As new global mercury treaty enters into force, worldwide mercury production skyrockets, 
notes Global NGO Coalition on World Environmental Health Day

Geneva, 26 September 2017- As 156 countries convened for the first meeting of the Conference of the Parties to the Minamata Convention, 
a new UN report shows mercury mining skyrocketing in the last 5 years. Moreover, much of that mercury is used in artisanal and 
small scale gold mining (ASGM), the largest source of global mercury pollution.

Currently, countries do not have reliable information about trade in neighboring countries and within their own region. 
This problem is compounded where borders between countries are “porous,” and a significant portion of trade is informal or illegal. 
For example, mercury may enter a region through legal trade to one country, but then be traded illegally across borders to neighboring countries. 

“Informal trade is difficult to track, and therefore does not appear in the official trade statistics,” said Elena Lymberidi-Settimo, 
Project Manager, Zero Mercury Campaign at the European Environmental Bureau. 
“With timely reporting, Parties can better understand mercury flows in order to better enforce trade restrictions in the Convention.”

“In recent years there have been a number of shocks to the global market, resulting in a doubling of the price of mercury in the last 12 months alone,” 
said Michael Bender, Co-coordinator of the Zero Mercury Working Group. “In addition, EU and US export bans now in place have resulted 
in a major shift in the main trading hub to Asia.”

“The emergence over the past five years of new small-scale producers of mercury in Mexico and Indonesia has made a difficult situation worse,” 
said Satish Sinha, Associate Director at Toxics Link in India. “Between these two countries alone, around 1000 tonnes are produced annually.”

“The main objective of the Minamata Convention is to protect human health and the environment by, in part, simultaneously 
reducing mercury supply and demand,” said  Rico Euripidou, Environmental Health Campaign Manager at groundWork 
in South Africa. Without adequate reporting on the global movement of mercury it will 
be difficult to monitor the overall effectiveness of the Convention, say NGOs.

“Annual reporting is consistent with the requirements of other environmental conventions such as Basel and the Montreal Protocol,” 
said Leslie Adogame, Executive Director at Sustainable Research and Action for Environmental Development in Nigeria.
“Legal trade flows must be understood before informal or illegal trade can be adequately addressed.”

An analysis of publicly available UN COMTRADE data over the period 2013-2016 (see below) reveals that the majority of global mercury flows 
from commodity trading centres (such as Hong Kong, Singapore and the UAE) to developing country regions (such as Africa and Latin America) 
where mercury use in ASGM is prolific in response to the largest global gold rush the world has ever seen.

*The Zero Mercury Working Group (ZMWG) is an international coalition of over 95 public interest environmental and health non-governmental organizations from more than 50 countries from around the world formed in 2005 by the European Environmental Bureau and the Mercury Policy Project.  ZMWG strives for zero supply, demand, and emissions of mercury from all anthropogenic sources, with the goal of reducing mercury in the global environment to a minimum.  Our mission is to advocate and support the adoption and implementation of a legally binding instrument which contains mandatory obligations to eliminate where feasible, and otherwise minimize, the global supply and trade of mercury, the global demand for mercury, anthropogenic releases of mercury to the environment, and human and wildlife exposure to mercury.

Artisanal Small Scale Gold mining (ASGM)

Artisanal and small scale gold mining (ASGM) is a complex global development issue. 

ASGM uses substantial amounts of mercury in mineral processing usually in highly unsafe and environmentally hazardous conditions. Mercury is used to bind the gold to form an amalgam, which helps separate it from the rock, sand and other materials. The amalgam is then heated to vaporize the mercury leaving the gold behind.

The use of mercury in ASGM continues to rise especially in developing countries mainly because it is considered simple and inexpensive. It is believed that ASGM produces 20 – 30 % of the world’s gold or approximately 500-800 tonnes per annum.

An estimated 10-15 million artisanal and small scale gold miners globally in approximately 70 countries are involved and eventually exposed to mercury.

ASGM is the largest demand sector for mercury globally (estimated at 650-1000 tonnes in 2005).

The amount mercury released within ASGM is dependent on the technique applied. The existing techniques include:

1.     Whole Ore amalgamation

In this process, mercury is added to all the ore being processes during crushing, grinding and sluicing. This is the most polluting way to use mercury. In many cases, only 10% of the mercury added to an amalgamating barrel or pan combines with gold to produce the amalgam. The rest (90%) is excess and must be recycled or released into the environment. This subsequently leads to widespread mercury levels in the surrounding environment and the most severe health exposure to the miners as well as non-miners.

2.     Gravity concentration (Panning)

This very common process involves concentrating gold with the heavier particles in the pan, while the lighter particles are sluiced away. Mercury is then added to the concentrates in order to amalgamate or gather the fine gold particles. About 10-15% of mercury releases from the ASGM are as a result of this process.

3.     Burning amalgam

Gold is also recovered from heating the amalgam through burning it in a metal pan over an open fire.When this is done without the use of a retort, mercury vapours are released into the air and inhaled by the miners.This practice produces atmospheric mercury emissions of about 300 metric tones per year worldwide. (GMP, 2006). The use of retorts to collect the mercury vapour can prevent mercury release into the atmosphere therefore reducing exposure to miners and the surrounding communities. With the use of retorts, about 95% of the mercury is recycled and can be re-used.

 Low mercury and mercury free solutions are available.

Relevant legislation and NGO policy work

In the EU

In the EU no ASGM takes place, apart from the French territories ofGuiana- where officially mercury use is prohibited under French law.

A relevant piece of legislation however is the EU Mercury Export Ban Regulation

Globally

Several projects and initiatives have been and  taking place globally, to reduce emissions from the sector.

The Global Mercury Project (UNIDO/UNDP/GEF) began in 2002 with a vision to address the environmental issue of mercury contamination from artisanal and small-scale gold mining (ASGM) and to demonstrate ways of overcoming barriers to the adoption of best practices and pollution prevention measures that limit the mercury contamination of international waters from this sector. Six countries have been formally participating in the GMP:Brazil, Lao PDR,Indonesia,Sudan,Tanzania andZimbabwe. The GMP aims to introduce cleaner technologies, train miners, develop regulatory mechanisms and capacities within Government, conduct environmental and health assessments (E&HA) and build capacity within participating countries which will continue monitoring Hg pollution after the project.

Important work is currently being carried out under the UNEP Global Mercury Partnership on Reducing Mercury in ASGM. The partnership is lead by UNIDO and NRDC (Member of ZMWG).

A global inventory of ASGM projects is available.

Smaller on the ground projects have been taking place in Tanzania , funded by NGOs such as the Swedish Society for Nature Conservation, the European Environmental Bureau/Zero Mercury Working Group and the Artisanal Gold Council.

The ZMWG has been following this issue closely and has been giving respective feedback at the global mercury negotiations. See also the ZMWG fact sheet  on Artisanal and Small Scale Gold mining (ASGM) (Jan 2011).

In the US the   Mercury Export Ban Act of 2008 is also a relevant piece of legislation - http://www.epa.gov/hg/regs.htm
