With a new international treaty, an increasing number of African countries are committing to phasing out mercury, a significant health and environmental hazard.

Research has shown that maternal exposure to mercury from contaminated fish can cause learning disabilities in developing babies. When inhaled, mercury vapor can also affect the central nervous system, impair mental capacity and, depending on levels of exposure, even lead to death."The ripple effect of using mercury is very costly in both human health and harm to the environment.” --Olubunmi Olusanya

“Despite the danger that mercury poses, it is still widely used, especially in Africa, and this is of great concern,” says Olubunmi Olusanya of the Federal Ministry of Environment, Nigeria.

He told IPS that “While Africa does not manufacture mercury added products, the continent is a leading importer of mercury. The ripple effect of using mercury is very costly in both human health and harm to the environment.”

It is within this context that the Zero Mercury Working Group recently held a series of meetings in Nairobi, Kenya to address phasing out of mercury.

The Zero Mercury Working Group is an international coalition of over 95 public interest environmental and health non-governmental organizations from more than 50 countries around the world, with several NGO members coming from African countries.

“Phasing out mercury will mean replacing mercury added products such as thermometers, thermostats and batteries with alternatives, but it also means reducing and ultimately eliminating the use of mercury in artisanal and small-scale gold mining,” explains Elena Lymberidi-Settimo, International Co-coordinator of the Zero Mercury Working Group.

According to the Zero Mercury Working Group, artisanal and small scale gold mining (ASGM)  is a complex global development issue. It uses and releases substantial amounts of mercury in mineral processing, usually in highly unsafe and environmentally hazardous conditions.

Haji Rehani, a Senior Programme Officer at the Agenda for Environment and Response Development in Tanzania, who works closely with artisanal and small scale gold mining communities, says, “This kind of mining is the largest demand sector for mercury globally.”

He says that 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, exposing miners and contaminating the environment while leaving the gold behind.

“There is a need to engage as many stakeholders as possible from the miners all the way to governments,” he advises.

He told IPS that African governments have shown the greatest worldwide commitment to addressing mercury as a health hazard and to ultimately phase it out.

Rehani says that this commitment has been demonstrated through Africa’s active involvement in the adoption of the Minamata Convention on mercury in October 2013, when 128 countries signed on.

“This legally binding agreement was developed and adopted to protect human life and environment from mercury emissions. It has clear time-bound targets for phasing out the manufacture, export or import of a number of mercury added products specified in the Convention,” he expounds.

At the moment, 52 countries have ratified the Convention, marking a significant milestone since the Convention requires at least 50 countries to ratify in order for the treaty to enter into force.

The Convention will therefore come into effect in the next 90 days. This further reinforces the significance of the zero mercury conference, which provided a platform for cross-country knowledge sharing towards reducing and eventually eliminating the use of mercury in all sectors.

Desiree Narvaez of the UN Environment Chemicals and Health Branch explained the need for stakeholders to have a platform to address mercury as a global health and environment issue, noting that such platforms are essential for governments to understand the devastating impact of mercury use.

Of the 52 countries, Africa is ahead of every other continent with 19 countries ratifying the Convention.

The Zero Mercury Working Group has major ongoing intervention projects in, for instance, Nigeria and Mauritius, focusing on phasing out mercury added products by 2020 as stipulated in the Minamata Convention.

Other Zero Mercury projects are also in countries such as Ghana and Tanzania where the main focus has been reducing and eventually eliminating the use of mercury in artisanal and small scale gold mining.

These projects are also keen on protecting vulnerable populations, and specifically women and children.

Experts at the conference reiterated the fact that the use of mercury in artisanal and small scale gold mining continues to rise, especially in developing countries, mainly because it is considered simple and inexpensive – producing 20 to 30 percent of the world’s gold.

The Zero Mercury Working Group estimates that 15 million people in approximately 70 countries are employed in artisanal and small scale gold mining, with many exposed to mercury. Four to five million of them are vulnerable women and children.

As a result, there is a need for concerted efforts to protect such disadvantaged populations and for countries to ensure that their respective National Action Plans emphasize the protection of such vulnerable groups when implementing the Convention.

There was significant emphasis during the Nairobi conference on the need for governments to develop and implement the Convention, which contains mandatory obligations to eliminate where feasible, and otherwise minimize, the global supply and trade of mercury.

A key stakeholder during the conference and indeed in global efforts to phase out mercury is the United Nations Environment Global Mercury Partnership (UN Environment).

Within the context of the Minamata Convention the focus of the UN Environment Global Mercury Partnership has shifted to support crucial areas of the treaty.

This includes banning  a number of listed mercury added products by 2020, with the exception of a Party registering an exemption.

Reducing and ultimately eliminating the use of mercury in small scale gold mining is expected to be done progressively, with the objective achieved in about 15 years.

The meeting brought together many government officials and stakeholders in a one-day forum held on the heels of the Zero Mercury conference to develop their own road maps for phasing out mercury under the Minamata Convention by 2020.

This included 35 delegates from 31 countries, representatives of seven United Nations and intergovernmental agencies, 15 NGOs and five other delegates from academics, private sector and consultants.

It emerged from the meetings and experience sharing that there is a great need for country-specific laws to explicitly outlaw the use of mercury in products and taking voluntary steps to significantly reduce mercury in artisanal and small scale gold mining, since the treaty doesn’t specifically ban it.

For example, Uganda has signed the Minamata Convention and is in the process of developing a National Action Plan for reducing mercury in artisanal and small scale gold mining. While this will take this East African nation a step closer towards phasing out mercury, there is no legislation in place outlawing the use of mercury.

