining, MEM
"Prohibiting sales could generate contraband"

"If the commercialization of mercury is regulated, wouldn't it reduce illegal mining?

Mercury is freely traded. There are formal companies that import and sell it in a legal manner. If it were prohibited, it may generate contraband in this material.

Imports have nearly doubled in the last four years.

This is connected with the rise in price of gold, which causes a greater demand for mercury in the marketplace. What's more, 98% of informal mining activity in the country is dedicated to gold mining and the basic ingredient is mercury. What we would like is that the technical requirements of the recovery of this element are complied with.

Therefore, mercury that arrives legally to the country finishes as being sold to illegal mining.

Indeed. Anybody can buy mercury, just like they can buy gold. There are no restrictions. What is needed is to formalize these people and teach them to correctly handle this resource. Large mining companies do not use mercury, but cyanide. Mercury is only used in artisanal mining. However, there are mines that during the exploitation process obtain mercury as a byproduct, for example in Yanacocha, that is then exported.

Is there a regulation, as there is for cyanide, that locates the final destination that the mercury must have?

There is no rule about its control, but there is perhaps thought of creating one, without aggravating the already existing problems. Blocking its comemrcialization would stimulate a black market and a rise in the price of this material.

Mercury is funny stuff

Here's a list of interesting facts about Mercury (Hg) and some of the things that happen to people who come into contact with it (and some of the things that don't happen, too).

Almost certainly know:
Mercury is a very dangerous substance, highly toxic and can be ingested through simple touch.

Probably know:

Eight years ago in Peru there was a spillage of 151kg of mercury. The truck was servicing the Yanacocha gold mine and splashed mercury at various points on its route, including the village of Choropampa. Other places affected were Chotén, San Juan, La Calera, El Tingo and Magdalena.

Choropampa in all its glory

Might know:
Of the 151kg of mercury spilled, 49.1kg was recovered, 17.4kg was absorbed into the earth, 21.2kg evaporated and 3.3kg is still unaccounted for (all official numbers).

Unlikely to know:
The mayor of Choropampa, Vicente Zárate Minchán, died early Monday morning, 10th November 2008. He was 34 years old and had been displaying symptoms typical to mercury poisoning.

Very unlikely to know
According to the local doctor (please note the singular), there are 80 other people displaying the same symptoms as showed Mr Zárate, a syndrome known as Guillain-Barré. The local doctor also says that 10 people have already died that were displaying the same symptoms. This is the point where lawyers for Yanacocha mine will tell the world that there is no proven connection between the death of Mr. Zárate, the other symptoms shown by locals and the mercury spillage. They will also show the world pieces of paper to prove their point. That's fine by me. This is also the point when Otto tells Yanacocha's lawyers to go **** themselves with a sharp stick.

I'd be extremely surprised if you knew:
In the eight years since the accident, the medical infrastructure in the village of Choropampa has not changed an iota. It is still reliant on a Medical Post that has one obstetrice, one doctor, one nurse and one technician. Yanacocha claims that all locals have access to private health coverage, but the villagers note that to claim on the insurance they have to travel to the city of Cajamarca, a mockery for those seriously ill.

Funny stuff, mercury. Hilarious, in fact.