“In this regard, stakeholders must embrace as many partnerships as possible. Mercury is a cross-cutting issue and one single entity cannot address this agenda. We need the government, Civil Society Organizations, miners and others as was demonstrated during the Zero Mercury conference,” said Anne Lillian Nakafeero from the National Environment Management Authority in Uganda.

WASHINGTON, Oct 7 2013 (IPS)

A new international convention opening for signatures this week will for the first time offer an agreed-upon roadmap by which to significantly decrease the global use of mercury while offering stronger safeguards for both human health and the environment.

Environment and public health groups are hailing the treaty, a legally binding agreement known as the Minamata Convention on Mercury, the text of which was agreed to in January by 147 countries following four years of negotiations. Proponents are now calling on governments to move quickly to ratify the accord after it opens for signatures, on Wednesday during a four-day summit in Japan.“This is something we’ve worked on for over a decade, so it’s quite an amazing moment." -- Michael Bender of the Zero Mercury Working Group

The convention will come into effect following ratification by 50 countries, though several key parts of the agreement will only be enforced at the end of this decade or even later.

“Overall, this is a really positive step – while we would have liked to have seen a stronger section on health, just having health language in what was considered an environmental treaty is an achievement,” Jane Cohen, a researcher in the Health and Human Rights Division at Human Rights Watch, an advocacy group, told IPS.

“We see mercury exposure in this setting as a critical threat to children’s and women’s health, as well as a major issue around access to information. It’s a prime example of environmental degradation impacting directly on human lives.”

The Minamata Convention (named for the Japanese city that is the site of the worst modern mercury poisoning) will now lead ratifying countries to phase out – and, by 2020, to ban – the use of mercury in a range of consumer items, including certain batteries, light bulbs, medical devices, dental fillings and vaccines. It will also tackle mercury pollution at its two most common sources, small-scale gold mining and coal-fired power plants.

Indeed, it is due to these latter two sectors that the new convention’s effects will likely be particularly pronounced in developing countries. While most industrialised countries have reduced their use of mercury in recent decades, developing economies have seen a steep rise in the toxic metal’s use.

“This is the first time we’ve seen these kinds of protections in a convention, so in addition to requiring real, implementable steps, it also brings much-needed attention to this issue for governments,” Cohen notes.

“Any country that has small-scale gold mining must now have a national action plan to look at alternatives or ensure worker and environmental safety – countries won’t be able to just ignore this convention. In addition, some of the worst forms of this sector’s use of mercury – such as burning it – will be banned outright.”

According to estimates released earlier this year by the United Nations Environment Programme (UNEP), since 2005 mercury emissions have doubled in small-scale mining operations in Africa, Asia and South America. Today, Southeast and East Asia alone account for around half of global mercury emissions, put down to the regions’ rapid economic growth in recent years and rising gold prices.

No alternative to cooperation

International talks on the dangers posed by mercury began in earnest early last decade, and by 2003 countries had struck an initial agreement that the substance deserved to be considered a global pollutant warranting immediate international action. But it took another half-dozen years for serious negotiations, a process that was given new momentum by President Barack Obama’s election in 2008.

As a senator, Obama had urged the U.S. government to enter into negotiations towards a binding international mercury standard. After his election to the presidency, Obama was able to oversee an about-face in U.S. policy on the issue, a change that proved to be a catalyst for other countries, including China and India.

Simultaneously, many industrialised countries were already ratcheting down their own use of mercury, both for consumer and industrial purposes. In late 2011, the U.S. government unveiled strict new standards for mercury emissions from power plants, seen as one of the most important environmental victories of Obama’s first term.

“This is one of the compelling reasons why countries like the United States and other developed countries have moved to adopt the treaty, because they’ve already taken significant steps to phase out their use of mercury,” Michael Bender, a founder and international coordinator for the Zero Mercury Working Group (ZMWG), a network of groups in 50 countries, told IPS from the sidelines of the Japan summit.

“This is something we’ve worked on for over a decade, so it’s quite an amazing moment. No single country can solve the global mercury crisis – while there are alternatives to most products and processes and there are controls for most major sources, there is no alternative to global cooperation.”

Mercury, which can remain in natural environments for years, attacks the nervous system and has been proven to be particularly debilitating for unborn babies and children. According to new research released last week by the ZMWG, mercury levels in many human communities could be far higher than anticipated.

Looking at hair samples of women of childbearing age from nine countries, researchers found that nearly a quarter exceeded a widely accepted safety limit for a certain type of mercury set by the U.S. Environmental Protection Agency. Further, higher findings appear to correlate with higher consumption of fish and seafood, with 71 percent of women in Japan, for instance, exceeding this limit, followed by 64 percent of women in Spain.

While Bender expresses satisfaction with the Minamata Convention’s imminent passage, he and others have expressed concern over the agreement’s timeframe.

A new article he co-authored for the Journal of Public Health Policy warns that the convention “is slow to address major sources and uses of mercury. Coal-fired power plants constructed after the Convention enters into force are not required to install controls until 5 years later, with existing facilities given 10 years … Moreover, missing from the Convention are steps to eventually end mercury use in” small-scale gold mining.

Still, Bender and the ZMWG are now turning their attention to encouraging the convention’s timely ratification. They’re hoping to get the required 50 ratifications by 2015, and Bender says he’s optimistic that goal will be met.

“One good indication is the great number of environment ministers showing up here [in Japan], a dozen and a half from Africa alone,” he says.

“We also understand that a significant percentage of countries in the European Union are coming. Between the interest being demonstrated in Africa and the E.U. alone, we feel quite confident that the momentum for this international agreement will continue to build.”
